Pits and Fissures are the most common dental problem found in children. Chewing teeth have grooves on the surface like mountain and valleys. These grooves are the hiding and dwelling places for oral bacteria’s causing decay since bristles of a brush do not reach to clean that area. Hence these areas start developing pits and fissures gradually leading to caries. To prevent this our clinic in Mumbai applies “dental sealants” on the surface of the tooth which covers the grooves and protects it from acid attacks and plaque.
