What it is
A tooth-coloured filling uses a composite resin bonded to the tooth to replace lost structure after decay, fracture or wear. The material is shaped and hardened directly in the mouth and polished to match the tooth.
Who it may suit
- Decay detected at a check-up or on an X-ray
- A chipped edge on a front or back tooth
- Worn areas near the gum line
- Replacement of an old, failing filling
Signs you may need it
- Sensitivity to sweet, hot or cold
- A rough edge you can feel with your tongue
- Food packing between two teeth
- A visible dark spot or hole
How the treatment works
- 1
Diagnosis
Clinical examination and, where needed, an X-ray to see the extent of decay.
- 2
Preparation
Local anaesthetic if required, then removal of decay and preparation of the cavity.
- 3
Placement
Composite is bonded in layers, shaped to the tooth and hardened with a curing light.
- 4
Finishing
The bite is checked and the filling is polished.
Visits and recovery
Most fillings are completed in one visit. Mild sensitivity for a few days afterwards is common, particularly with deeper cavities.
Benefits
- Matches the shade of the natural tooth
- Bonds to tooth structure, so less healthy tooth needs removing than with some older techniques
- Completed in a single appointment in most cases
Limitations
- Very large cavities may be better restored with a crown or an indirect restoration
- Composite can stain at the margins over years
- Fillings do not last indefinitely and need monitoring
Risks to be aware of
Every dental procedure carries some risk. Your dentist will discuss these with you in person, based on your own examination and X-rays.
- Post-operative sensitivity
- Nerve inflammation where decay was deep, occasionally requiring root canal treatment
- Chipping under heavy bite forces
Aftercare
- Wait until numbness wears off before eating
- Report a high bite so it can be adjusted
- Clean between the teeth daily to protect the margins
- Reduce frequency of sugary snacks and drinks
When to contact the clinic
- The bite feels high after the anaesthetic wears off
- Sensitivity that increases over the following weeks
