What to Do If Your Tooth Breaks in Half

Broke a tooth in half? Here is exactly what to do right now to ease the pain, protect what is left, and know when it is an emergency.

A tooth that splits in half looks scary, but quick action protects the tooth and gives a dentist the best chance to save it. Here is the short version: rinse with warm water, save any broken pieces in milk, press clean gauze on any bleeding, and cover sharp edges with dental wax. Take ibuprofen for pain and chew on the other side until you are seen. If the break is large, the pain is severe, or you see a red dot in the center of the tooth, call an emergency dentist now at 1-888-771-7431.

First, how bad is the break?

Not every broken tooth is the same. A small chip off the outer enamel is uncomfortable but rarely urgent. A tooth that breaks in half is different, because the crack often reaches the soft inner layers where the nerve lives.

Treat it as an emergency if you see a pink or red dot in the center of the tooth, which is exposed nerve. Other warning signs are sharp pain when you breathe in cold air, bleeding from the tooth itself, or a jagged half that wobbles when you touch it. Any of these means you should call a dentist right away. For more on the different kinds of damage, see our broken tooth guide.

What to do in the first 10 minutes

Rinse with warm water. Swish gently to clean the area and clear away any small fragments. This also helps you see how big the break really is.

Save the broken pieces. Find any pieces that came off, rinse them, and store them in a small cup of milk or in your saliva. A dentist can sometimes bond a clean fragment back on, and milk keeps the piece from drying out on the way to the office.

Stop any bleeding. Press a piece of clean gauze or a damp tea bag against the spot for about 10 minutes. Bleeding from the gum usually slows quickly. Bleeding from inside the tooth needs a dentist.

Bring down swelling. Hold a cold compress against your cheek for 15 minutes at a time. Wrap the ice in a thin towel, and never place ice directly on the tooth.

Cover the sharp edge. A broken half often leaves a jagged edge that cuts your tongue or cheek. Cover it with over-the-counter dental wax, or a piece of sugarless gum in a pinch.

How to manage the pain safely

Ibuprofen (Advil, Motrin) works best for a broken tooth because it brings down swelling as well as pain. Take 400mg with food or water, and follow the label. If the pain is bad, the American Dental Association notes that adding 500mg of acetaminophen (Tylenol) is safe for most adults and often works better than either one alone.

Do not rub aspirin on your gums. People try this all the time, and it burns the soft tissue and makes things worse. Clove oil dabbed on a cotton ball is a gentler option that numbs the area for a while.

When a broken tooth is an emergency

Call an emergency dentist the same day if you have severe or throbbing pain that pain relievers do not touch, bleeding from the tooth that will not stop, a visible exposed nerve, swelling in your face or gums, or a large piece missing below the gum line.

Fast treatment is not just about comfort. An open tooth lets bacteria reach the nerve, which can turn into an infection or abscess within days. If you already have facial swelling along with a fever or trouble swallowing, treat it as a medical emergency and call 911.

Can a tooth broken in half be saved?

Often, yes. The fix depends on how deep the break goes. For smaller breaks, a dentist rebuilds the tooth with tooth-colored bonding resin. If a large part is gone but the root is healthy, a crown caps and protects the tooth. If the break reaches the nerve, a root canal removes the damaged pulp before a crown goes on. Extraction is a last resort, used only when the tooth is broken too far below the gum to repair.

The sooner you are seen, the more of these options stay open to you. That is why saving the pieces and calling quickly matters so much.

Frequently asked questions

Is a tooth broken in half a dental emergency?

Usually yes. A deep break can expose the nerve and let in infection. Call an emergency dentist the same day, especially if you have pain, bleeding, or swelling.

Can the dentist put the broken piece back on?

Sometimes. If you save the piece in milk and get there quickly, the dentist may bond it back. If not, bonding resin or a crown rebuilds the tooth.

What if my broken tooth does not hurt?

No pain is good news, but still see a dentist soon. The inner tooth can be exposed without hurting at first, then become infected later.

How much does it cost to fix a tooth broken in half?

It depends on the repair. Bonding costs less than a crown, and a root canal adds to the total. Many offices offer payment plans, so ask when you call.
