Dental sealants play a vital role in preventing tooth decay and maintaining oral health. These thin, protective coatings are applied to the chewing surfaces of molars and premolars, where deep grooves and pits can trap food particles and bacteria, leading to cavities. By sealing these vulnerable areas, dental sealants create a barrier that effectively shields the teeth from decay-causing factors, particularly in children and teenagers who are more susceptible to cavities. This simple and painless preventive measure can significantly reduce the risk of dental problems, ensuring long-lasting dental health and saving both time and money on potential restorative treatments in the future.
