Sealants & Fluoride Fluoride is a mineral found naturally in most foods and many water supplies. It is an essential component of tooth enamel. However, approximately half of the United States population is drinking non-fluoridated water. Fluoride can strengthen tooth enamel, help teeth resist decay, and reduce the effects of plaque and calculus. It also can prevent new cavities from getting larger and keep cavities from forming at the roots of teeth in adults whose gums have begun to recede or those who have had periodontal surgery. In the 1970's fluoride cut tooth decay in children by a third. It was around that time that the first dental sealants were introduced, further reducing the amount of decay present in todayês kids. Sealants are a painless technique in which a thin plastic coating is applied to the chewing surfaces of the six and twelve year molars. Unlike fluorides, which mainly protect the smooth surfaces of the teeth, sealants are more effective on the rougher chewing surfaces and deep grooves of molars, where cavities can more easily form. Once the decay process has started, it is too late to apply a sealant as a protective measure. It is also important to remember that sealants do not replace proper oral health habits including thorough brushing and flossing, and regular trips to the dentist. The benefits of fluoride have been well proven. The method or treatment most appropriate for you will be discussed with you during your hygiene visit. If you have any questions, don't hesitate to ask your dentist, or your hygienist! |
