There are many benefits in the use of fluoride for all ages. For young children, while their teeth are forming, fluoride joins with the enamel surface and makes it harder and more resistant to decay. For adults, fluoride can help repair an early cavity, by rebuilding the enamel layer of the teeth. And for older adults, it can help solve the problem of root caries or root sensitivity. We recommend fluoride toothpaste for all of our patients.
