Sealants are a thin coating painted on the chewing surfaces of teeth — usually the back teeth (the premolars and molars) that prevent tooth decay. The painted on liquid sealant quickly bonds into the depressions and grooves of the teeth, forming a protective shield over the enamel of each tooth.
Benefits of Sealants
Although thorough brushing and flossing can remove food particles and plaque from smooth surfaces of teeth, they cannot always get into all the nooks and crannies of the back teeth to remove the food and plaque. Sealants protect these vulnerable areas from tooth decay by “sealing out” plaque and food.
Who is the right person for getting Sealants?
Because of the likelihood of developing decay in the depressions and grooves of the premolars and molars, children and teenagers are obvious candidates for sealants. However, adults without decay or fillings in their molars can also benefit from sealants.
Longevity of Sealants
Sealants can protect the teeth from decay for up to 10 years, but they need to be checked for chipping or wearing at regular dental check-ups. Your dentist can replace sealants as necessary. It is also possible for decay to get under a sealant that is starting to wear out. Your dentist will be able to diagnose and find these areas with the help of dental X-rays. Appropriate treatment, usually either a new sealant or a small filling, can then be provided before the problem progresses.
