Dental caries

Causes, prevention and treatment of dental caries.

Did you know that tooth decay is one of the most widespread diseases in the world?

Causes of dental caries

Cavities are caused by the bacteria present in dental plaque. They feed of sugar and transform it into a type of acid. This acid gradually decalcifies the teeth, possibly leading to tooth loss.


Thankfully, cavities can be easily avoided. An annual check-up with your dentist allows any tooth decay to be rapidly detected. If needed, your dentist could also suggest a preventive treatment.

Pit and Fissure Sealant

Molars and premolars have grooves on their occlusal surfaces. Food particles and bacteria accumulate in them, putting the tooth at risk of developing a cavity. Dental sealant cover these pits and fissures. The treatment is generally done as soon as the adult teeth appear, around the age of 6.

Fluoride Application

Fluoride helps make teeth more resistant to tooth decay, and can even remove emerging caries. Fluoride application is usually reserved to children and to adults who are prone to tooth decay.


To treat a cavity, the dentist remove the decayed part of the tooth. There are many options to obturate the cavity:

  • Composite resin restauration
  • Amalgam restauration
  • Ceramic inlays/onlays
