Is My Tooth Cracked?

A cracked tooth usually announces itself with sharp pain when you bite down and release, or a new zing with cold. Cracks never heal on their own, so a prompt exam protects the tooth before the crack spreads. This page is general guidance, not a diagnosis; call 540-342-8781 for advice about your own tooth.

Common causes of cracked and chipped teeth

Teeth are remarkably strong, but they take a lifetime of punishment. Cracks usually come from:

  • Biting something hard. Ice, popcorn kernels, olive pits, and hard candy are the classic offenders.
  • Nighttime grinding and clenching. Years of pressure fatigue the enamel until a crack finally opens.
  • Large old fillings. A tooth that is more filling than tooth has thin walls that can flex and split.
  • An accident or a blow to the mouth. Sports, falls, and car doors do not discriminate.
  • Temperature extremes. Chewing ice and then sipping hot coffee stresses enamel the way a hot glass cracks under cold water.

What you can do at home today

If a piece broke off, rinse with warm water and save the fragment in milk or water; sometimes it can be reattached. Cover any sharp edge with dental wax from the pharmacy, or in a pinch, a bit of sugar-free gum, to protect your tongue and cheek. Chew on the other side, skip very hot and very cold foods, and take ibuprofen as directed on the label if the tooth aches. What you should not do is wait to see whether it settles down. A crack that stops hurting has not stopped spreading.

Call the same day if you notice these signs

Call us the same day for pain when biting, a visible crack or missing piece, sensitivity that lingers after hot or cold, or bleeding from the tooth. Those signs mean the crack may be approaching the nerve. If you develop facial swelling, fever, or any trouble swallowing or breathing, that is an emergency; go to the emergency room right away and call us after. For a tooth that broke in an accident, our broken tooth repair page covers exactly what to do in the first hour.

How we treat a cracked tooth at our office

Dr. Chaudhry starts by finding the crack: a careful exam, bite testing tooth by tooth, and an X-ray to see how deep it runs. Small chips are often smoothed or repaired the same visit with cosmetic bonding. A deeper crack usually needs a crown to hold the tooth together, and if the crack has reached the nerve, root canal therapy saves the tooth before the crown goes on. You will always know the plan and the cost before we begin.

Preventing the next crack

Most cracked teeth are preventable. Do not chew ice or hard candy, and keep pens and fingernails out of your mouth. If you wake with a sore jaw or your teeth look flatter than they used to, ask us about a nightguard, because grinding is the quiet force behind many cracks. If you play contact sports, a custom sports mouthguard is far cheaper than the crown it prevents.

Cracked tooth questions we hear most

How do I know if my tooth is cracked?+

The classic sign is a sharp zing when you bite down and release, often with sensitivity to cold. Many cracks are too fine to see in a mirror and can even hide from X-rays, which is why we test bite pressure tooth by tooth at your exam to find exactly which one is flexing.

Can a cracked tooth heal on its own?+

No. Unlike bone, tooth enamel has no living cells that can knit a crack back together. Chewing keeps flexing the crack, so untreated cracks tend to spread deeper over time. The earlier a crack is stabilized, usually with a crown, the better the odds of keeping the tooth for life.

Is a chipped tooth an emergency?+

A small chip with no pain can usually wait a few days for an appointment, though covering any sharp edge helps. A crack with pain on biting, lingering temperature sensitivity, or a piece of tooth that broke off deserves a same-day call so we can protect the nerve before things get worse.

What should I do if a piece of my tooth breaks off?+

Rinse your mouth with warm water, save the fragment in milk or water if you can, and cover any sharp edge with dental wax or sugar-free gum. Take ibuprofen as directed if it aches, avoid chewing on that side, and call us the same day at 540-342-8781.

Will a cracked tooth always need a crown?+

Not always. A tiny chip may only need smoothing or cosmetic bonding, while a crack into the body of the tooth usually needs a crown to hold it together. If the crack reaches the nerve, root canal therapy saves the tooth first. The exam tells us which path fits your tooth.

A crack caught early is a tooth saved

No insurance? No problem. The Virginia Dental Club makes repairs affordable, so a cracked tooth never has to wait on a budget.
