The 1988 adult dental health survey showed that more than nine out of t10 people over 45 had some root surface exposed. Almost all over 65s were at risk of root surface decay. In fluoridated areas adults keep more of their own teeth longer, and have much less trouble with them. Strengthening enamel Dentists used to think that fluoride worked by being taken up and strengthening the developing enamel of children's teeth. However, it is now known that the effect of fluoride on the surfaces of teeth after they have erupted into the mouth is even more important, and that all ages stand to benefit from water flourdation.
Tooth decay can be very painful, and can make teeth unsightly.
It is a preventable disease and is the main cause of tooth loss in all age groups. Prevention means a better quality of life for older adults and less money spent on dental care. The World Health Organisation, the Royal College of Physicians and the Department of Health have endorsed water fluoridation as safe.
