Sealants are a safe and painless way of protecting teeth from tooth decay. They are a kind of “varnish” applied to the surface of the teeth, forming a hard shield that prevents food and bacteria from entering the small spaces and fissures of healthy teeth and causing deterioration.
They are an effective preventive measure, but they do not replace good oral hygiene habits or regular visits (every 6 months) to the dentist.

Fissure sealants are indicated for the first and second permanent molars, as well as the premolars, whose eruption periods are between 5 and 8 years and between 10 and 14 years, respectively. Reapplication is indicated if there is partial or total loss of the sealant, thereby maximising its effectiveness. Sealants can wear down over time, which may mean they need replacing, so check-up and maintenance appointments will always be necessary to ensure their integrity.
