A tooth can be damaged by cavities and fracture caused by dental trauma. On delaying the treatment, decay will reach the nerve which will lead to infection. The infected nerve will need either root canal treatment or tooth removal. Tooth unfriendly sugar and bacteria attack the tooth structure which if left untreated can cause the cavity. Acidic drinks can also cause cavities in the teeth by eroding the tooth structure. In the very early stages, the decaying process can be halted with proper oral hygiene measures, dietary advice, and regular dental visits. However, if the decay has caused the loss of tooth structure, then the white filling is required to restore the structure. There are different types of dental filling materials available. Depending on the assessment and clinical situation, the dentist will suggest you the best material of choice.
