Fluoride helps harden the tooth enamel and makes it more resistant to tooth decay. A small cavity can be stopped and may even be reversed by the remineralization process enhanced by fluoride.
Typically fluoride can be delivered to the teeth in two ways: topically (direct contact on the teeth) and systemically (enters the blood stream).
Dental sealants act as a barrier, protecting the teeth against decay-causing bacteria. The sealants are usually applied to the chewing surfaces of the back teeth (premolars and molars) where decay occurs most often.
