Supporters of water fluoridation have long celebrated its effects on the growing teeth of young children, citing fewer cavities, stronger enamel, and lower dental costs as benefits. Now, a new study has shown that it's not only the mouths of babes which might benefit from fluoridated water, but those of their grandparents as well. Participants in the study, all adults older than 50, were more likely to report having all their teeth if they lived in an area with fluoridated water. This news will no doubt bring conflict to many middle-aged folks--especially children of the sixties and seventies who might have campaigned against mass fluoridation, citing links to a spectrum of maladies that might be caused by the additive. Would you rather: skip the dentures or risk being involuntary exposed to a substance many consider to be "toxic?" Let us know in the comments.
