Broken or Chipped a Tooth? What to Do Now

Breaking or chipping a tooth usually happens without warning, from biting down on something hard, a knock during sport, or a fall. The first reaction is often panic, especially when it is a front tooth or the edge feels jagged against the tongue. The reassuring part is that most chips and breaks are not true emergencies and can be repaired well once you are seen. What matters in the first hour is protecting the tooth, judging how serious the break is, and keeping any broken piece in case it can be reattached.

What to do in the first hour

The steps below apply whether you have lost a small corner or a larger section of the tooth. They protect the exposed surface and give a dentist the best chance of a clean repair.

• Rinse your mouth gently with warm water to clear away any fragments and see what has happened.
• If a piece has broken off, keep it and store it in milk or your own saliva, not water and not dry in a tissue. A larger fragment, especially from a front tooth, can sometimes be bonded back on for the best cosmetic result.
• Press a clean piece of gauze or a clean cloth on any bleeding gum for around ten minutes without lifting it to check.
• Hold a cold compress against the cheek over the area to ease swelling and pain.
• Cover a sharp or jagged edge with a small piece of orthodontic wax or sugar-free chewing gum so it does not cut your tongue or lip until you are seen.
• Take your usual over-the-counter painkiller as directed on the packet if the tooth is sore.

The advice to keep the broken piece in milk mirrors the rule for a tooth that has come out completely. If the whole tooth has been knocked out rather than chipped, that is a different and more time-critical situation, and a knocked-out adult tooth needs re-implanting within the hour to stand the best chance.

Telling a minor chip from an urgent break

Not every broken tooth needs to be seen the same day. The severity depends on how deep the break goes and whether the inner layers of the tooth are exposed. A tooth has a hard outer enamel layer, a softer dentine layer beneath it, and a living pulp at the centre that holds the nerve and blood supply.

A small chip in the enamel with no pain and no sharp edge is usually cosmetic and can wait a few days for a routine repair. A deeper break becomes more urgent when the dentine is exposed, which typically shows as sensitivity to hot, cold or sweet things. It becomes a same-day matter when the pulp is exposed, which means severe pain and sometimes a visible pink or red dot in the middle of the tooth. A tooth that is loose, pushed out of position, or bleeding from within is also one to have looked at quickly.

There is also the cracked tooth that does not visibly break. Pain that flares when you bite and fades when you release the pressure can point to a crack running into the tooth, which lets bacteria reach the pulp over time. It needs examining even without an obvious chip. The NHS guidance on a chipped, broken or cracked tooth is a useful reference for what a dentist can do, from bonding and fillings to a crown or root canal for a deeper fracture.

What to avoid

• Do not try to file or smooth a sharp edge yourself. You risk weakening the tooth further or cutting your mouth.
• Do not glue the fragment back with household or superglue. It is toxic in the mouth and prevents a proper repair.
• Do not chew on the broken side, which can crack the tooth further or dislodge more of it.
• Do not ignore a painless break for weeks. An exposed surface lets decay and infection set in, turning a simple repair into a bigger treatment.

If the break is causing steady throbbing pain rather than sharp sensitivity, the measures that help with any dental pain apply, and the painkiller combination for managing severe toothache before you can be seen works best while you wait. A break that has taken a filling with it needs the same protection as any lost filling, so the exposed cavity does not deepen.

When a break is a medical emergency

A chipped or broken tooth on its own is a dental problem, not a medical one. It becomes a hospital matter when it comes with a heavier injury: a possible broken jaw, a deep cut that may need stitches, a serious blow to the head, or bleeding you cannot control with steady pressure. In those cases the emergency department at Princess Alexandra Hospital on Hamstel Road in Harlow is the right place, or call 999. Facial swelling that is spreading, or any difficulty swallowing or breathing, is also a 999 or A&E situation rather than something to wait for a dental appointment.

For a child who has broken a tooth, the same rules apply but with less cost pressure, because NHS dental care is free for under-18s. Children's dental emergencies in Harlow bring their own first-aid picture, including chipped teeth and knocks during play.
