Signs and symptoms of needing a filling
There are many instances in which a filling is required. Normally dental fillings are needed when there is a cavity caused by one of the following:
- tooth decay (caries) due to sugary diet and bacteria forming acids that dissolve the enamel and dentine. If left untreated, cavities can lead to serious dental problems – including pain, infection and abscess.
- enamel loss due to wear and abrasion causing sensitivity
- fractures caused by trauma
- crack lines due to weak tooth structure and heavy bite or grinding
- a broken or lost filling.

- sensitivity to heat or cold or pressure
- pain on biting or chewing
- floss that keeps tearing in a particular gap
- Discolouration or shadowing of tooth surfaces.
- rough tooth surface.

Fillings serve to stop further tooth decay and restore the function, integrity and morphology of the missing tooth structure.
Five different types of filling materials are used:
- composite resins that are tooth coloured fillings
- ionomers – also tooth coloured fillings that release small amounts of fluoride
- ceramic/porcelain fillings – which are custom produced for larger fillings that need external surfaces of the tooth covered.
The right filling choice for you will depend on your dentist’s recommendation and your personal preference and budget.
In general, placing a filling involves four stages:
- Anaesthetic (optional). The area is made numb to minimise discomfort during the procedure.
- Preparation of tooth. The tooth
