Cracked or Chipped Tooth: What to Do Right Now

In short: For a knocked-out adult tooth: hold it by the crown, never scrub it, reseat it in the socket if you can or store it in milk, and reach a dentist within the hour. For chips, keep the fragment and cover sharp edges. A painless crack still needs seeing — cracks extend until they reach the nerve.

Teeth chip and crack from falls, sport, biting something hard, and from grinding weakening them over years. What to do depends on how bad it is — and in one case, on how fast you act.

If a tooth has been knocked out completely

This is time-critical, and doing the right thing in the first hour matters more than anything a dentist can do later.

1. Pick it up by the crown — the chewing part — never the root.
2. Do not scrub it. If dirty, rinse briefly in milk or saline. Not water, and never with soap or disinfectant.
3. Try to reposition it in the socket straight away and bite gently on a clean cloth to hold it.
4. If you cannot, keep it in milk. Milk is the best readily available storage medium. Saliva works; plain water does not and damages the root surface cells.
5. Get to a dentist immediately. The best outcomes come within the first 30 to 60 minutes.

Baby teeth are not re-implanted — doing so can damage the adult tooth developing above. Still see a dentist.

If it is chipped or cracked

• Rinse with warm water
• Cold compress on the outside of the face for swelling
• Keep any broken fragment — sometimes it can be bonded back
• Cover a sharp edge with orthodontic wax or sugar-free gum to protect your tongue and cheek
• Eat soft food and avoid chewing on that side
• Painkillers as directed on the packet

Treatment by severity

Minor chip in enamel. Often smoothed, or restored with composite bonding in a single visit.

Larger chip. Composite build-up, or a veneer or crown depending on how much is missing.

Crack reaching the nerve. Usually needs a root canal followed by a crown.

Crack extending below the gum into the root. Often not restorable, and the tooth may need extraction.

Why a painless crack still needs seeing

Cracks propagate. A hairline crack that does not hurt today can extend under normal chewing until it reaches the nerve or splits the tooth. Caught early it is often a simple restoration; caught late it can mean losing the tooth. The classic warning sign is a sharp pain when biting down or, distinctively, when releasing the bite.

If you grind your teeth, cracks recur until the grinding is addressed — see teeth grinding.
