It is ten o'clock at night and a tooth that grumbled for a fortnight has decided to make its point. Every practice within twenty miles closed hours ago. The internet offers you two unhelpful poles: ride it out with painkillers, or sit in A&E behind people with broken bones. Neither is quite right.

The route that exists for exactly this situation is NHS 111. Call or use it online, describe the problem, and it can book or direct you into urgent dental services in your area, including out-of-hours clinics you would struggle to find on your own. You do not need to be registered anywhere or to have seen a dentist in years. Urgent dental care is one of the few parts of the system where being nobody's patient does not count against you.

What counts as urgent, and what can wait until morning

Broadly, swelling that is spreading into your face or neck, bleeding that will not stop, or an injury that has knocked a tooth out or broken your jaw are the situations that justify urgent care tonight, and a swelling that affects your breathing or swallowing is an A&E matter. Bad pain with none of those features is miserable but usually safe to manage overnight with the painkillers you would normally take, following the packet. That is general guidance, not a diagnosis down a phone line: if you are worried, let 111 make the call, because triage is precisely what it is for.

The morning-after phone call

If you get through the night, ring practices at opening time, not mid-morning. Many keep a few same-day slots for emergencies and hand them out to the first callers. Say the words 'emergency appointment' rather than describing symptoms at length; receptionists triage all day and the phrase moves you into the right queue. Your own practice, if you have one, should see you quickly. If you do not have one, ask any practice about emergency slots for new patients. Plenty offer them, privately if their NHS book is full, and they will tell you the fee before you commit.

Finding the practices to ring

The ring-round is easier with a list in front of you. Among the 3,025 dental practices listed on this site you can pull up practices near you with phone numbers in one place, which matters at 8.29am when you want to be first in three queues at once. If the tooth needs proper work rather than a rescue, you can also set out what has happened and get quotes for the treatment once the pain is handled.

And when the emergency is over, book the check-up. The tooth that erupts at ten o'clock at night almost always sent a warning weeks earlier, at a far more civilised hour.
