It’s usually a Friday night. A tooth gets knocked out at five-a-side, or a dull ache turns into throbbing pain that painkillers won’t touch, and you’re suddenly not sure whether to wait until Monday or find help now. That uncertainty is the hardest part. As an emergency dentist in Hammersmith, we field these calls often, and knowing what actually counts as urgent can save you a tooth or a very long, painful weekend.

Key takeaway

  • A knocked-out adult tooth is a true emergency. Put it back in the socket if you can, or keep it in milk, and see a dentist as fast as possible. Time matters here.
  • Severe swelling that affects breathing or swallowing is a medical emergency, not just a dental one. Go to A&E or call 999.
  • Uncontrolled bleeding, severe pain that painkillers won’t ease, and a spreading facial swelling all need same-day care.
  • A chipped tooth, a lost filling or a crown that’s come off is usually not urgent. It can wait for a normal appointment, though don’t leave it too long.
  • If you can’t reach a dentist, NHS 111 can direct you to urgent care, whether or not you’re registered anywhere.

The ones that can’t wait

Some situations are genuinely time-critical. A knocked-out (avulsed) adult tooth is at the top of the list. The sooner it goes back into place, the better the chance it re-embeds and survives.

Handle it by the crown, the white part you normally see, never the root. If it’s dirty, rinse it gently in milk or saliva, then try to slot it back into the socket the right way round and bite softly on a clean cloth to hold it. Can’t get it back in? Keep it in a cup of milk and get to a dentist. Don’t ever try to reinsert a child’s baby tooth, because you can damage the adult tooth forming underneath. (Source: NHS)

Then there’s infection. A dental abscess can start as “just a toothache” and become serious, so severe swelling, a bad taste, fever or pain that won’t settle needs prompt attention.

FAQ

What should I do if my tooth gets knocked out? Pick it up by the crown, not the root. Rinse it gently in milk or saliva if it’s dirty, try to put it back in the socket, and bite on a clean cloth to hold it. If you can’t reinsert it, store it in milk and get to a dentist straight away. Never reinsert a baby tooth.

Is a dental abscess an emergency? It can be. An abscess is an infection, and if it comes with facial swelling, fever or pain that won’t settle, it needs urgent care. If swelling starts affecting your breathing or swallowing, treat it as a medical emergency and call 999.

I’ve lost a filling, but I’m not in much pain. Is that urgent? Usually not. A lost filling or crown without significant pain or swelling can normally wait for a routine appointment. Try to book within a few days so the tooth doesn’t deteriorate or become sensitive.

Can I get emergency dental care if I’m not registered with a dentist? Yes. Call NHS 111, and they can find you an urgent appointment regardless of whether you’re registered. You can also contact our Hammersmith practice, and we’ll advise on the quickest route to care.

When it’s a hospital job, not a dentist job

This is the distinction people miss. If swelling is spreading towards your eye or down your neck, or it’s making it hard to breathe, swallow or speak, that is beyond what a dental chair is for. Go straight to A&E or call 999. Airway problems from a dental infection are rare, but they are a real medical emergency. (Source: NHS)

A&E doctors aren’t dental specialists and can’t do definitive dental work, so for a lost crown or a cracked tooth without swelling, they’re not the right door.

The ones that feel dramatic but usually aren’t

A front tooth that chips can look alarming in the mirror. Most of the time, it isn’t urgent. The same goes for a filling that falls out or a crown that comes loose. Annoying, sometimes sharp against the tongue, but manageable until you can be seen.

Book in reasonably soon, though. A small chip left alone can turn into a bigger fracture, and an exposed tooth is more prone to decay. Waiting a few days is fine. Waiting a few months often isn’t.

What to do in the moment

Keep it simple. Call your dental practice first and describe what’s happened, because many practices hold slots back for urgent cases. If you’re not registered, or it’s out of hours, use NHS 111 online or by phone, and they’ll point you to an urgent dental service. For pain in the meantime, over-the-counter painkillers taken as directed can take the edge off while you wait.

If something’s happened and you’re not sure how serious it is, call us, and we’ll help you work out the right next step. It’s better to ask than to sit at home worrying about a tooth you might still be able to save.
