The most common situation when you need a dental filling is tooth decay (caries).
The dentist can discover tooth decay using several methods:
Inspection – some discolored spots may appear on your tooth. Some of them indicate decay.
Palpation – the dentist uses a dental explorer, a metal instrument with a sharp tip, to detect possible caries. Healthy enamel is hard, decayed enamel is softer.
Cavity detecting dye – it is a solution which , rinsed over the tooth will color the decayed area and will not adhere to the healthy tooth.
X-rays are useful in detecting caries on the sides of the teeth. They are not as accurate in detecting caries on the top (occlusal) surfaces of the tooth.
There are also less frequent reasons you may need a dental filling :
Cracked or broken teeth
Teeth that are worn from :
- tooth grinding (bruxism)
- nail biting
- overzealous use of toothbrushes or toothpicks
