Dental Sealants in Winchester

Dental sealants are a preventive dental treatment involving the application of a plastic material to the chewing surfaces of the back teeth, specifically the premolars and molars. These chewing surfaces often contain depressions and grooves, known as pits and fissures. Dental sealants are designed to bond with these surfaces, creating a protective barrier that helps safeguard the enamel from plaque and acidic substances.

While thorough brushing and flossing are effective at removing food particles and plaque from the smooth surfaces of teeth, they may not reach all the way into the pits and fissures. Sealants serve as a crucial defense by "sealing out" plaque and food from these vulnerable areas, reducing the risk of decay.

The application of dental sealants is a straightforward process, typically performed by our dentists in just a few minutes per tooth. Here's how it works:

The teeth to be sealed are first cleaned thoroughly.
The chewing surfaces are then roughened using an acid solution, enhancing the adherence of the sealant to the tooth.
The sealant material is carefully applied to the tooth enamel, where it bonds directly with the tooth's surface and is allowed to harden.
Sometimes, a special curing light is used to expedite the hardening process.

Once applied, dental sealants can effectively protect the tooth surface from decay as long as they remain intact. They can withstand the pressures of normal chewing and typically last for several years before requiring reapplication. During your regular dental check-ups, our dentists will assess the condition of the sealants and reapply them as needed.

The susceptibility to pit and fissure decay starts early in life, making children and teenagers ideal candidates for sealants. However, adults can also benefit from this preventive treatment.
