Water Fluoridation


Fluoridation of Municipal Drinking Water Systems 

by Dr. Jim Chirico, Medical Officer of Health/Executive Officer for the North Bay Parry Sound District Health Unit.

Tooth decay is the single most common chronic childhood disease.Fluoride makes teeth more resistant to tooth decay (cavities). Fluoride is added to municipal water, supplied as a public health measure to provide protection to everyone's teeth. In addition, fluoride is available in toothpaste, rinses, chewable tablets, as well as drops. A dental professional can also apply fluoride to your teeth.

Water fluoridation is endorsed by many governments and health organizations as an effective, safe, and cost effective way of preventing dental decay for people of all ages. Fluoride levels in municipal drinking water are regulated in Ontario under the Safe Drinking Water Act

The Benefits of Adding Fluoride to Municipal Water:

  • reduces tooth decay rates
  • saves an estimated $38 in dental treatment for every $1 invested in community water fluoridation
  • prevents tooth decay for all residents regardless of age, education, or socio-economic status

Based on certain eligibility criteria, the Health Unit offers fluoride treatment to children 17 years and younger.
