Just Broke a Tooth? Calm, Practical Steps Until You Are Seen

If a tooth has just broken, start with a few simple steps: rinse gently with warm water, place any pieces of tooth in a small container of milk or your own saliva, hold something cold against your cheek to keep swelling down, and call a dentist as soon as you are able. A broken tooth is rarely dangerous, but unlike bone, a crack in a tooth does not mend itself, so being seen promptly gives you the best chance of keeping the tooth and preventing infection.

The first few minutes

It is unsettling to break a tooth, but what you do straight away can make a real difference by the time you reach us:

• Rinse with warm water, gently, to wash out debris and any small loose pieces.
• Keep the fragment. Store it moist in milk or saliva and bring it along. Occasionally a piece can be bonded back on, and it always helps us see what happened.
• Stop any bleeding. If your gum or lip has been cut, hold clean gauze, or a damp tea bag, firmly against it for around ten minutes.
• Limit swelling by placing a cold compress on the outside of your cheek for short spells.
• Ease the pain with an over-the-counter anti-inflammatory such as ibuprofen, following the label. Never put aspirin on the gum or tooth itself, as it can burn the tissue.
• Protect the area. Chew on the other side, keep to soft foods, and if a sharp edge is catching your tongue or cheek, cover it for now with dental wax or a small piece of sugar-free gum.

Is it an emergency?

Some breaks need to be seen at once, while others can safely wait a day or two. Call straight away if there is bleeding that will not stop, strong pain, swelling in the face or jaw, a fever, or a pink or red dot in the middle of the tooth, which means the pulp, the tooth's inner nerve and blood supply, has been exposed. A tooth that has been loosened or knocked out completely is also urgent. Our dental emergency triage guide explains how to decide between today, tomorrow and the emergency room.

Even a small chip that does not hurt is worth a visit within a few days. Cracks tend to grow, and once one reaches the nerve it can lead to a painful infection or abscess. Breaks vary widely. Fine surface lines in the enamel, known as craze lines, are generally only cosmetic. A lost cusp or a chip above the gum is often simple to repair. A deep crack, a tooth split in two, or a fracture extending below the gumline is much more serious. As it is difficult to tell these apart at home, the safest course is to have us examine it.

How a broken tooth is repaired

The right repair depends on how far the break extends, whether the nerve is involved, and whether the damage continues below the gum. Typical options include:

• Smoothing or bonding for small chips, where tooth-coloured resin rebuilds the missing edge in one appointment.
• A crown for a larger break above the gumline, covering the tooth to protect it and restore comfortable chewing. In many cases this can be done as a same-day crown.
• Root canal treatment followed by a crown when the crack has reached the pulp, removing the damaged tissue before the tooth is sealed and protected. Our endodontics page explains what that involves.
• Removal when the tooth is split or the fracture runs deep below the gum and the tooth cannot be kept. The gap can later be filled with an implant or a bridge.

Encouragingly, many cracked and broken teeth, including some with deep cracks, go on to work comfortably for years after treatment. The cost depends on how involved the repair is, so rather than guess over the phone, we give you a written estimate once we have examined the tooth.

If the whole tooth has come out

A knocked-out permanent tooth is one of the few dental situations where minutes truly count. Results are best when the tooth goes back in within about 30 minutes, and the chances of saving it fall steeply after an hour. Hold the tooth by the crown, never the root. If it is dirty, rinse it briefly without scrubbing or removing any tissue attached to it. If you can, ease it back into its socket and bite gently on gauze to keep it there. If not, keep it moist the whole time, in a cup of milk, between your cheek and gum, or in an ADA-accepted tooth-preservation kit, and do not let it dry out. Then come straight to us or to an emergency room. Baby teeth are different and should not be put back, but a child who loses one this way should still be checked.

Common questions about broken teeth

Does a broken tooth always hurt?

No. Some breaks cause sharp pain on biting or sensitivity to temperature, while others cause no discomfort at all. The absence of pain does not mean the tooth is fine, as a crack may still be creeping toward the nerve.

How quickly should I be seen?

Call immediately for severe pain, swelling, bleeding or a knocked-out tooth. For a painless chip, aim for an appointment within a few days, since cracks only worsen and do not heal.

Can the piece be reattached?

Sometimes. Bring the fragment in milk and we can judge whether it can be bonded back; if not, bonding resin or a crown can rebuild the tooth.

Emergency room or dentist?

For the tooth itself, a dentist. Go to the emergency room first if bleeding cannot be controlled, you may have broken your jaw, you are struggling to breathe or swallow, or there is significant injury to the face.
