Dental sealants are incredibly beneficial not only for children but also for teens and adults of all ages! That said, it is not wise to look at sealants as 100 percent protective. They do not diminish the value of daily oral hygiene. Even after getting dental sealants, it's imperative to brush your teeth every morning and night, and also to floss every day. Remember, dental sealants seep into the deep grooves on the chewing surface of molars. Brushing and flossing remove the bacteria and acids from the areas around the plastic caps, right down to the gum line.
