What Are Dental Sealants?
Dental sealants are thin, protective coatings applied to the chewing surfaces of back teeth. These molars and premolars are prone to cavities due to their grooves, which can trap food particles and bacteria. Sealants create a smooth, protective layer that prevents plaque from accumulating, making it easier to keep these teeth clean and reducing the risk of decay.
How Fluoride Strengthens Teeth
Fluoride is a naturally occurring mineral that strengthens enamel, the outer layer of the teeth. By making enamel more resistant to acid attacks from bacteria, fluoride can help reverse early signs of decay. It is commonly found in toothpaste, mouth rinses, and many public water supplies, providing consistent, low-level protection against cavities.
The Combined Power of Sealants and Fluoride
When used together, sealants and fluoride provide a two-layer defense against cavities. Fluoride strengthens the enamel across all tooth surfaces, while sealants offer targeted protection on the back teeth’s vulnerable chewing surfaces. This combination is especially effective for children, who may have difficulty thoroughly brushing their molars.
Benefits for Adults and Children
While sealants are typically applied to children’s teeth as soon as their molars come in, adults can also benefit, especially those with a history of cavities or deep grooves in their molars. Fluoride remains beneficial at any age, continuously reinforcing enamel and helping protect against decay as adults face new dental challenges over time.
How to Get Sealants and Fluoride Treatments
Applying dental sealants is a quick, painless process that can be done during a routine dental visit. Dentists can also provide fluoride treatments for extra protection, particularly for patients at high risk of decay. Regular check-ups allow your dentist to assess the effectiveness of these treatments and recommend additional preventive measures if needed.
