Fluoride is a mineral that helps prevent tooth decay in between professional cleanings. It can be applied to the teeth through highly concentrated gels, rinses, foams, or varnish. However, in children six months or older, it is best not to give them any kind of mouth rinse because they are more likely to swallow it. Therefore, children undergoing a fluoride treatment are more likely to receive the gel form.
Fluoride treatments will last for a few hours after being applied, usually disappearing from the surface of the teeth after being brushed away. However, the highly concentrated solution will be absorbed into the teeth before the patient brushes or eats, with the effects lasting at least three months. Therefore, the family dentist will likely recommend a treatment three times a year or during each routine cleaning.
