How to Handle a Dental Emergency at Home What to Do Before You See a Dentist
Emergencies never happen at a convenient time.
One moment you're enjoying Sunday dinner. Next, a crack—cold shock before pain hits.
Maybe it's your child—tumbling, returning in tears, tooth in hand.
Or you wake at 2 am, jaw throbbing, nothing brings relief, and you wonder what to do.
Prompt action in a dental emergency can mean the difference between saving and losing a tooth.
This guide offers clear, practical, dentist-approved advice for common emergencies—so you know what to do when it happens to you or a loved one.
Before Anything Else — Know When It Is a True Emergency
Not every dental issue requires urgent action, but some conditions are genuine emergencies. Identifying true emergencies helps you determine if you need immediate dental care, such as a same-day appointment or hospital visit. Emergencies generally involve severe pain, swelling, uncontrolled bleeding, or a threat to breathing and swallowing.
Call your dentist or NHS 111 today if you have:
- ✔ A tooth that has been completely knocked out
- ✔ Severe, unrelenting pain that over-the-counter painkillers simply do not manage
- ✔ A swollen jaw, cheek, or neck — especially if it came on quickly
- ✔ Difficulty breathing or swallowing alongside dental pain
- ✔ Bleeding from the mouth that has not slowed after 20 minutes of pressure
- ✔ Signs of a dental abscess — throbbing pain, fever, foul taste, pus
It can wait two to three days if you have:
- – A small chip or crack with no pain at all
- – A lost filling causing only mild sensitivity
- – A broken denture that is not cutting your mouth
- – A loose crown with no underlying pain
If you are unsure whether your dental issue is an emergency, call your dental practice for guidance. True emergencies typically involve severe pain, swelling, uncontrolled bleeding, or difficulty with breathing or swallowing. It is always better to check than to delay help for a serious condition.
1. Knocked-Out Tooth — You Have About 60 Minutes
A tooth knocked completely out — what dentists call an avulsed tooth — is the most time-critical dental emergency. The survival window is roughly 60 minutes; after that, chances of successful reimplantation drop dramatically.
If you act quickly and correctly, your dentist may be able to save the tooth. Knowing what to do immediately matters hugely.
Step one — pick it up correctly. Only ever handle the tooth by the crown — the white part you bite with. The root is covered by a microscopic layer of periodontal ligament cells, which are essential for the tooth to reattach. Touch the root, and you risk killing those cells before you even get to the surgery.
Step two — clean it if needed. If the tooth is visibly dirty, rinse it very briefly — ten seconds at most — under cold water or, better still, in a small amount of full-fat milk. Do not scrub it, do not use soap, and under no circumstances wrap it in a tissue or kitchen roll. Dry tissue is one of the worst places you can store a tooth.
Step three — put it back if you possibly can. This sounds frightening, but it is the single best thing you can do. Gently push the tooth back into its socket, making sure it is facing the right way, and bite down softly on a clean piece of gauze or cloth to hold it there. The socket is by far the best storage environment for that tooth.
If you cannot put it back — perhaps because it is a young child's tooth that is distressed, or the socket is badly damaged — store the tooth in full-fat milk. If milk is not available, the person can tuck the tooth between their cheek and gum (adults only — a child could swallow it). Do not store it in water.
Then get to a dentist or A&E immediately. Ring ahead so they are ready for you.
⚠️ One final note: this advice applies only to permanent adult teeth. If a child loses a baby tooth through trauma, do not try to reimplant it. Baby tooth roots sit very close to the developing adult teeth beneath them, and reimplantation can cause serious damage to the unerupted adult tooth.
2. Severe Toothache — How to Get Through the Night
The toothache is relentless. It disrupts sleep, eating, and thinking, often at the worst times.
Home remedies will not cure whatever is causing the pain — that requires professional diagnosis and treatment. But they can make the hours until your appointment considerably more bearable.
Pain relief: Ibuprofen tends to be more effective for dental pain than paracetamol alone because tooth pain is largely driven by inflammation, and ibuprofen is an anti-inflammatory. If you can take ibuprofen safely, take it as directed. If not, paracetamol will still help take the edge off. Never exceed the recommended dose, and never take both together unless a pharmacist or clinician has specifically told you that it is safe to do so.
Clove oil is the only proven home remedy. Dab a small amount on the tooth and gum. Use sparingly — too much irritates.
Saltwater rinse: Dissolve half a teaspoon of table salt in a glass of warm water, then rinse gently for 30 seconds. It will not significantly numb the pain, but it reduces bacterial activity in the mouth, keeps the area clean, and provides mild, soothing relief.
What you must not do: Never place aspirin against the gum near a painful tooth. This outdated remedy causes chemical burns. It does not relieve dental pain — just creates another problem.
When a toothache becomes a medical emergency: If your toothache is accompanied by significant facial swelling, a high temperature, swollen neck glands, or difficulty breathing or swallowing, do not wait for a dental appointment. These are signs of a spreading infection, and you need to go to A&E or call 999. A dental infection that spreads into the jaw or neck can become genuinely life-threatening within hours.
Tooth fractures can also occur suddenly. Let's walk through how to assess and respond to a broken or chipped tooth.
3. Broken or Cracked Tooth
When you break a tooth, stay calm and assess the situation.
Minor chip, no pain: Rinse with warm water, run your tongue over the area, and call your dentist for a routine appointment within the next few days. This is not an emergency.
Larger break, sharp edge: Use dental wax from the pharmacy to cover the edge and protect your mouth. Rinse with salt water. Book an urgent appointment.
Break with significant pain or sensitivity: If the break has gone deep enough to expose the inner layers of the tooth, you will know because the sensitivity will be intense — this needs to be seen today or tomorrow. The exposed dentine and potentially the pulp (the nerve and blood vessels inside the tooth) are now vulnerable to bacterial infection, temperature changes, and pressure.
If you find the broken piece: Keep it. Store it in milk and bring it to your appointment. It cannot always be bonded back on, but occasionally it can, and it helps your dentist to see exactly how the tooth fractured.
4. Lost Filling or Crown — Temporary Fixes That Actually Help
Losing a filling or crown is unpleasant and sensitive, but only severe pain is a true emergency.
Head to your nearest pharmacy and pick up a temporary dental repair kit. In the UK, brands like Dentemp and Toofypegs are widely available and genuinely effective as short-term solutions. They allow you to seal an exposed cavity or temporarily re-cement a crown at home while you wait for your appointment.
For a lost crown specifically:
- Clean the inside of the crown carefully
- Apply a small amount of temporary cement
- Gently press the crown back into place
- Bite down lightly to seat it properly. Avoid chewing on that side until you have been seen.
⚠️ Do not leave an exposed crown preparation uncovered for more than a day or two. The prepared tooth underneath is not designed to function without its crown, and teeth can shift position surprisingly quickly — potentially making the crown impossible to refit later without additional work.
5. Dental Abscess — The One You Should Never Ignore
A dental abscess is a bacterial infection, and it is the dental emergency that people most dangerously underestimate.
Signs of a dental abscess include:
- ● A severe, persistent, throbbing toothache
- ● Swelling in the face, cheek, or jaw
- ● A small pimple-like bump on the gum near the painful tooth
- ● A foul or bitter taste in your mouth
- ● Sensitivity to heat and cold
- ● Fever and a general feeling of being unwell
Warm saltwater rinses can provide temporary relief and help draw the infection to the surface. But let's be completely clear: a dental abscess cannot be treated at home. It requires antibiotics from a dentist or doctor, and almost always professional drainage of the infection.
Leaving an abscess untreated does not mean it will go away on its own. It will spread into the jawbone, potentially into the neck, and in the most serious cases into the airway. Every year in the UK, people are admitted to hospital with spreading dental infections that began as a toothache that was "managed" at home for too long.
If your face is visibly swollen, your temperature exceeds 38°C, or you have any trouble breathing or swallowing, skip calling a dentist and go directly to A&E or call 999.
6. Mouth Injuries and Soft Tissue Bleeding
The mouth bleeds heavily due to its rich blood supply. Most cuts look worse than they are.
To stop the bleeding:
Rinse the wound briefly with cold water to see it clearly. Then apply firm, continuous pressure with a clean piece of gauze or a folded clean cloth for a full 10 to 15 minutes without lifting it to check. Lifting and re-applying repeatedly is one of the main reasons mouth wounds take so long to stop bleeding. A cold compress against the outside of the mouth or cheek helps reduce swelling.
Go to A&E if:
- ✗ Bleeding has not slowed at all after 20 minutes of steady pressure.
- ✗ The cut is deep, wide, or clearly gaping.
- ✗ The tongue injury appears severe.
- ✗ The person is a young child, and you are concerned.
Getting Help in the UK — Your Options
During surgery hours: Call your dental practice directly. Always the first and best option.
Out of hours: Call NHS 111 (free, 24 hours). They will assess your situation and direct you to an emergency dentist in your area. The NHS 111 service is specifically equipped to handle dental emergencies outside of normal working hours.
A&E: Reserve this for genuine medical emergencies — spreading infection, uncontrolled bleeding, difficulty breathing, suspected jaw fracture.
Walk-in centres: Some NHS urgent treatment centres can prescribe antibiotics for dental infections, even if they cannot perform dental procedures. Worth knowing if you are in significant pain over the weekend.
A Word on Prevention
We know — you have heard this a thousand times. But it is worth saying clearly: the vast majority of dental emergencies are either entirely preventable or, when caught early, are minor procedures rather than crises.
Regular check-ups — ideally every six months — give your dentist the chance to spot a weakening tooth, a failing old filling, or the very early stages of infection before any of them become a problem that wakes you up at 3 am. A small cavity treated today takes 20 minutes. The same cavity left for another year might become a root canal, an extraction, or worse.
If you or your children play contact sports, please ask us about custom-fitted mouthguards. The difference in protection between a properly fitted mouthguard and a cheap over-the-counter tray is significant — and far less expensive than replacing a tooth.

Frequently Asked Questions
Q: Can I go to A&E for a dental emergency in the UK?
A&E can help with spreading dental infections, jaw injuries, and uncontrolled bleeding — but they cannot perform dental procedures. For most dental emergencies, NHS 111 is the better first call as they can direct you to an emergency dentist.
Q: Will NHS 111 find me an emergency dentist?
Yes. NHS 111 has a dedicated dental triage pathway and can locate and book emergency dental appointments in your area, including outside normal working hours.
Q: What is the best painkiller for a toothache?
Ibuprofen (400mg) tends to work better than paracetamol for most toothaches because it reduces both pain and inflammation. If you cannot take ibuprofen, paracetamol is the next best option. Always follow the dosage instructions.
Q: How do I know if my toothache is an abscess?
Abscess pain is typically severe, constant, and throbbing. It is often accompanied by facial or gum swelling, a foul taste, fever, and sometimes a visible pimple-like bump on the gum. If you suspect an abscess, contact a dentist or NHS 111 today.
Q: Can a knocked-out tooth be saved?
Yes — if you act quickly. Pick it up by the crown only, store it in milk or return it to the socket, and get to a dentist within 60 minutes. Time is genuinely critical here.
