Dental Emergencies: What to Do Before You Reach the Dentist

Dental emergencies rarely happen at a convenient time. A fall on the playground, a bite into an olive pit, or a toothache that suddenly swells your cheek can leave you wondering whether to wait, call a dentist or go to the hospital. This guide explains first steps for the most common situations. It is general information, not a diagnosis: when in doubt, contact a dentist promptly, and for severe symptoms go to an emergency room or call your local emergency number.

Go to the emergency room or call 911 if...

Some symptoms can signal a spreading infection or a serious injury that needs hospital care, not just a dental appointment:

• Swelling of the face, jaw or neck that is spreading, especially toward the eye or down the neck.
• Difficulty breathing, swallowing or opening your mouth.
• Fever with facial swelling, or feeling very unwell.
• Bleeding from the mouth that does not slow after about 15 minutes of firm pressure.
• A possible broken jaw, a jaw that will not close properly, or a head injury, loss of consciousness, confusion or vomiting after a blow.

Hospital teams can manage airway problems, severe infection and facial fractures, and they can arrange follow-up with a dentist or oral surgeon.

Knocked-out adult tooth: minutes matter

A permanent tooth that has been knocked out has the best chance of being saved if it is put back in its socket quickly, ideally within the first hour and sooner is better. Steps commonly recommended by dental trauma guidelines:

1. Find the tooth and hold it by the crown (the white chewing part), not the root.
2. If it is dirty, rinse it briefly with milk, saline or cold water for a few seconds. Do not scrub it, dry it or wrap it in tissue.
3. Try to put it back in the socket, facing the right way, if the person is alert and it goes in easily. Bite gently on a clean cloth to hold it.
4. If you cannot replant it, keep it moist: in a small container of milk, in saline, or in the person's own saliva (for example, in the cheek of an adult who will not swallow it). Plain water is not ideal for longer storage.
5. See a dentist immediately. Call ahead so they are ready.

Do not replant a knocked-out baby tooth. Pushing it back can damage the adult tooth developing underneath. Keep the child comfortable, control bleeding with gentle pressure, and contact your dentist.

Broken, chipped or cracked teeth

Rinse your mouth with warm water and save any pieces of tooth in milk or water if you can find them. Apply a cold pack to the outside of the cheek to reduce swelling. A small chip without pain can usually wait for a regular appointment in the next few days, but call the dentist anyway so they can advise. A large break, a broken tooth that hurts, pink or red showing in the centre of the tooth, or a tooth that feels loose or pushed out of position needs prompt care, often the same day.

Cracks are trickier. A tooth that hurts sharply when you bite down and release, especially on something hard, may be cracked. Chew on the other side and see your dentist soon; cracks can spread.

Severe toothache and swelling

Rinse with warm water and gently floss around the tooth to remove any trapped food, which is sometimes the whole problem. A cold compress on the cheek may help. Over-the-counter pain relievers can be used as directed on the label if they are safe for you. Do not put aspirin or other tablets directly on the gum, as this can burn the tissue.

Throbbing pain, pain that keeps you awake, a bad taste, or a pimple-like bump on the gum can point to an infection that needs dental treatment. Call your dentist the same day. If swelling spreads or you have a fever, trouble swallowing or trouble breathing, go to an emergency room.

Lost filling or crown

Keep the crown if it comes off. Clean it gently and call your dentist. Pharmacies sell temporary dental cement that can hold a crown in place or cover a hole for a short time; follow the package instructions and never use household glue. Chew on the other side and avoid sticky or very hot or cold foods. These situations are usually not emergencies, but a tooth left open can break or become sensitive, so book soon.

Soft-tissue injuries

Cuts to the lips, tongue or cheeks tend to bleed a lot because the mouth has a rich blood supply. Rinse gently, then press a clean gauze or cloth firmly on the area for 15 minutes. A cold compress can help swelling. Deep cuts, cuts through the lip border, or bleeding that will not stop need medical attention.

Braces troubles

A poking wire can be pushed gently away from the cheek with a pencil eraser or covered with orthodontic wax. A loose bracket can usually wait until the orthodontist can see you; call for advice. Do not cut wires yourself unless your orthodontist has told you how.

Be ready before it happens

Save your dentist's number, and their after-hours instructions, in your phone. Ask at your next checkup what the practice does for emergencies outside office hours. Keep a small kit with gauze, a cold pack, a small lidded container, temporary dental cement and pain relievers suitable for your household. For sports, wear a properly fitted mouthguard. A few minutes of preparation can make a stressful moment a lot calmer.
