Top Reasons to Visit an Emergency Dentist
The situations that genuinely warrant a same-day emergency dental visit, when to go to A&E instead, and what to do at home while you wait to be seen.
Most dental problems can wait until your next appointment. Some genuinely cannot. Knowing the difference — and knowing what to do in the first hour of a real dental emergency — can be the difference between saving a tooth and losing it.
This guide covers the situations that genuinely warrant a same-day emergency dental visit, when to head to A&E instead, and what you can do at home while you wait to be seen. At Confident Smile Dental Practice in Shepperton we keep emergency slots open every working day for our patients — but the more you know beforehand, the better the outcome.
The most common genuine emergencies
Sudden severe toothache
Not a mild sensitivity or a niggle — a pain that stops you sleeping, doesn't respond to painkillers, or is throbbing constantly. This usually means the nerve of a tooth is inflamed or infected, and it's not going to settle on its own. The sooner we see you, the more comfortable we can make you and the more options we have to save the tooth.
Our guide to what toothache actually means walks through the common causes and what each usually indicates.
A knocked-out tooth — time-critical
If an adult permanent tooth is completely knocked out, this is one of the few situations where minutes genuinely matter. Ideally the tooth is back in place within 30–60 minutes for the best chance of saving it.
First aid steps:
- Pick the tooth up by the crown (the white part) — not the root.
- If it's dirty, rinse it briefly in milk or in the patient's own saliva. Do not scrub it, do not use tap water, do not remove any tissue that's attached to the root.
- If you can, gently push the tooth back into its socket the right way round and bite down on a clean cloth to hold it in place.
- If you can't reinsert it, store it in milk (or in the patient's own mouth between cheek and gum for an older child or adult, if that's safe) — never in water.
- Get to a dentist immediately.
For a baby tooth that's been knocked out, do not put it back — call for advice.
A broken or chipped tooth
If the break is small and there's no pain, you can usually wait a day or two for a normal appointment. If it's a large break, exposes the inner tooth, or is painful, it's an emergency. Try to keep any tooth fragments in milk and bring them with you.
Facial or gum swelling
A visible swelling of the gum, face or jaw — particularly if it's growing, hot, or accompanied by fever — needs prompt treatment. Dental infections can occasionally spread rapidly, and swelling near the eye, under the tongue, or affecting breathing or swallowing is an urgent situation.
Lost filling or crown
Not painful in itself, but often uncomfortable or leaving a sharp edge on the tongue. You can be seen next-day in most cases. If a crown has come off cleanly and you can see it isn't damaged, keep it — we can often re-cement the same crown.
Uncontrolled bleeding
Some bleeding after a tooth is knocked out or an extraction is normal. Bleeding that won't stop after 20–30 minutes of firm biting on gauze needs attention.
Broken denture
Not medically urgent, but genuinely disruptive. We can usually see denture wearers same-day or next-day for repairs. Do not try to glue it yourself with household adhesive — it usually makes a professional repair harder.
Dental pain in a child
Children can't always articulate exactly what's happening, and parents often worry — rightly — about whether something is a real emergency. As a general rule, any child with persistent dental pain, swelling or trauma should be seen the same day. We plan child emergency visits calmly and unhurriedly.
When to go to A&E instead of the dentist
Some situations are beyond what any dental practice can handle and need hospital care immediately.
Call 999 or go to A&E if:
- Swelling is affecting breathing or swallowing.
- Swelling has spread to the eye area or is closing an eye.
- You have significant facial trauma with possible jaw fracture.
- Bleeding is uncontrollable despite firm pressure for 30+ minutes.
- Signs of severe infection: high fever, feeling very unwell, spreading redness, difficulty opening the mouth.
Everything else is dental-emergency territory, not A&E.
What to do at home while you wait
Practical comfort measures while waiting for your appointment:
- Painkillers: Paracetamol and/or ibuprofen at the correct dose (as long as you can take these safely) usually help. Follow the packet instructions.
- Cold compress: For swelling, a cold pack (wrapped in a cloth) held against the outside of the face in 15-minute stretches.
- Saltwater rinse: For gum pain or after any trauma, a warm — not hot — saltwater rinse can soothe. Half a teaspoon of salt in a cup of warm water, swished gently.
- Soft foods: Stick to soft, lukewarm foods. Avoid extremes of temperature, which can trigger sharp pain in a sensitive tooth.
- Keep your head elevated at night if there's swelling or throbbing — it often reduces the pounding pain that comes when you lie flat.
- Don't put aspirin directly on a tooth or gum — it doesn't work as a numbing agent and can cause a chemical burn.
- Don't try DIY dentistry — no matter what the internet suggests. Draining swellings, pulling teeth or drilling at home makes the professional treatment harder and dramatically increases the risk of infection.
Managing anxiety in an emergency
Dental anxiety and dental emergencies are a difficult combination. Being in pain, being scared, and having to visit a dentist urgently is genuinely hard. If this describes you, our guide to managing dental anxiety in emergencies has practical steps that help.
At our Shepperton practice we take extra care with anxious patients in an emergency — sedation is available, appointments are unhurried, and everything is explained calmly at every step.

Frequently asked questions
What counts as a real dental emergency? Severe pain that won't settle, a knocked-out or badly broken tooth, uncontrolled bleeding, or facial swelling. Everything else can usually wait 1–2 days.
Can a knocked-out tooth be saved? Often yes, if you act fast. The best window is within 30–60 minutes. Store the tooth in milk (or in the mouth) and get to a dentist immediately.
Should I go to A&E for a toothache? A&E generally can't treat toothache. It's a dental problem and needs a dentist. Go to A&E only if there are signs of a serious infection, difficulty breathing or swallowing, or major trauma.
Can painkillers make a toothache go away? They can dull the pain temporarily. They don't fix the underlying cause. If pain returns as the medication wears off, you need to be seen.
How quickly can Confident Smile see me in an emergency? Same-day for genuine emergencies during working hours. Call as early in the day as possible for the best chance of a morning slot.
What if my child has severe toothache? Call us the same day. We'll fit them in and take the assessment calmly. Give age-appropriate painkillers in the meantime if it's safe to do so.
Is a lost crown an emergency? Not medically urgent, but usually seen within a day or two. Keep the crown safe if you have it — it can often be re-cemented.
