Besides brushing and flossing, there is another way to protect one's teeth from cavities.
Research published in the August issue of The Journal of the American Dental Association shows dental sealants can greatly reduce the risk of tooth decay in the back teeth known as molars in children and adolescents who have had sealant applied to those teeth.
The research determined that youth treated with dental sealants, which are thin, protective coatings that adhere to the chewing surface of molars, have about a 70 to 80 percent reduction in the occurrence of cavities, compared with those who do not receive sealants. Furthermore, there no reports of any adverse outcomes or health concerns related to use of sealants.
Both children and adults can benefit from sealants, but the earlier they are applied, the better, according to the ADA website, MouthHealthy.org. Sealing molars as soon as they come in can keep them cavity-free from the start.
How do sealants work? They act like "raincoats for your teeth," according to MouthHealthy.org. "When the cavity-causing bacteria that live in everyone's mouth meet leftover food particles, they produce acids that can create holes in teeth. These holes are cavities. After sealant has been applied, it keeps those bits of food out and stops bacteria and acid from settling on your teeth – just like a raincoat keeps you clean and dry during a storm."
Sealants, which can often last for several years before they need reapplied, can be used over areas of early decay to stop the cavity from getting worse. Some dental insurance plans cover them.
