Calgary is fluoridated
"...up to 40 per cent of very young children have cavities, and that figure is “increasing definitively,” says Dr. Sarah Hulland, a pediatric dentistry specialist in Calgary." (Canada)
"In dentists' offices in the past five to 10 years, we've seen a progressive increase in cases of children aged (up to) five with rampant decay,” she says. “And we know that as they age, they have a huge risk of future cavities if it was an earlier problem.
As with childhood obesity, diet is at the heart of the issue."
