Fluoride is essential in maintaining strong, healthy teeth. An in-office fluoride varnish can be painted on your teeth, making teeth more resistant to the breakdown from dental decay. It is a very quick application; there are no food or beverage restrictions after it is placed. Even though your dental insurance may consider this as an elective service for adults, patients of any age are welcome to the service. Daily use of fluoridated products has been shown to reduce the occurrence of decay in patients of all ages. Fluoridated water is essential while teeth are developing. If a child is consuming non-fluoridated water, consult with your dentist as to whether or not fluoride supplements are recommended.
