A dental emergency rarely arrives at a convenient hour. It is usually a knocked-out tooth after a fall, a toothache that has climbed from nagging to unbearable, or a swelling that has appeared overnight. This is the guide to read on your phone in that moment: calm, practical and in order of what matters most.

If you need an emergency dentist right now, the single most important step is to get seen quickly — so keep our number to hand and read on for what to do while you make your way in.

Much of the guidance below reflects how Minesh Popat, a dentist at Smile Hub, approaches urgent care. A significant part of his early career was spent in hospital oral and maxillofacial surgery and out-of-hours services.

“A lot of my career has been in oral surgery and maxfax, which involves A&E work, but we also used to do a lot of 111 emergency work. I have a lot of experience in getting patients out of pain.”

That experience shapes the first rule of any dental emergency: deal with the most serious thing first, not the most obvious one.

First: check for anything more serious than the tooth

A knocked-out or broken tooth is alarming, but it is rarely the most serious injury when there has been an accident, a fall or a blow to the face.

“First of all, if you’ve got your tooth knocked out, try and make sure your other injuries are clear. Obviously, you don’t want any head injuries. All these things need to come first.”

Before you think about the tooth, check for the signs that need urgent medical, not dental, attention:

• Loss of consciousness, confusion, drowsiness, repeated vomiting or a severe headache after a knock to the head.
• Heavy bleeding that will not stop, or a suspected broken jaw or facial bone.
• Difficulty breathing or swallowing, or a rapidly spreading facial swelling — especially one closing an eye or spreading towards the neck.

If any of these apply, this is an A&E situation. Call 999 or go straight to your nearest emergency department. The tooth can wait; these cannot.

Knocked-out or broken tooth: the next 30 minutes

Once you are sure there is no more serious injury, and the situation is genuinely just a tooth that has been knocked out or chipped, act promptly. Time matters most with a whole adult tooth that has come out completely.

1. Find the tooth or the fragment.

“If it’s just a case of the tooth being knocked out or chipped, try and find that fragment.”

2. Handle it by the crown, never the root. Pick it up by the white part you normally see — the crown — and avoid touching the root surface, which carries the delicate cells that help a tooth re-establish itself.

3. If it is dirty, rinse it very gently in milk or briefly under cold water. Do not scrub it, and do not dry it or wrap it in tissue.

4. Store it correctly for the journey. For a knocked-out adult tooth, follow standard first-aid guidance:

• If you feel able to, and it is a permanent adult tooth, gently reposition it back in its socket and bite softly on a clean cloth to hold it in place. Never attempt to reinsert a child’s baby tooth.
• If you cannot reposition it, keep it in a small pot of milk — this is the recommended storage medium and helps protect the tooth on the way in.
• If milk is not available, holding it inside the cheek (between the cheek and gum) so it stays bathed in saliva is an acceptable alternative for an older child or adult who will not swallow it.
• Do not store it in plain water.

5. Get to a dentist as soon as possible. For a knocked-out adult tooth, the sooner it is seen the better the outlook, so treat this as urgent.

“Make your way to a dentist as soon as possible. As long as you explain the situation and the urgency, I’m sure a lot of dental clinics will make the time to see you and squeeze you in for urgent care.”

For a chipped tooth, bring the fragment with you if you can find it — it can sometimes be reattached — but a chip is less time-critical than a whole tooth that has come out.

Severe toothache: how to cope until you’re seen

Severe toothache is your body flagging a problem that will not settle on its own. The goal while you wait for an appointment is to stay as comfortable as possible and get seen quickly.

• Take over-the-counter pain relief as directed on the packet. Always follow the instructions and any warnings, and check with a pharmacist if you are unsure what is suitable for you or take other medication.
• Stay hydrated. Keeping your fluids up helps your body cope while there is an infection or inflammation present.
• Try to keep the area clean. A gentle warm salt-water rinse can be soothing.
• Avoid extremes of hot, cold and very sweet food and drink, which often make the pain spike.

None of this treats the cause — it only buys you time.

“Get down to a dentist as soon as possible for urgent addressing of what is causing you the pain, so that you can make a plan going forward to make sure it doesn’t happen again.”

Dental abscess: don’t sit on it

An abscess is a collection of infection, usually showing up as a bad, throbbing toothache, a tender swelling of the gum or face, a bad taste, or a tooth that is painful to bite on. It is not something to wait out.

Much of the pain comes from pressure: infection builds in a confined space with nowhere to go, and that pressure on the surrounding tissue is what makes an abscess so intensely painful. It will not reliably clear on its own, and it needs professional attention to drain the source and treat the cause.

Book an urgent dental appointment as soon as you can. Seek emergency medical care (A&E or 999) if the swelling is spreading quickly, closing an eye or reaching towards your neck, or if you develop difficulty breathing or swallowing, a fever, or feel generally very unwell — these can be signs the infection is spreading and becoming serious.

Why getting seen quickly matters

The thread running through every dental emergency is the same: the quicker the cause is dealt with, the better the outcome and the sooner you are out of pain. Emergencies are also a chance to stop the same thing happening again — which is why, once the immediate problem is settled, the next step is a proper plan for the underlying cause.

FAQ

How do I find an emergency dentist quickly?
Call the practice, explain clearly that it is an emergency and describe what has happened. Most clinics will do their best to fit an urgent case in on the day. Outside opening hours, NHS 111 can direct you to urgent dental care, and genuine medical emergencies — head injury, breathing difficulty, spreading facial swelling — should go to A&E.

What should I do if my tooth is knocked out?
Check first for any more serious injury. Then find the tooth, handle it by the crown not the root, and either gently place it back in the socket or store it in a small pot of milk (holding it in the cheek in saliva is an alternative if there is no milk). Do not use water. Get to a dentist as soon as possible.

Can I put a knocked-out tooth in milk?
Yes — milk is the recommended storage medium if you cannot reposition the tooth in its socket. It helps protect the tooth on the way to the dentist. Avoid storing it in plain water, and see a dentist urgently.

How do I stop severe toothache at home?
Over-the-counter pain relief taken as directed on the packet, staying hydrated, gentle warm salt-water rinses and avoiding very hot, cold or sweet foods can help you cope. These measures only manage the pain — the cause still needs to be treated, so book an appointment as soon as you can.

Is a dental abscess an emergency?
It needs prompt dental treatment and should not be left. Seek emergency medical care if the swelling is spreading fast, affecting your eye or neck, or you have difficulty breathing or swallowing, a fever, or feel very unwell.
