Why is sealing necessary?

It is scientifically proven that the sealings, carried out correctly, reduce the risk of cavities.
Sealing is a non-invasive intervention that is carried out on the chewing surface of the first permanent molars: the furrows are cleaned and then sealed with a resin containing fluoride, so that the food can no longer stop inside and the enamel is strengthened.
It is usually done between the ages of 6 and 8 when these teeth erupt, but in some cases they can also be done on other permanent teeth or milk teeth.
