Dental sealants are primarily indicated for the protection of the occlusal surfaces of teeth from caries. Sealants are a preventative measure applied to the chewing surfaces of the back teeth (molars and premolars), which have pits and fissures that can trap food particles and harbor bacteria, leading to decay. By sealing these vulnerable areas, sealants create a physical barrier that helps prevent bacteria and food debris from accumulating, significantly reducing the risk of cavities.

The effectiveness of sealants is particularly important in children and adolescents, whose newly erupted permanent molars are at high risk for caries. The application of sealants is a straightforward process that can provide long-lasting protection, often for several years, and is a widely recognized strategy in preventive dentistry.

While improving tooth color, enhancing tooth sensitivity, and decreasing gum bleeding are all dental-related features or issues, they do not align with the primary function of dental sealants. Thus, the correct indication focuses solely on their role in caries prevention, highlighting their importance in maintaining oral health.
