Dental cavities can be prevented with a combination of good oral hygiene and regular visits to the dentist. When too much oral bacteria takes up residence in your mouth, the acids they secrete can eat through the enamel, leading to holes known as cavities or dental caries.
The sooner you have a cavity filled, the better, since untreated cavities can grow larger and eventually cause serious toothaches and infection
When cavities are detected early, Dentist can generally treat them by removing the decaying tooth material and filling the hole with a sealant or composite filling.
