A dental filling is used to repair a tooth. There are many reasons why a patient may need a filling, for example:
- Damage from decay (dental caries)
- A fracture from trauma
- Tooth hypersensitivity from abrasion or erosion
- A developmental defect requiring repair
- To replace an old or leaking filling
- To alter a tooth’s colour or shape to improve aesthetics
There are three types of fillings: composite, glass ionomer resin cement (GIC) and amalgam.
