Tooth Broke in Half? What to Do Right Now

If your tooth broke in half, rinse your mouth gently, save any piece you can find, control bleeding with clean gauze, and call a dentist the same day. A tooth that splits this far often has damage close to the nerve, so fast care gives you the best chance of saving it. Do not try to glue the piece back yourself, and avoid chewing on that side until you are seen.

Key Takeaways

• Save the broken piece in milk or a clean container if you can.
• Rinse with warm water and use a cold compress for swelling.
• A tooth broken in half usually needs a crown, and sometimes a root canal.
• If the split goes below the gum line, removal may be the safer choice.
• Same-day care improves the odds of keeping the tooth.

What to Do in the First Hour

1. Rinse your mouth with warm water to clear debris.
2. Find the broken piece, rinse it lightly, and keep it in a small container of milk.
3. Press clean gauze on any bleeding area for about ten minutes.
4. Hold a cold compress on your cheek to reduce swelling.
5. Call a dentist and explain that a tooth has broken in half.

Why Teeth Break in Half

Back teeth take most of the force when you chew, so molars are the most common teeth to split. Common causes include biting on something hard, an old large filling that has weakened the tooth, decay, grinding, and a fall or sports injury. Sometimes a small crack has been growing for months before the tooth finally gives way. You can learn more about common tooth problems on MedlinePlus.

Can a Tooth That Broke in Half Be Saved?

Often, yes. It depends on where the break is and whether the root is healthy. A dentist will look at the tooth and usually take an X-ray to check how deep the damage goes.

• Break above the gum line, nerve not exposed: a crown can cover and protect what is left of the tooth.
• Break reaches the nerve: a root canal followed by a crown may save the tooth.
• Split runs down into the root: the tooth may not be restorable.

When the nerve is exposed, our article on whether you can get a root canal on a broken tooth explains this step in more detail.

If a tooth cannot be saved, the dentist will talk about removal and replacement options. Our guide on what happens when a tooth is completely broken covers that path. You can compare every repair option on our broken tooth repair page.

What to Avoid

• Do not chew on the broken side.
• Do not use super glue or household adhesives on a tooth.
• Do not place aspirin directly on the gum, since it can burn the tissue.
• Do not wait for the pain to settle before calling. Pain can fade even as damage gets worse.

Does It Hurt?

A tooth that broke in half may hurt a lot or barely at all. Pain depends on whether the nerve is exposed. Either way, the remaining tooth is weak and can break further. If pain is your main worry right now, our article on broken tooth pain explains what different kinds of pain can mean.

Frequently Asked Questions

Is a tooth broken in half an emergency?

Yes, it is best treated as one. A deep break can expose the nerve and raise the risk of infection, so try to see a dentist the same day.

Can the broken half be glued back on?

Sometimes a dentist can bond a clean fragment back in place, which is why saving it helps. Never try to glue it yourself.

What if a broken molar does not hurt?

A painless break still leaves the tooth weaker and open to decay. It should be checked soon, even if it feels fine.

How is a tooth that broke in half usually fixed?

Most are repaired with a crown. If the nerve is involved, a root canal may come first. A split into the root may mean the tooth needs to be removed.
