Dental Trauma: What to Do If You Break or Knock Out a Tooth
If you or your child has just knocked out or broken a tooth in Gosforth, Newcastle or anywhere nearby, the single most useful thing to know is this: for a knocked-out adult tooth, speed and how you handle the tooth itself can be the difference between saving it and losing it permanently.
This guide covers what to do in the first few minutes after any dental trauma, whether that's a knocked-out tooth, a break, or a loose tooth. For deeper guidance on recovery and treatment once the emergency's been handled, see the linked guides at the end of this page.
If an Adult Tooth Has Been Completely Knocked Out
This is a genuine dental emergency. According to Dental Trauma UK, the steps are:
- Pick the tooth up by the crown only, the white, visible part. Never touch or handle the root.
- Clean it gently. Lick it clean if it's dirty, or rinse briefly in water. Don't scrub it or use soap.
- Try to put it straight back in its socket, facing the right way, and bite gently on a clean handkerchief or cloth to hold it in place.
- Go straight to a dentist, whether or not reinsertion worked.
- If you can't get it back in the socket, don't let it dry out. Place it in a container of milk, not water, and get to a dentist or, out of hours, A&E, immediately.
Time genuinely matters here. The faster a knocked-out tooth is reinserted or properly stored, the better its chances of survival. This guidance is specifically for adult, permanent teeth. Never attempt to reinsert a knocked-out baby tooth, since doing so can damage the developing adult tooth underneath.
If a Tooth Is Chipped or Broken
- Try to find the broken piece; if there is one, it may be possible to bond it back.
- Put it in milk or saliva (by spitting into a container if it's your tooth, or having your child spit into a container if it's theirs) and take it to a dentist.
- Rinse your mouth gently with warm water.
- Apply a cold compress to your face if there's any swelling.
- See a dentist as soon as possible. Depending on the extent of the damage, treatment may involve reattaching the fragment or building the tooth back up with a tooth-coloured filling. See Crowns vs Veneers: Understanding the Difference if the damage is more significant and a crown might be needed instead.
Don't assume a small chip is nothing to worry about. Even minor fractures can expose sensitive inner layers of the tooth or create a weak point that worsens over time if left unassessed.
If a Tooth Feels Loose but Hasn't Come Out
A tooth that's been knocked and now feels loose or out of position, without being fully knocked out, still needs urgent assessment. Don't wiggle it or try to reposition it yourself. Avoid biting on it, and get to a dentist as soon as possible so it can be checked, and splinted if necessary while it's still viable.
Why "Straight Away" Isn't an Exaggeration
For a knocked-out tooth specifically, the window in which reinsertion is likely to succeed is genuinely narrow. That's why the advice above emphasises immediate action over waiting to see how you feel or fitting it around your day. If it happens during opening hours, call us straight away. Out of hours, your nearest A&E or emergency dental service is the right call rather than waiting until the next working day.
What Happens Once You're Seen?
Treatment depends entirely on what's happened. A reinserted tooth typically needs splinting while it stabilises, and broken teeth are treated according to how much structure is affected. We've written a full breakdown of what recovery actually looks like in the linked guide below.

Frequently Asked Questions
Should I go to A&E or a dentist for a knocked-out tooth?
A dentist, if you can reach one quickly. Call ahead so they know you're coming. Out of hours, A&E can help if no emergency dental service is available, but don't delay either way.
Can a knocked-out tooth always be saved?
Not always, but handling it correctly, by the crown, kept moist, reinserted or stored in milk, and seen urgently, gives it the best possible chance.
What if it's a child's baby tooth that's been knocked out?
Don't try to reinsert a baby tooth. This can damage the permanent tooth developing underneath. Still get your child seen promptly. See Bringing Your Child to the Dentist: What to Expect for more on making dental visits easier for kids.
What if I can't get to a dentist straight away?
Follow the immediate steps above regardless; insert or store the tooth in milk, and get seen as soon as you possibly can. Out of hours, A&E or an emergency dental service is the right call rather than waiting.
Does a knocked-out or badly damaged tooth always need root canal treatment?
Not always, but it's common, since the injury can affect the nerve inside the tooth even when the tooth itself is saved. Your dentist will monitor this over the following weeks as part of your recovery.
