Dental sealants are a thin coat or plastic coating painted onto the chewing surface. The dental sealants quickly bond with the grooves of the teeth, it will form a protective shield over to the enamel. Deantal sealants can easily prevent cavities for many years, this shield will cover the cavities that will block all the germs and food to enter into the cavities. The tooth enamel does not contain any nerve so it does not require any numbing, after this process finishes you may eat, drink because dental sealants are a quick and painless way to prevent cavities. For a few days, you will feel odd while biting some but after few days you won’t even know the sealants are there in your teeth. Dental sealants are sometimes used on permanent teeth as well if they have grooves or pits, this helps to protect the surface. The sealant can be clear or the color of the sealant depends upon the sealant that is used by the dentist.
