Types of cavities
Cavities come in a range of sizes and types, which include:
Smooth surface cavity
These cavities grow slowly and act to dissolve the tooth enamel. This type of cavity often develops between the teeth and, in some cases, can be reversed with proper dental care, such as regular professional cleanings and careful flossing and brushing.
Pits and fissures
These cavities appear on the chewing surface of the tooth or the front surface of the back teeth. These cavities tend to progress quickly, and early intervention is critical.
Receding gums can allow the root of the tooth to be exposed, which is not protected by the strong surface of the upper part of the teeth. When this develops, it may be necessary to treat the gum disease to halt the gum recession and avoid further decay. The tooth may become infected and require a root canal or more extensive treatment.
