Forty-four public water supplies, in seventeen health authority areas have so far been fluoridated. Since most of these supplies have been fluoridated only for a short time it is yet too soon to have evidence of the effect of fluoridation. An interim study, in a limited area which has been fluoridated since 1964, indicates that there has been a beneficial effect on children's teeth in this area.
