Dental Injuries Tooth Loss

Overview

Dental injuries are damage to a tooth or the gums and mouth around it after a bump, fall, sports injury, or accident. Tooth loss means a tooth is completely knocked out or lost because of injury. It can involve a baby tooth, a permanent tooth, or several teeth. Quick first aid and dental care can make a big difference.

Yes. Dental injuries are common. They happen a lot in children, teens, and people who play contact sports.

Anyone can hurt a tooth. Risk is higher in children, teens, athletes, people who fall, and older adults with weak teeth, gum disease, or dentures.

Symptoms

Common symptoms

• Pain or tenderness in a tooth or the gums after a bump or fall
• Bleeding from the gum or inside the mouth
• A tooth that is chipped, cracked, broken, or has a sharp edge
• A tooth that is loose, moved out of place, or feels different when you bite
• A tooth that is missing after an injury
• Swelling of the lip, gum, or face
• Sensitivity to hot, cold, or sweet foods
• Trouble chewing or opening the mouth

Symptoms in children

• Crying or fussing more than usual after a fall or bump
• Refusing food or drink, or drooling more than usual
• Swelling, bruising, or a cut around the mouth

Causes

Main causes

• Falls, especially in young children and older adults
• Sports and play injuries, particularly without a mouthguard
• Road traffic crashes, cycling, or scooter accidents
• Fights or a direct blow to the face
• Biting hard food, ice, or hard objects
• Weakened teeth from decay or gum disease can break or fall out after a small injury

Risk factors

• Playing contact sports without a mouthguard
• Being a child or teenager
• Older age, gum disease, or weak teeth
• Previous dental work such as large fillings or crowns
• Not wearing a seatbelt or helmet
• Limited access to regular dental care

When to see a doctor

See a doctor urgently if:

• A permanent tooth is knocked out — get dental help immediately.
• A tooth is broken with severe pain or a visible pink or red center.
• A tooth is loose, moved, or pushed into the gum after an injury.
• A baby tooth is knocked out or pushed into the gum.
• A cut in the mouth that will not stop bleeding or may need stitches.
• Facial swelling, fever, or pus.

Book a routine appointment if:

• A chipped tooth with no pain
• A rough or sharp tooth edge
• Sensitivity that comes and goes
• A follow-up check after a dental injury
• You want to talk about replacing a missing tooth

Diagnosis

A dentist or doctor will ask how the injury happened and check your mouth, teeth, gums, and bite. They will look for loose teeth, broken pieces, cuts, and signs of infection or jaw injury.

Tests that may be done

• Dental examination — the dentist looks at the tooth, gums, bite, and nearby tissues.
• Dental X-rays — pictures that show the root and bone.
• Sensibility tests — gentle checks to see if the tooth still responds.
• CT scan — only for severe face or jaw injuries.

What to expect at your appointment

The dentist will explain whether the tooth can be saved and what to do next. You may need follow-up visits to check healing and watch for changes.

Treatment

Treatment depends on which tooth is hurt and how badly. The goals are to save the tooth if possible, relieve pain, prevent infection, and restore eating and appearance. Quick care gives the best chance of a good outcome.

Self-care at home

• For a knocked-out permanent tooth, act fast. Pick it up by the white crown, not the root. Rinse gently with milk or saline if it is dirty. If you can do it safely, put it back in the socket and bite gently on a clean cloth. If not, keep it in milk or saline and get dental help immediately.
• Do not put a baby tooth back in the gum. See a dentist the same day.
• For a broken tooth, save any pieces in milk or saline and take them to the dentist.
• Hold a cold pack to the outside of the face for swelling.
• Eat soft foods and avoid hard, sticky, or very hot foods for a few days.
• Keep the mouth clean. Brush gently and follow your dentist's advice about rinsing.
• Ask a pharmacist or dentist about safe pain relief.

Medical treatments

A dentist will choose treatment based on the tooth and the injury. Options include smoothing a sharp edge, repairing a chip with a filling or bonding, joining a loose tooth to its neighbours for support (splinting), root canal treatment (cleaning and sealing the inside of the tooth), reimplanting a knocked-out permanent tooth, or replacing a lost tooth with a bridge, denture, or implant. The team will also check for infection and damage to the gums, jaw, or other teeth. Complex injuries may need a specialist.

When is surgery considered?

Surgery may be needed for a badly broken tooth that cannot be repaired simply, a broken jaw, complex facial injuries, or to place a dental implant. Your dental team will explain the benefits and risks.

Living with this condition

After a dental injury, you may need to eat soft foods, avoid using the injured tooth, and keep the area clean. Follow your dentist's advice about follow-up visits. If you have lost a tooth, it can affect eating, speaking, and confidence, but help is available.

Lifestyle tips

• Wear a mouthguard for contact sports and training.
• Wear a seatbelt and a helmet for cycling or scooters.
• Avoid chewing ice, hard sweets, or opening packets with your teeth.
• Keep up regular dental checkups.
• Do not smoke; it can slow healing and harm gum health.

Diet and exercise

Eat soft, healthy foods while you heal, such as soup, mashed vegetables, yogurt, and soft fruit. Avoid hard, sticky, or very sugary foods that can hurt the area or raise decay risk. Ask your dentist when you can return to sport. You can often stay active, but avoid contact sports until you are cleared.

Mental health and emotional wellbeing

Losing a tooth or having a dental injury can affect how you feel about your smile, eating, and speaking. It is common to feel anxious, embarrassed, or low. Talk to your dentist, doctor, or someone you trust. If you feel overwhelmed or unsafe, contact your local crisis support service or your local emergency number.

Prevention

Many dental injuries can be prevented, but not all. Good habits and safety gear lower the risk.

Vaccines

Vaccines do not prevent dental injuries. Keep up with routine vaccines for general health.

Screening programmes

Regular dental checkups can find weak teeth, gum disease, or old fillings before they cause problems.

Complications

If left untreated

• Infection or an abscess (a pocket of pus) in the tooth or gum
• Spread of infection to the face or jaw
• Bone loss around the tooth
• Teeth that shift and bite problems
• Long-term tooth loss
• Trouble eating, speaking, or feeling confident
• Need for more complex treatment later

Long-term outlook

Most people do well after a dental injury, especially when they get care quickly. Even if a tooth is lost, modern dentistry can often restore how you look and chew. Follow-up visits help protect your other teeth and gums.
