How are cavities formed?

A cavity forms when dental plaque accumulates on the surface of a tooth. Plaque contains bacteria that transforms sugary food particles into acid. The acid then attacks the enamel and the inside of the tooth.

Treating a cavity

Rigorous oral hygiene is key to stopping the progression of a new cavity. Once the enamel has been compromised, however, the cavity has to be filled to prevent further damage to the tooth

What are fillings

A filling is a minor restoration that consists of removing the damaged portion of the tooth and filling it with composite resin or amalgam. The type of filling used depends on the condition and location of the tooth.
