What is the primary purpose of dental sealants?

• A. To enhance the appearance of teeth
• B. To prevent cavities in molars by sealing the tooth surface
• C. To relieve tooth sensitivity
• D. To protect against gum disease

Answer: (B)

The primary purpose of dental sealants is to prevent cavities in molars by sealing the tooth surface. Sealants are thin plastic coatings applied to the chewing surfaces of back teeth, typically the molars, where decay is most likely to occur. These areas have grooves and pits that can trap food particles and plaque, making them vulnerable to cavities. By sealing these surfaces, dental professionals can provide a protective barrier that helps keep out decay-causing bacteria and plaque, significantly reducing the risk of cavities. This preventive measure is particularly effective in children and adolescents, who are more prone to tooth decay in these areas.
