Dental Sealants: A Protective Barrier
Dental sealants are thin, protective coatings applied to the chewing surfaces of molars and premolars. These surfaces, often rough and pitted, are prone to accumulating food particles and bacteria. The sealant acts as a barrier, preventing these particles from lodging in the grooves and fissures, thus inhibiting bacterial growth and reducing the risk of cavities. The procedure typically involves applying a tooth-colored resin material to the surface of the tooth.
This material hardens, creating a smooth, protective layer that makes it difficult for food and bacteria to adhere.
Silver Diamine Fluoride (SDF): A Powerful Cavity Fighter
Silver diamine fluoride (SDF) is a topical liquid containing fluoride ions and silver ions. SDF works by penetrating the tooth’s surface and releasing fluoride, which strengthens tooth enamel and makes it more resistant to decay. Additionally, the silver ions in SDF inhibit bacterial growth within the tooth’s structure, further reducing the risk of cavities. SDF can be applied directly to areas affected by or at risk of cavities, including pits and fissures, and even early carious lesions.
It is often used as a minimally invasive treatment option.
