Many researches on dental caries has showed us that fissures on the chewing surfaces of molars are prone to decay. Even if teeth are brushed regularly, tooth brushes can not reach these fissures and food and dental plaque collected on these areas cause caries.

Fissure sealants are liquid fillings containing fluoride. They provide easily cleanable surfaces by filling in the fissures on the chewing surfaces of the teeth. Fluoride in the sealants are released regularly and prevents the cavities on these surfaces. 

Fissure sealants are applied in only a fee second without a need for anaesthesia. 

When are sealants applied to children?

Between ages 5-7 when the first permanent tooth start to erupt, and between ages 11-12 when the second molar teeth erupt fissur sealants are applied, as the first molars erupt. Dental caries mostly occur in the first year of the teeth. Teeth are not completely mineralised and prone to cavities as they are softer in the first year. However, sealant can be applied on teeth any time unless there is a cavity.
