When Is a Cracked Tooth More Than Just Cosmetic?
Fixing a cracked tooth is similar to inspecting a car after a fender bender—what looks like a minor issue can hide deeper structural damage. Without a professional evaluation, a surface-level chip or crack may go unnoticed until it worsens.
Unlike bone, teeth can’t regenerate. So, even a small crack in the enamel or dentin may expand with chewing, grinding, or exposure to hot and cold foods. Left untreated, these cracks can progress to the soft inner pulp, where the tooth’s nerves and blood vessels are located. This can cause pain, sensitivity, and infection.
Why You May Need a Root Canal Before a Crown
When treating a cracked tooth, your best resource is an endodontist. These dental specialists are highly trained in diagnosing and treating issues within the tooth, especially damage that affects the root or pulp. They are often the first to determine whether a root canal is necessary before a crown can be safely placed.
A dental crown serves to protect and restore the tooth’s structure. But placing a crown without addressing underlying pulp damage can lead to serious complications. If the crack has exposed or infected the nerve tissue inside the tooth, a root canal is needed to remove that tissue, disinfect the area, and prevent future infection before the crown is applied.
Sometimes, large visible cracks may not require a root canal, while in other cases, small, nearly invisible cracks can have already caused nerve damage. Symptoms like pain when biting, sensitivity to temperature, or swelling may indicate pulp involvement—but some patients experience no symptoms at all.
What Happens If the Crack Is Too Deep?
If the crack extends beneath the gum line or into the root, a root canal may not be enough. In such cases, the tooth may be too compromised to save, and extraction could be the only option. Early diagnosis is key to preserving your natural tooth.
