Sealants, or pit and fissure fillings, are an important preventive measure against tooth decay. Essentially, they act as a barrier on the teeth that prevents the entry of cariogenic bacteria.

Sealants are a thin, flowable material applied preferably right after the eruption of the first and second permanent molars. Their purpose is to seal all the grooves and fissures that these teeth naturally have, so that food debris and bacteria, which can sometimes be difficult to clean even with brushing, do not get trapped during chewing.

Pit and fissure fillings can also be applied to other teeth beyond molars that have deep grooves and fissures, meaning teeth at higher risk of decay. Naturally, they cannot be used on teeth with large carious lesions. The application of sealants is recommended for all children from the age of 5, as well as later in life, and for adults with increased risk of cavities, as an excellent preventive measure.

The procedure for placing sealants is very easy, simple, and quick, and is usually completed in a single visit. It is completely painless since no tooth drilling or anesthesia is needed. The dentist will prepare and properly clean the surfaces of the tooth that will receive the sealant. Using special brushes and materials applied locally, the dentist will place the thin flowable resin.

Sealants are highly effective against tooth decay and can remain in place for several years. During every dental check-up, the dentist will examine the sealants for any wear or damage.
