Root canals have a success rate of around 95% — which means that for the vast majority of patients, a single procedure is all it takes to eliminate infection and save the tooth. But occasionally, a tooth that has already been treated continues to 
cause problems. Infection persists at the tip of the root, symptoms return, or a hidden issue that couldn’t be addressed through the crown of the tooth is preventing full healing.
When that happens, an apicoectomy may be the best path forward. It’s a minor surgical procedure — and for many patients, it’s what stands between keeping a natural tooth and losing it entirely.
Here’s a clear explanation of what an apicoectomy is, how it works, and when your endodontist might recommend one.
What Is an Apicoectomy?
An apicoectomy — also called root-end surgery — is a minor surgical procedure that targets the very tip of a tooth’s root (called the apex) rather than approaching the tooth from the crown down, as a conventional root canal does.
During the procedure, your endodontist makes a small incision in the gum tissue near the affected tooth to access the root tip and the surrounding bone. The last few millimeters of the root — along with any infected tissue — are removed. The root tip is then cleaned, shaped, and sealed with a small filling to prevent bacteria from re-entering.
Over the following weeks and months, the jawbone naturally heals around the treated area, and the tooth is preserved.
You can learn more about the procedure directly on our Apicoectomy page.
How Is It Different from a Root Canal?
A conventional root canal approaches the tooth from the top — through the crown — to clean, disinfect, and seal the canals from the inside out. This works well for the vast majority of cases.
An apicoectomy approaches from the bottom up, through a small opening in the gum and bone near the root tip. Rather than working through the full length of the canals, the procedure targets the very end of the root where infection may be lingering or where the canals are too complex to fully clean through conventional means.
The two procedures address the same problem — infection or inflammation at the root — but from different directions and for different circumstances.
When Is an Apicoectomy Necessary?
An apicoectomy is not a first-line treatment. It is typically considered after a conventional root canal — and in some cases a retreatment — has not fully resolved the problem. Your endodontist may recommend an apicoectomy in the following situations:
Persistent infection after root canal therapy
Sometimes, even after a thorough root canal, infection remains at the tip of the root. This can happen because the root canal system is more complex than imaging initially revealed, or because a small pocket of infection was beyond the reach of conventional instruments.
Root canal retreatment is not feasible
In some cases, reopening and retreating the tooth isn’t possible or advisable — for example, if a post or crown makes access impractical, or if prior treatment has already been attempted more than once. An apicoectomy offers an alternative surgical route to address the problem.
Hidden canals or missed anatomy
Teeth — particularly molars — can have root canal systems that are far more intricate than they appear on a standard X-ray. An apicoectomy, combined with 3D cone beam CT imaging, allows the endodontist to identify and address anatomy that was not visible or accessible during the original treatment.
Calcium deposits blocking the canals
Over time, calcification can narrow or completely block the interior of a root canal, making it impossible to clean through conventional methods. An apicoectomy allows the endodontist to address the problem at the root tip without needing to navigate through the blockage.
A cracked root tip that cannot be repaired
When a crack extends into the lower portion of the root but not the entire length, removing the cracked section via apicoectomy may allow the remainder of the tooth to be preserved. If the crack extends too far, extraction may be the only option — and your endodontist will be straightforward with you about which applies.
Bone loss near the root tip
In some cases, infection-related bone loss has occurred around the root tip. An apicoectomy clears the infected tissue, allowing the bone to regenerate and stabilize the tooth over time.
What to Expect During the Procedure
Apicoectomies are performed under local anesthetic, so the area is fully numb before anything begins. Most patients are surprised by how manageable the experience is — the procedure is shorter and less involved than many people expect.
Here’s a general overview of what happens:
- A small incision is made in the gum tissue near the affected root to expose the bone and root tip
- A tiny opening is created in the bone to allow access to the root tip and any surrounding infected tissue
- The last few millimeters of the root are removed along with any infected tissue
- The root tip is cleaned with ultrasonic instruments and sealed with a biocompatible filling material
- The gum is sutured closed and healing begins
The entire procedure typically takes 30 to 90 minutes depending on the location and complexity of the tooth. Most patients return to normal activity within a day or two, with some mild soreness at the incision site that resolves within a week or so.
Is It Painful?
During the procedure, the area is fully numbed with local anesthetic and most patients feel little to no discomfort. Afterward, some tenderness and mild swelling near the incision site is normal and typically manageable with over-the-counter pain relievers. If antibiotics are needed due to active infection, they will be prescribed.
For patients with significant dental anxiety, our team also offers IV sedation to make the experience as comfortable as possible from start to finish.
Learn more about our IV Sedation options.
What Is the Success Rate?
Apicoectomies have a strong track record. Studies consistently show success rates of 85–97% depending on the tooth, the extent of infection, and the technique used. Modern microsurgical approaches — using surgical microscopes, ultrasonic instruments, and advanced sealing materials — have significantly improved outcomes compared to older methods.
At Phoenix Endodontic Group, we use surgical microscopes and 3D cone beam CT imaging to ensure the most precise, thorough treatment possible. In many cases, an apicoectomy is what allows a tooth to be preserved when all other options have been exhausted.
What Happens If an Apicoectomy Isn’t Performed?
If persistent infection at the root tip is left untreated, the consequences can escalate:
- The infection can spread to surrounding bone and soft tissue
- A dental abscess may develop or worsen
- The tooth may ultimately require extraction
- Bone loss in the area can complicate future tooth replacement
For patients who want to keep their natural tooth and have already exhausted conventional treatment options, an apicoectomy is often the last viable alternative to extraction. It is worth pursuing.

It starts small — a twinge when you bite down, a little sensitivity to hot or cold, maybe some tenderness along the gumline. It’s tempting to brush it off, especially if the pain comes and goes. But a tooth infection doesn’t resolve on its own. Left untreated, 
it can escalate from a minor annoyance into a serious health emergency. Here’s what actually happens when a tooth infection is ignored — and why acting early makes all the difference.
How a Tooth Infection Starts
Tooth infections usually begin with untreated decay, a crack, or trauma that allows bacteria to reach the pulp — the soft tissue at the center of your tooth containing nerves and blood vessels. Once bacteria invade the pulp, your body’s immune response kicks in, but the enclosed space of the tooth means pus and inflammation have nowhere to escape. This buildup is what eventually forms a dental abscess.
Stage 1: Localized Pain and Sensitivity
In the earliest stage, symptoms are often mild and easy to dismiss: occasional throbbing, sensitivity to temperature, or slight tenderness when chewing. Many people wait here, hoping the discomfort will pass. Unfortunately, this is exactly when treatment is simplest — and waiting only allows the infection to dig in deeper.
Stage 2: Abscess Formation
As the infection progresses, pus collects at the root tip, forming a visible or palpable abscess. Symptoms intensify — constant throbbing pain, swelling of the face or jaw, a bad taste in the mouth, and sometimes a low-grade fever. At this stage, the infection is actively damaging the surrounding bone and tissue, and home remedies or over-the-counter pain relievers only mask the problem.
Stage 3: Spreading Infection
If still untreated, the infection doesn’t stay put. It can spread to the jawbone, into the soft tissues of the face and neck, and in rare but serious cases, into the bloodstream or up toward the sinuses and brain. Swelling can begin to affect breathing or swallowing, which is a medical emergency requiring immediate attention — not a wait-and-see situation.
Why Prompt Treatment Matters
The earlier a tooth infection is treated, the more likely your natural tooth can be saved through root canal therapy — removing the infected pulp, disinfecting the canal, and sealing the tooth so it can keep functioning normally. Wait too long, and extraction may become the only option, which opens the door to a separate set of problems: shifting teeth, bone loss, and the cost and time of replacement options like implants or bridges.
Frequently Asked Questions
Can a tooth infection go away without treatment?
No. Antibiotics may temporarily reduce swelling or discomfort, but they don’t eliminate the source of the infection inside the tooth. Only endodontic treatment or extraction resolves it permanently.
How do I know if my tooth infection is an emergency?
Facial swelling, difficulty breathing or swallowing, a fever, or rapidly worsening pain are signs you need urgent care immediately — head to an emergency room if breathing or swallowing is affected.
Is it too late for a root canal if I’ve waited a long time?
Not necessarily. Many teeth can still be saved even after prolonged infection. The only way to know is a prompt evaluation — the longer you wait, the fewer options you may have.
Don’t Wait Out a Tooth Infection
If you suspect a tooth infection, don’t wait for it to get worse. Phoenix Endodontic Group offers same-day emergency appointments to diagnose and treat infections quickly, with the goal of saving your natural tooth whenever possible.

You made it through your root canal — and now you’re wondering what you can actually eat. This is one of the most common questions patients ask before leaving the office, and it’s a good one. What you eat in the days following your procedure can make a real difference in how quickly you heal, how comfortable you feel, and whether your tooth stays protected while it recovers.
Here’s everything you need to know about eating after a root canal, from the first few hours through the days that follow.
First: Wait Until the Numbness Wears Off
Before you eat anything, give your mouth time to fully recover from the local anesthetic. Numbness from the injection can last anywhere from two to four hours after your procedure — and eating while numb is an easy way to accidentally bite your cheek, tongue, or lip without realizing it.
It also makes it harder to gauge the pressure and temperature of food, which can stress the treated tooth or surrounding tissue. The safest approach is to wait until full sensation has returned before eating your first post-procedure meal.
What to Eat the Day of Your Procedure
Once the numbness has resolved, stick to soft, cool, and easy-to-chew foods for the first 24 hours. The goal is to minimize pressure on the treated tooth and avoid anything that could irritate the area or disrupt the temporary restoration.
Good options for day one:
- Yogurt — smooth, cool, and easy to eat with no chewing required
- Applesauce — gentle and soft with no hard pieces
- Scrambled eggs — soft, protein-rich, and easy on the jaw
- Mashed potatoes — filling and completely soft; skip any crunchy toppings
- Smoothies and protein shakes — a great way to get nutrients without chewing; avoid using a straw (the suction can create pressure)
- Soup — lukewarm broth-based soups work well; avoid very hot temperatures
- Soft fish — like tilapia or cod, which flakes easily and requires minimal chewing
- Bananas — naturally soft and easy to eat
- Pudding or gelatin — light, cool, and effortless
Keep temperatures mild — not too hot and not too cold. The treated area may be more sensitive than usual, and temperature extremes can cause discomfort even when the nerve has been removed, due to the surrounding gum and bone tissue still recovering.
What to Eat in the Days Following Your Root Canal
By day two and three, most patients start feeling noticeably better. You can gradually introduce more variety into your diet, but continue favoring softer foods and chewing on the opposite side of your mouth from the treated tooth whenever possible.
Good choices for days 2–5:
- Pasta — cooked soft; avoid hard-edged shapes
- Rice and grains — gentle and easy to chew
- Soft-cooked vegetables — steamed or roasted until tender; avoid anything crunchy or raw
- Avocado — soft, nutrient-dense, and easy to eat
- Soft bread — without a hard crust
- Oatmeal — warm (not hot) and filling
- Hummus — a versatile soft option with good protein
- Soft cheeses — easy on the jaw and a good source of calcium
- Ground or shredded meat — such as slow-cooked chicken or beef that pulls apart easily
The key principle: if it requires you to bite down hard or chew with significant force, it’s worth waiting a bit longer before adding it back.
Foods and Drinks to Avoid After a Root Canal
Certain foods can interfere with healing, stress the treated tooth, or damage the temporary restoration that protects the tooth until your permanent crown is placed. Avoid the following until you’ve received your final restoration and your endodontist or dentist has cleared you:
Hard and crunchy foods:
- Ice — one of the worst offenders; biting ice can crack a tooth even under normal circumstances
- Nuts and seeds — hard and easily get lodged around the treated area
- Raw carrots, apples, and firm vegetables — require too much biting force
- Chips, crackers, and pretzels — the hard edges can press against sensitive tissue
- Hard candy or granola bars
Sticky and chewy foods:
- Gum — can pull at the temporary restoration
- Caramel and toffee — sticky candies can dislodge or damage temporary fillings
- Chewy bread or bagels — the pulling motion strains the tooth
- Dried fruit — surprisingly sticky and tough on recovering teeth
Temperature extremes and irritants:
- Very hot beverages — hot coffee, tea, or soup can cause discomfort and inflammation
- Very cold foods — ice cream, frozen drinks, and very cold water can trigger sensitivity
- Alcohol — can interfere with healing and interact with any medications prescribed
- Acidic foods and drinks — citrus juice, soda, and vinegar-based foods can irritate the treated area
A Note About the Temporary Restoration
At the end of your root canal, the tooth is sealed with a temporary filling to protect it until your general dentist can place a permanent crown. This temporary restoration is functional, but it is not as strong or durable as the final crown.
Eating hard, sticky, or crunchy foods before your permanent crown is placed puts the temporary restoration at risk of cracking, loosening, or coming out entirely — which can expose the tooth to bacteria and reinfection. Following dietary precautions until your final restoration is in place is one of the most important things you can do to protect your treatment investment.

When Can You Return to Eating Normally?
Most patients are able to return to their regular diet within a few days of their procedure, as long as they continue to favor the opposite side of the mouth until the permanent crown is placed. Once the crown is cemented and fully set — which your dentist will confirm — you can eat normally without restriction.
Every patient’s recovery is a little different. If you’re experiencing significant pain, swelling, or sensitivity that is getting worse rather than better after the first couple of days, that’s worth a call to our office. Mild soreness is expected; escalating discomfort is not.
General Recovery Tips Beyond Diet
In addition to watching what you eat, a few other habits support a smooth recovery:
- Take any prescribed medications as directed. If anti-inflammatory or antibiotic medications were prescribed, complete the full course.
- Avoid smoking. Smoking slows healing and increases infection risk.
- Rinse gently. A warm saltwater rinse can help keep the area clean; avoid vigorous swishing in the first 24 hours.
- Sleep with your head slightly elevated. This can help reduce swelling overnight.
- Don’t skip your crown appointment. The temporary restoration is not meant to be permanent. Delaying the crown places the tooth at risk.

It starts with a twinge. Maybe a brief flash of sensitivity when you drink something cold, or a dull ache that comes and goes. You take some ibuprofen, it calms down, and you move on with your day — hoping it was nothing.
Sound familiar? You’re not alone. Waiting out tooth pain is one of the most common things people do. But is it ever actually safe? And how do you know when the tooth is healing on its own versus when it’s quietly getting worse?
Here’s an honest look at what your tooth can — and can’t — recover from on its own.
The Short Answer: It Depends on What’s Wrong
Not all tooth pain is created equal. Some discomfort is temporary and harmless. Other pain is a signal that something serious is happening inside the tooth — and that’s where waiting becomes risky.
The key is understanding the source of the pain. Here are the most common scenarios:
When Tooth Discomfort Can Resolve on Its Own
There are a few situations where mild discomfort may settle down without treatment:
- After a recent dental procedure. It’s completely normal to feel sensitivity or soreness for a few days after a filling, cleaning, or crown placement. This typically resolves on its own as the tooth settles.
- Minor enamel sensitivity. If you’ve been using whitening products, eating a lot of acidic foods, or brushing too hard, you may experience temporary sensitivity. Cutting back on the trigger often helps.
- A very small, superficial crack. Tiny surface cracks (called craze lines) in the enamel don’t always require treatment and may not cause pain at all.
In these cases, keeping an eye on things makes sense. But “keeping an eye on it” means monitoring closely — not indefinitely ignoring it.
When Waiting Makes Things Significantly Worse
Here’s where things get important. If the pain involves the inner part of the tooth — the pulp, which houses the nerves and blood vessels — it will not get better without treatment. In fact, it almost always gets worse.
Signs the pain is coming from inside the tooth include:
- Throbbing or intense pain that lingers for more than a few days
- Sensitivity to hot or cold that doesn’t go away within 30 seconds
- Pain that worsens when you bite down
- A tooth that looks darker than the ones around it
- Swelling in the gum near the tooth, or a small pimple-like bump
- Pain that wakes you up at night
These are all signs of pulpitis — inflammation or infection of the tooth’s inner pulp. And here’s the thing about pulpitis: in its early stages, it may be reversible. Let it go long enough, and it becomes irreversible. The nerve dies, infection sets in, and what could have been a straightforward root canal may become an abscess requiring more complex treatment — or worse, tooth loss.
The “It Stopped Hurting” Trap
This is one of the most common reasons people delay care — and one of the most misleading signals a tooth can give you.
When a tooth that has been hurting suddenly goes quiet, it can feel like good news. But in many cases, it means the nerve has died. The infection is still there. The bacteria are still spreading. There’s just no nerve left to send a pain signal.
A tooth that has stopped hurting after weeks of pain should be evaluated by an endodontist — not celebrated. Painless doesn’t mean problem-free.
What Happens When an Infection Is Left Untreated
Dental infections are not self-contained. Without treatment, they can:
- Spread to the jawbone, causing bone loss
- Create a dental abscess that can rupture and spread to surrounding tissue
- In rare but serious cases, spread to the neck, airway, or bloodstream — a life-threatening complication
- Affect neighboring teeth, leading to more extractions
The longer an infection is left alone, the more complex — and costly — the treatment becomes. A root canal performed early is far simpler than managing a spread infection or replacing a lost tooth with an implant.
So What Should You Actually Do?
Here’s a simple rule of thumb: if tooth pain or sensitivity has lasted more than a few days, or comes with any of the warning signs listed above, it’s time to get it checked out. You don’t have to be in agony to call an endodontist. Earlier is always better.
At Phoenix Endodontic Group, we use advanced diagnostics — including 3D cone beam CT imaging and surgical microscopes — to find out exactly what’s going on inside your tooth. Many issues that feel minor from the outside are more progressed than they appear, and catching them early gives us the best chance of saving your natural tooth. Learn more about our approach on our Root Canal Therapy page.
The Bottom Line
Can a tooth heal itself? Sometimes — but only in a narrow set of circumstances, and never when the inner pulp is involved. The longer you wait on pain that doesn’t resolve, the fewer options you have.
Tooth pain is your body’s way of asking for help. Don’t wait until it stops asking.

If you’ve been told you need a root canal, your first instinct may be dread. Root canals have a long-standing reputation for being painful and unpleasant — but the reality is that modern endodontic care has come a long way. At Phoenix Endodontic Group, we use the GentleWave Procedure, one of the most advanced root canal technologies available today, to make treatment faster, more comfortable, and more effective than ever before.
But what exactly is GentleWave, and how does it compare to a traditional root canal? Here’s everything you need to know.
What Is a Root Canal — and Why Is It Needed?
Inside every tooth is a soft layer of tissue called the pulp, which contains nerves and blood vessels. When the pulp becomes infected or inflamed — due to deep decay, a crack, or injury — it needs to be removed to save the tooth.
A root canal is the procedure used to clean out that infected pulp, disinfect the inner canals of the tooth, and seal it to prevent reinfection. Without treatment, the infection can spread, cause an abscess, and ultimately result in tooth loss.
You can learn more on our Root Canal Therapy page.
How Does a Traditional Root Canal Work?
In a conventional root canal, the endodontist manually cleans the canals using small hand files and irrigating solutions. While this approach has successfully treated millions of patients, it does have limitations:
- Complex anatomy is harder to clean. Tooth roots branch into intricate micro-canals that hand files simply can’t reach.
- Multiple appointments may be needed. Because cleaning is more labor-intensive, traditional root canals sometimes require two visits.
- More tooth structure may be removed. Traditional filing techniques require more drilling, which can weaken the tooth over time.
- Some bacteria can remain. Microscopic spaces can harbor bacteria that lead to reinfection.
What Is the GentleWave Procedure?
GentleWave is a state-of-the-art root canal system that uses a powerful combination of fluid dynamics and acoustic energy to clean the entire root canal system — including the microscopic spaces that traditional instruments can’t reach.
A slim GentleWave instrument is placed in the tooth’s opening and specially formulated irrigating fluids are delivered in a controlled flow, creating tiny imploding bubbles. This process shakes loose debris, dissolves bacteria, and flushes biofilm from even the deepest, most complex parts of the root system — resulting in a cleaner canal with less mechanical disruption to the tooth itself.

GentleWave vs. Traditional Root Canal: Key Differences
Cleaning Effectiveness
- Traditional: May leave bacteria in hard-to-reach micro-canals.
- GentleWave: Cleans more than 98% of organic material, including spaces instruments can’t physically enter.
Invasiveness
- Traditional: Requires more filing and drilling to access and clean the canals.
- GentleWave: Minimally invasive — less drilling means more of your natural tooth structure is preserved.
Number of Appointments
- Traditional: Often requires two or more visits.
- GentleWave: Many patients complete treatment in a single session.
Post-Treatment Comfort
- Traditional: Some discomfort and soreness for several days after treatment is common.
- GentleWave: More than 96% of patients report no pain 48 hours after their procedure.
Best For
- Traditional: Straightforward cases with simpler root anatomy.
- GentleWave: All cases — especially teeth with multiple canals, complex root systems, or previous treatment failures.
Who Is a Good Candidate for GentleWave?
Our endodontists recommend the GentleWave Procedure whenever possible. It is particularly beneficial for:
- Teeth with complex or curved root canal systems
- Patients who want to complete treatment in fewer visits
- Patients with dental anxiety who want a gentler experience
- Cases where a previous root canal has failed and retreatment is needed
- Anyone who wants the most thorough cleaning possible to minimize reinfection risk
The best way to find out if GentleWave is right for you is to schedule a consultation with one of our endodontists, Dr. Jacqueline S. Allen or Dr. James F. Wolcott.
