Emergency dentist in London at night: what actually exists
There is no walk-in emergency dentistry in London. At 3am with severe toothache there is exactly one route in, it costs £27.90, and A&E is not it.
Severe toothache is one of the few pains that reliably wakes people at 3am, and it arrives with a cruel piece of timing: dental practices are shut, and the internet is full of “24 hour emergency dentist London” adverts that are mostly call-handling services.
Here is what genuinely exists.
Do not go to A&E with a dental problem. Emergency departments are very unlikely to be able to treat it — they have no dentist and no dental equipment. You will wait for hours to be told to ring 111. The exceptions are genuine emergencies: facial swelling affecting your eye, mouth or throat, difficulty breathing or swallowing, or uncontrolled bleeding — those are A&E or 999.
The one route in
NHS 111. That is it. Free, 24 hours a day, seven days a week, by phone or at 111.nhs.uk.
111 assesses the problem and, where appropriate, arranges an urgent dental appointment for you. It may be at a different practice from your usual one, but it is normally nearby.
You do not need to be registered with a dentist. You do not need to have seen one for years. Urgent care is available either way.
What “out of hours” means
Dental out-of-hours is 6.30pm to 8am on weekdays, plus all day at weekends and on bank holidays.
So the 5pm toothache and the 3am toothache go to different places. Before 6.30pm on a weekday, ring your own practice first — most keep emergency slots and will see you faster than any referral route.
What it costs
£27.90 for urgent NHS dental treatment in England, from 1 April 2026. That is the Band 1 charge, and it covers the urgent course of treatment.
It is free if you qualify — by age, pregnancy or recent maternity, certain benefits, or through the NHS Low Income Scheme.
Private emergency dentistry costs considerably more and is not necessarily faster at 3am. Check the NHS route first.
How fast you should be seen
Depending on symptoms, you should be offered urgent treatment within 24 hours or 7 days. Severe pain that keeps you awake and does not respond to painkillers is squarely in the urgent category — say exactly that when you call.
Getting through the night
111 may not get you into a chair before morning. These are the things that actually help in the meantime, and none of them are a cure.
- Painkillers, taken properly. Follow the packet. Paracetamol and ibuprofen can generally be taken together if both are suitable for you — check with 111 or a pharmacist rather than assuming.
- Sleep propped up. Lying flat increases pressure in the tooth and is why toothache is reliably worse at night.
- Cold on the outside of the cheek, not heat. Heat draws more blood to an inflamed area.
- Avoid very hot, very cold and very sweet things. Also avoid chewing on that side.
- Salt water rinse — warm, not hot — can ease a gum problem.
- Do not put aspirin directly on the gum. It burns the tissue. This piece of folk advice refuses to die.
- Do not use a heat pad on your face and do not try to drain a swelling yourself.
The adverts
Search “24 hour emergency dentist London” and the top results are largely booking and call-handling operations, not surgeries with a dentist sitting there at 3am. Some are genuine private practices with an on-call rota. Some are lead generators.
The same rules apply here as to any urgent trade — a real address, a clear price before you commit, and scepticism about anything that advertises 24-hour availability without saying what it costs. That pattern is covered in detail in how to check any UK tradesperson, and the locksmith version of exactly this advertising problem is documented on our sister site, the London Lockout Guide.
Pharmacies
A pharmacist cannot treat a tooth, but they can advise on pain relief and spot the signs that need urgent care. Very few London pharmacies open overnight — the method for finding one that genuinely is open is in finding a 24-hour pharmacy.
The short version
- Facial swelling near eye, mouth or throat, trouble breathing or swallowing, uncontrolled bleeding → 999 or A&E.
- Everything else → 111, any hour, free. They arrange the appointment.
- Not A&E. They cannot treat teeth.
- £27.90, or free if you qualify.
- Weekday before 6.30pm → ring your own practice first.
