Dental problems rarely happen at a convenient time. This guide explains what counts as an emergency, what you can do straight away, and how to find a London practice that can see you quickly.
Is it a dental emergency?
You should try to be seen the same day or next day if you have:
- Severe toothache that painkillers are not controlling
- A knocked-out or badly broken tooth
- Swelling in your face, gum or jaw
- Bleeding that will not stop after an extraction
- A lost filling or crown that is causing pain
When to go to A&E instead
Go to A&E or call 999 if swelling is affecting your breathing, swallowing or vision, if bleeding is heavy and will not stop, or if you have had a serious injury to your face or head. For urgent advice out of hours you can also call NHS 111.
What to do right now
- Knocked-out adult tooth: hold it by the crown, not the root. Follow NHS knocked-out tooth guidance and seek dental help urgently. Never put a knocked-out baby tooth back in.
- Broken tooth: rinse your mouth with warm water and keep any pieces.
- Toothache: take painkillers as directed on the packet and avoid very hot, cold or sugary food.
- Swelling: use a cold compress on the outside of your face.
How to find an appointment today in London
Contact a dentist and explain your symptoms. If you cannot get help, use NHS 111 online or call 111 for advice about urgent dental services. On SmileQuick, check practices offering emergency care and their opening hours; some publish appointment times, but you must confirm suitability and availability directly before travelling. An online slot may be private, not NHS.

Can I see a private dentist for an emergency without being registered?
Some private practices offer emergency appointments to new patients. Phone first to explain your symptoms, confirm availability and ask what the appointment includes.
What if it is the weekend?
Some London practices open on Saturdays. Check opening hours on each practice profile, or call NHS 111 for urgent out-of-hours advice.
This guide is general information, not medical advice. Always follow your dentist's advice.
