They are more susceptible to decay and need extra protection. This is why, sealants are being highly recommended for children and adults. To place sealants on teeth is actually a very short procedure. The dentist first roughens the molar with solution and then the plastic sealant is painted on the tooth. As the plastic dries, it hardens and bonds to the tooth.
Sealants can normally last up to five years and hold up very well under normal chewing.
While sealants are an excellent way to prevent tooth decay, brushing and flossing and visit to your dentist are still essential as sealants do not protect the other teeth or between the teeth. If you are or should be considering sealants for yourself or someone in your family, be sure to Ask Your Dentist.
