No, fluorides such as those used in fluoridated water, fluoride toothpaste, and fluoride mouth rinse help prevent decay on the smooth surfaces of teeth. However, fluorides have less effect on the rough, pitted chewing surfaces of the back teeth where food particles and decay-producing bacteria are trapped. Sealants, however, are only effective on uneven chewing surfaces. For maximum benefit, sealants should be used as part of a child's total preventive dental care. A dentist should examine the child's teeth and gums regularly to check bite, tooth eruption, and the condition of both hard and soft tissues.
Sealants help to maintain sound, intact teeth.
Decay destroys the structure of the tooth. Each time a tooth is filled or a filling is replaced, additional tooth structure is lost. Amalgam fillings last an average of six to eight years before they need to be replaced. Appropriate use of sealants can save time, money and the discomfort associated with restorative dental procedures. If decay and decay-causing bacteria are trapped beneath the sealant, they will stop multiplying.
