A broken or cracked tooth ranges from a small chip in the enamel to a split running down through the root. How deep the break goes, and whether it reaches the nerve or extends below the gum, decides whether the tooth can be saved.
Teeth do not heal as bones do. A crack tends to spread with chewing, so early treatment gives the simplest repair. Many fractured teeth can be restored with bonding, a crown or root canal treatment, while a vertical root fracture usually means extraction.
Symptoms
- A sharp edge felt by the tongue or a visibly missing piece
- Sharp pain on biting that goes when you release
- Sensitivity to cold, heat or sweet foods
- Pain that comes and goes and is hard to pinpoint
- A pink or red spot in the break, showing the nerve is exposed
- Swelling or a gum boil beside the tooth
- A tooth that is loose or has moved after a blow
Causes and risk factors
Front teeth are usually broken by falls, sports and accidents. Back teeth more often crack from biting something hard such as ice, olive stones or bone, from night-time grinding and clenching, or because a large old filling has left thin unsupported walls. Root-filled teeth without a crown are more brittle. Decay beneath a filling and sudden temperature changes add to the risk, and cracks become more common after 40.
How it is diagnosed
- Clinical examination with magnification: The dentist inspects with loupes or a microscope, probes the gum and may stain the tooth to show a crack.
- Bite test: Biting on a small plastic device, cusp by cusp, reproduces the pain of a cracked tooth.
- Transillumination: A bright light passed through the tooth stops at a crack line.
- Dental X-rays: Show root fractures, nerve involvement and bone, though fine cracks are often invisible.
- Cone beam CT: A 3D scan for suspected root fractures and injuries after trauma.
- Pulp vitality testing: Cold or electric testing shows whether the nerve is healthy.
Treatment options
- Smoothing or composite bonding: For small enamel chips, usually in one visit.
- Reattaching the fragment: If you keep the piece moist in milk or saliva, it can sometimes be bonded back.
- Onlay or crown: Holds a cracked back tooth together and protects the cusps.
- Root canal treatment then crown: When the fracture or crack reaches the nerve.
- Splinting: Stabilises a tooth loosened or a root fractured by trauma for a few weeks.
- Extraction and replacement: For split teeth and vertical root fractures, followed by an implant or bridge.
- Night guard: Protects against further cracks if you grind.
When it is urgent
A tooth knocked out completely should be put back in its socket or kept in milk and brought to a dentist within an hour. Go to an emergency department locally for facial swelling that is spreading, difficulty swallowing or breathing, uncontrolled bleeding, or a blow to the face with suspected jaw fracture or loss of consciousness.
Travelling to Türkiye for treatment
A fresh injury needs a local dentist the same day. Definitive work is a different matter: crowns typically need 5 to 7 days with two or three appointments, and an extraction with implant involves two trips some 3 to 6 months apart. Ask for a temporary repair at home first if you are in pain, and bring any X-rays.
Send your reports, scans and a short history and a Clinic-Y coordinator replies within 24 hours with suitable teams and written, all-inclusive proposals side by side. Reviewing your case is free.
Frequently Asked Questions
Can a cracked tooth heal by itself?
No. Enamel and dentine cannot knit together. The aim is to stop the crack from spreading.
It only hurts sometimes. Can I leave it?
That on-off biting pain is typical of a crack. Waiting risks the tooth splitting beyond repair.
Will I definitely need a root canal?
Only if the nerve is exposed, inflamed or has died. Many cracked teeth need only a crown.
A piece of filling broke off, not tooth. Is that urgent?
It is not an emergency, but have it repaired within a couple of weeks before decay or a fracture follows.
