A tooth breaks and the first question is always some version of "how bad is this?"
The answer depends on one thing, and it is not how bad it looks in the mirror. It is how much sound tooth structure is left, and where.
Why what remains matters more than what broke off
A tooth handles enormous repeated force. What lets it do that is not the enamel by itself but the way the whole structure works as a shell, with the cusps supported by a continuous ring of tooth around the outside.
Break part of that ring and the mechanics change. Force that used to be distributed now concentrates at the weak point. The remaining structure flexes slightly with every bite, and the crack propagates.
This is why the decision is made on what is left. Two teeth can look equally chipped and need completely different treatment because one lost a corner of enamel and the other lost a supporting wall.
The four situations
Enamel only. A small chip on an edge, no sensitivity, nothing sharp. Enamel has no nerve supply, so this does not hurt. Often smoothed and polished, or built back with composite bonding, a tooth-coloured resin sculpted directly onto the tooth in one visit with no drilling. This is the best-case scenario and it is common on front teeth. More on composite restorations.
Into the dentine. The break has gone past enamel into the softer layer beneath, which is threaded with microscopic tubes running toward the nerve. Now it is sensitive, particularly to cold and air, because those tubes are open to the outside. This needs covering, usually bonding or a filling, and reasonably soon. The tubes are also a route for bacteria.
A cusp broken off, or a large piece. Enough structure is gone that a filling would not survive the force. This is crown territory. A crown wraps the tooth and holds the remaining structure together rather than sitting inside it. Very common in teeth with large old fillings, where there was already less tooth left than it appeared.
Fracture reaching the pulp, or below the gum. If you can see pink or red in the break, that is the pulp exposed, and it needs treating urgently. A root canal saves the tooth if the fracture stops above the bone. If it extends below the bone level, the tooth usually cannot be saved, because there is nothing left to build on and no way to seal it.
That last line is the whole reason for not waiting. A break that is currently above the bone can travel below it.
What to do in the first hour
If a piece broke off, keep it. For front teeth, a clean fragment can sometimes be bonded back on, which gives a better match than any material.
Rinse gently with warm water. No vigorous swishing.
Cover a sharp edge with orthodontic wax or sugar-free gum if it is cutting your tongue or cheek.
Cold on the outside of the face for swelling. Not heat.
Do not chew on it, even if it feels fine. Every bite advances the fracture.
Call us. Do not wait to see whether it settles down, because the version that settles down is usually the one where the nerve died rather than the one that healed.
If a whole adult tooth is knocked out, that is genuinely time-critical. Hold it by the crown, never the root, rinse briefly with milk or saline if it is dirty, and either place it back in the socket or keep it in milk. Get seen immediately. More on what to do in a dental emergency.
When to treat it as urgent
- Pink or red visible in the fracture, meaning exposed pulp
- Severe or throbbing pain, especially worse lying down
- Swelling in the gum, jaw or face
- A break below the gumline
- A whole tooth knocked out
Swelling spreading toward your throat, or any difficulty breathing or swallowing, means the emergency room first. That is not a dental appointment.
If anxiety is the reason you would delay
Say so when you call. We offer sedation, and a broken tooth is a completely reasonable time to use it.
The one thing worth avoiding is letting fear turn a bonding appointment into an extraction, which is what happens when a treatable break is left long enough for the fracture to travel.
What to do
Call and describe two things: whether it is sensitive, and whether you can see anything pink in the break. Those two answers tell us how quickly you need to be seen.
Bring the fragment if you have it.
