Chipped Broken Or Cracked Tooth

Overview

A chipped, broken, or cracked tooth means part of the hard outer layer of a tooth has been damaged. The damage can be tiny, like a small rough edge, or serious, like a deep crack that reaches the soft inner part of the tooth where the nerve and blood supply sit. Even a small chip should be checked by a dentist, because some cracks are hard to see and can get worse over time.

Very common. Many people chip a tooth at some point, and cracks are especially common in teeth that already have large fillings or have been repaired before.

Anyone can chip or crack a tooth. Children often do it through falls or play. Adults often do it by biting hard foods or grinding their teeth. Older adults may get cracks around old fillings or worn teeth.

Symptoms

Common symptoms

• A rough or sharp edge that you can feel with your tongue
• Pain when chewing or biting down
• Sensitivity to hot, cold, or sweet foods and drinks
• A visible line, chip, or missing piece of tooth
• Pain that comes and goes, especially when you release a bite
• Food getting caught in the broken area

Symptoms in children

• Crying or refusing to eat after a fall or knock to the mouth
• A rough or missing piece of tooth
• Bleeding from the gum near the tooth
• Fear of brushing or touching the tooth
• A baby tooth that looks pushed out of place after injury

Symptoms in older adults

• A crack around an old filling or crown
• Sensitivity that comes and goes
• A tooth that looks whole but hurts when chewing
• Wear and tear from many years of use
• Dry mouth or acid reflux making teeth more fragile

Causes

Main causes

• Biting down on something hard, such as ice, bones, hard sweets, or unpopped popcorn kernels
• A fall, sports injury, or blow to the face
• Grinding or clenching teeth, especially during sleep
• Large fillings or root canal treatment that can weaken the tooth over time
• Acid erosion from foods, drinks, or stomach acid that thins the enamel
• Temperature changes from very hot and cold foods, which can stress teeth with old fillings

Risk factors

• Playing contact sports without a mouthguard
• Frequent grinding or clenching of teeth
• A history of large fillings or repeated dental work
• Dry mouth from medicines or health conditions
• Acid reflux or frequent vomiting
• Eating lots of hard foods or chewing ice
• Older age and years of wear on the teeth

When to see a doctor

See a doctor urgently if:

• You have severe tooth pain or pain that keeps you awake.
• You have facial swelling, fever, or pus near the tooth.
• A permanent tooth has been knocked out or is very loose after injury.
• Bleeding from the mouth does not stop with firm pressure.
• A broken tooth has a sharp edge that cuts your tongue or cheek.
• You have a deep crack and can see pink or red tissue inside.

Book a routine appointment if:

• You notice a small chip or rough edge, even if it does not hurt.
• You feel sharp pain when chewing or when you release a bite.
• A tooth is sensitive to hot or cold drinks for more than a few days.
• You can see a line or crack in a tooth.
• You have a filling or crown that feels rough or loose.

Diagnosis

A dentist will ask what happened and look closely at your mouth. They may gently tap or press the tooth, check your bite, and use a light or cold test to see how the tooth responds. X-rays are often used to look at the root and the bone around the tooth.

Tests that may be done

• Dental examination with a small mirror and probe
• Dental X-ray to check the root and bone
• Bite test to find the painful spot
• Cold or sensitivity test to check the nerve
• Shining a bright light through the tooth to look for cracks
• Sometimes a 3D scan for a more detailed view

What to expect at your appointment

The visit is usually quick and gentle. Your dentist will explain what they find and whether the tooth needs treatment now or can be watched. Some repairs can be done the same day, while others may need a follow-up appointment.

Treatment

Treatment depends on how deep the damage is and where it is. A small chip may only need smoothing. A larger break may need a tooth-coloured filling, bonding, or a crown. If the inner nerve is exposed or infected, root canal treatment may save the tooth. Ask a dentist or qualified healthcare provider which option is right for you.

Self-care at home

• Rinse your mouth gently with warm water to clean the area.
• If there is bleeding, bite gently on clean gauze or a clean cloth for about 10 minutes.
• Hold a cold pack against your cheek for swelling, wrapped in a cloth.
• Avoid chewing on the damaged tooth until a dentist has checked it.
• Keep the tooth clean with a soft toothbrush and gentle brushing.
• If you have dental wax, you can cover a sharp edge to protect your tongue and cheek.
• Ask your pharmacist or dentist about safe pain relief options if needed.

Medical treatments

Your dentist may smooth a rough edge, repair the tooth with a tooth-coloured filling or bonding material, or fit a crown to protect it. If the crack reaches the nerve, they may recommend root canal treatment to clean and seal the inside of the tooth. A loose tooth may be splinted to nearby teeth while it heals. If there is infection, your dentist or doctor will decide whether more treatment is needed.

When is surgery considered?

Surgery is not usually needed for a simple chip or crack. If a tooth is badly broken below the gum line, very loose after a jaw injury, or cannot be saved, your dentist may refer you for extraction or specialist care. A suspected broken jaw needs hospital care.

Living with this condition

You can usually eat and drink with care while you wait for treatment. Avoid biting hard foods on the damaged side. Keep brushing and flossing gently, and use a soft toothbrush. If the tooth feels sharp, dental wax can help protect your mouth.

Lifestyle tips

• Wear a mouthguard for contact sports.
• Avoid chewing ice, hard sweets, bones, and unpopped popcorn.
• If you grind your teeth, ask your dentist about a night guard.
• Keep regular dental check-ups.
• Limit sugary drinks and acidic foods that can weaken enamel.

Diet and exercise

Choose softer, cooler foods if the tooth is sore, such as yoghurt, mashed vegetables, soup, or scrambled eggs. Avoid very hot, very cold, or very hard foods until you have been checked. You can keep exercising, but avoid contact sports until your dentist says it is safe, and wear a mouthguard when you return.

Mental health and emotional wellbeing

Dental pain or dental fear can cause worry, poor sleep, and stress. This is common and understandable. If pain or anxiety is affecting your mood, tell your dentist — they can explain each step and help you feel more in control. If you feel hopeless or have thoughts of harming yourself, contact your local crisis support service or your local emergency number right away.

Prevention

Not every chip or crack can be prevented, but you can lower the risk. Wear a mouthguard for sports, avoid chewing ice and hard objects, and treat teeth grinding. Regular dental check-ups can find small problems before they get worse.

Vaccines

There is no vaccine for chipped, broken, or cracked teeth.

Screening programmes

Regular dental check-ups can spot cracks, worn fillings, and early damage. Ask your dentist how often you need a check-up based on your own risk.

Complications

If left untreated

• The crack can spread deeper into the tooth.
• The nerve can become inflamed or infected.
• An abscess can form, causing pain, swelling, and fever.
• The tooth may become loose or need to be removed.
• Infection can spread to nearby areas of the face or jaw, which is rare but serious.

Long-term outlook

Most chipped or cracked teeth can be repaired, especially when they are checked early. Some teeth need more than one visit, and a few cannot be saved, but there are good ways to restore comfort, eating, and your smile. Seeing a dentist promptly gives you the best chance of a good result.
