PREVENTION OF DENTAL CARIES

Tooth decay is the most widespread infectious diseases in the world. It is caused by bacteria in the oral cavity, which are able to convert sugar from food into acids and interfere with the tooth enamel. Tooth decay is the result of long-term effects of plaque acids and hence poor oral hygiene.

Children are most affected by caries of the first permanent molars (sixes), which are pruned during the sixth year of life. They have a deeper and more complex system of holes and grooves on the biting pad than "milk" molars and poor hygiene are subject to rapid tooth decay.

Tooth decay is not inherited!

Inherited is only the quality of dental tissue and the size and shape of teeth!

Preventing tooth decay is in compliance with good oral hygiene, fluoridation of teeth to strengthen resistance of enamel to acids and molars with deep grooves the sealing is done (see below).

1. The first stage of dental caries is in enamel decalcification, looking like a chalk-white spot, which gradually change color over light brown to dark brown enamel and penetrates into deeper layers.








2. Caries invading dentine. Dentine tissue is not as hard as enamel and the caries process is spreading faster here.










3. Tooth decay penetrated the dentine to the tooth pulp, which is stored nerve and blood supply. This decay can be very painful and also may get a bacterial infection through the root of the tooth in greater depth and cause the abscess (inflammatory deposit in the root tip).

SEALING TEETH

For deep fissural complexes permanent molars and premolars sealing is recommended as a preventative non-invasive method. The holes are "filled" with white fillings without disturbing the glass drilling. This will be treated teeth easier to clean and then we can also eliminate the risk of dental caries.

Sealing is carried out preferably after pruning the first and second permanent molars, it is about 6 and 12 year of life. Fissure tooth may already be infected tooth decay.
