Symptom Guide
Cracked Tooth
A crack is the one dental symptom where waiting genuinely costs you options. Here is what to do in the next hour, and what happens after.

How teeth crack in the first place
- A hard bite on the wrong thing. Popcorn kernels, olive pits, ice, and the occasional surprise in a sandwich account for a lot of cracked molars.
- A large, older filling. Big fillings leave thin walls of natural tooth around them, and after years of chewing those walls can give way.
- Grinding and clenching. Overnight force, multiplied across thousands of nights, fatigues teeth the way bending fatigues a paperclip.
- An impact. Sports, falls, and elbows happen. A custom sports mouthguard is cheap insurance if impacts are part of your hobbies.
Self-care in the next few hours
Rinse with warm water, save any broken piece, and move chewing to the other side. If an edge is shredding your tongue or cheek, a bit of orthodontic wax or even sugar-free gum pressed over the sharp point protects the soft tissue until your visit. Ibuprofen handles most crack-related soreness. Skip very hot, very cold, and very chewy foods; a cracked tooth dislikes all three.
When to call promptly
Every crack deserves a call, but call the same day if there is sharp pain on biting, lingering temperature sensitivity, swelling, or a piece missing large enough to expose a darker layer inside the tooth. Those signs mean the crack is close to, or into, the nerve. For step-by-step urgent guidance, see our broken tooth repair page.
How we evaluate and repair cracks
Cracks hide from flat X-rays, so we combine magnified exam, bite testing, and CBCT 3D imaging, available at both offices, to map how deep one runs. Shallow chips are often fixed the same visit with bonding. Cracks that weaken a cusp do better with an onlay or a full crown that holds the tooth together. If the nerve has been reached, an in-house non-surgical root canal saves the tooth, and nitrous oxide is available throughout if you want the edge taken off.

Frequently Asked Questions
My tooth cracked but does not hurt. Do I still need to come in?+
Yes, and sooner beats later. A painless crack is a crack caught early, which is the best kind. Cracks only travel in one direction, deeper, and a tooth that could have been saved with a crown can become one that needs a root canal or an extraction if the crack reaches the root. A quick exam tells us how far it goes.
Should I save the piece that broke off?+
Yes. Rinse it, keep it in a small container, and bring it with you. Sometimes a fragment can be bonded back; even when it cannot, seeing the piece helps us understand how the tooth failed and what will protect it best.
Why does my cracked tooth only hurt when I release a bite?+
That release-pain pattern is the classic signature of a cracked tooth. Biting flexes the crack open slightly; letting go snaps it shut, and that movement irritates the nerve inside. It is useful information, so mention it when you call.
Can a cracked tooth heal on its own?+
No. Unlike bone, tooth structure has no way to knit itself back together. What feels like healing is usually the nerve quieting temporarily. The structural weakness stays, which is why we recommend evaluating every crack even if the discomfort fades.
