When Is Fluoride Intake Most Critical?
It is certainly important for infants and children between the ages of 6 months and 16 years to be exposed to fluoride. This is the timeframe during which the primary and permanent teeth come in. However, adults benefit from fluoride, too.
New research indicates that topical fluoride — from toothpastes, mouth rinses and fluoride treatments — is as important in fighting tooth decay as in strengthening developing teeth.
