Broken tooth: what to do and when to see a dentist
A broken tooth should be checked by a dentist as soon as possible, especially if it causes pain, bleeding, swelling, sensitivity, a sharp edge or difficulty chewing. Even small chips can expose the tooth to further damage if they are left untreated.
A tooth can chip, crack or break for several reasons. Some breaks happen suddenly after an accident or sporting injury. Others happen while biting on hard food. In many cases, a tooth breaks because it was already weakened by decay, a large old filling, grinding, trauma or previous dental treatment.
Dentists In Annerley provides emergency dental care in Brisbane Southside from our clinic at 470 Ipswich Road, Annerley. We commonly help patients from Annerley, Greenslopes, Yeronga, Fairfield, Moorooka, Tarragindi, Woolloongabba and nearby suburbs.
What to do immediately after breaking a tooth
The first few minutes matter. The goal is to protect the tooth, reduce further irritation and organise a dental assessment.
- Rinse your mouth gently with warm water.
- Save any broken tooth pieces if you can find them.
- Place fragments in a clean container and bring them to your appointment.
- Avoid chewing on the affected side.
- Use dental wax to cover a sharp edge if it is cutting your tongue or cheek.
- Use sugar-free chewing gum only as a short temporary cover if dental wax is not available.
- Call a dentist as soon as possible for advice and an appointment.
Do not try to glue the tooth back together at home. Household glues and non-dental products can damage the tooth and soft tissues. If the injury happened during sport, trauma or an accident, mention this when you call so the team can triage the situation properly.
When is a broken tooth a dental emergency?
Some small chips are not painful and may be repaired routinely. However, a broken tooth becomes more urgent when the deeper tooth structure, nerve or surrounding gum is affected.
You should contact an emergency dentist quickly if you notice:
- Severe pain after the tooth breaks
- Bleeding from the tooth or surrounding gum
- Swelling around the tooth, jaw or face
- Difficulty biting, chewing or closing your teeth together
- A sharp edge cutting your tongue, lip or cheek
- Sensitivity to cold, heat or air
- A loose tooth after trauma
- A broken crown, filling or bridge
- A bad taste, pus or signs of infection
If swelling is spreading, you feel unwell, you have fever, or you are having trouble breathing or swallowing, seek urgent medical care. Dental infections and facial swelling can become serious.
Why you should not ignore a broken tooth
A broken tooth may seem minor at first, especially if it does not hurt. The problem is that exposed tooth structure can become more sensitive, more fragile and harder to clean. A crack can also travel deeper over time.
Prompt dental care can help stabilise the tooth, reduce discomfort and lower the risk of further damage. If the break has exposed the nerve, delaying treatment may increase the chance of needing more complex care such as root canal treatment or tooth extraction.
Common types of broken teeth
The right treatment depends on where the tooth has broken, how much tooth structure is left and whether the nerve has been affected.
- Minor chip: A small piece of enamel breaks away. This may only need smoothing or bonding.
- Cracked tooth: A crack runs through part of the tooth. It may cause pain when biting or sensitivity.
- Broken cusp: A corner or biting surface breaks, often around a filling.
- Deep fracture: The break extends close to or into the nerve of the tooth.
- Split tooth: The tooth has cracked into separate segments and may not be restorable.
- Broken crown or filling: An existing restoration breaks or comes away, exposing tooth underneath.
How a dentist may treat a broken tooth
Treatment starts with an examination. Your dentist may check the tooth visually, test the bite, take dental x-rays and assess whether the nerve or root has been affected.
Treatment may involve:
- Smoothing a sharp edge if the chip is minor
- Repairing the tooth with a tooth-coloured dental filling
- Bonding the tooth where suitable
- Placing a dental crown if the tooth needs more protection
- Root canal treatment if the nerve is infected or exposed
- Extraction if the tooth cannot be predictably saved
- Replacement options such as a bridge, denture or implant if a tooth is removed
Dentists In Annerley offers CEREC same-day crown technology for suitable cases. This may allow some broken teeth to be restored with a crown in one visit, depending on the tooth, fracture and clinical situation.
Can a broken front tooth be repaired?
Often, yes. A broken front tooth may be repaired with smoothing, bonding, a filling, a veneer or a crown depending on how much tooth has broken and whether the nerve is involved.
If the break affects your smile, your dentist will also consider shape, colour and symmetry. For longer-term cosmetic planning, you may want to compare options on our veneers and cosmetic dentistry pages after the urgent problem is stable.
Can a badly broken back tooth be saved?
Sometimes. Back teeth take heavy biting forces, so the amount of remaining tooth structure matters. A back tooth with a broken cusp may be restorable with a filling or crown. A deep fracture below the gumline may have a poorer outlook.
If the tooth cannot be saved, your dentist can explain replacement options. These may include dentures, bridges or dental implants for suitable patients.
What if the broken tooth is painful?
Pain can mean the tooth nerve, gum or surrounding bone is irritated or infected. Pain when biting may also suggest a crack or fracture that flexes under pressure.
If pain is severe, throbbing or keeping you awake, read our guide on severe toothache emergencies and contact the clinic. Pain relief may help temporarily, but it does not fix the underlying cause.
What if your child breaks a tooth?
If a child breaks a tooth, call a dentist for advice. The best next step depends on whether it is a baby tooth or adult tooth, whether the tooth is loose, whether there is bleeding and whether the child has had a knock to the head or face.
For children, avoid placing aspirin on the gum or tooth. If there are signs of head injury, heavy bleeding, facial swelling or the child is very unwell, seek urgent medical care. You can also read more about our children’s dental care.
What if the tooth is knocked out completely?
A knocked-out adult tooth is a time-sensitive dental emergency. Do not scrub the root. Hold the tooth by the crown, keep it moist and seek emergency dental care immediately.
For step-by-step advice, read our guide: knocked-out tooth emergency.
What is the best next step?
If you have broken a tooth, book an emergency dental appointment or call the clinic. The dentist can assess the fracture, check whether the nerve is affected and explain the most appropriate repair options.
If you are unsure whether to book emergency care, use this simple rule: pain, swelling, bleeding, sharp edges, sensitivity or difficulty chewing means it should be checked promptly.
