What is a common purpose of dental sealants?

Dental sealants are common preventive measures used in dentistry, particularly for children and adolescents, aimed specifically at reducing the risk of cavities. The primary function of dental sealants is to cover the occlusal surface of molars and premolars, which are often difficult to clean effectively due to their grooves and pits. By sealing these areas, sealants act as a physical barrier, preventing food particles and plaque from accumulating and thereby reducing the likelihood of decay.

Preventing cavities is particularly important because dental caries can lead to more serious dental issues if not addressed early. Sealants, therefore, play a significant role in dental public health strategies aimed at reducing the prevalence of cavities in susceptible populations, making them an essential tool in preventive dentistry.

In contrast, other purposes listed such as alleviating tooth sensitivity, whitening teeth, or restoring damaged teeth do not align with the primary function of dental sealants.
