What’s a cavity or tooth decay?

Tooth decay is a bacterial disease that attacks and destroys the hard surfaces of teeth. It is a condition that occurs as much in adults as in children. It is not uncommon to see cavities on teeth that have just erupted in the mouth! The first permanent molars are the first adult teeth that appear in the mouth, around the age of 6 years. They are often decayed because at this age a child does not have enough manual dexterity to properly brush his teeth. Indeed, research shows that it is these first molars that end up having root canal treatments in adulthood.


The oral cavity is one of the areas of the body that holds the most bacteria! Between 6 to 20 trillion to be more accurate, grouped in more than 200 different species! It will make you think twice before kissing someone or sharing an ice cream😊.









Some of these bacteria maintain good oral health, others cause dental disease. To have a decay, you need the presence of three elements in the mouth: a tooth, bacteria and sugar.


Cariogenic bacteria feed on sugar present in food and convert it into acid, which subsequently damages the enamel of the tooth. If not treated, a cavity can progress to the inner layer of the tooth, the dentin and can finally reach the dental pulp or nerve. In the latter case, a root canal should be considered since an infected pulp is a serious condition that can put someone's life at risk.

It is therefore important to have adequate oral hygiene to eliminate bacteria as much as possible and to choose foods low in sugar and acidity to prevent the deterioration of the enamel. Above all, do not forget to do your dental cleaning every 6 months!
