All sources of water have a natural amount of fluoride. The right amount of fluoride in drinking water helps protect against tooth decay. Drinking water includes all water used to drink or prepare drinks (including infant formula) and the water we use for cooking.
For good dental health, Health Canada recommends that drinking water has 0.7 mg/L (milligrams per litre) of fluoride. However, drinking water with too much fluoride can affect your health.
There are guidelines that set the highest level of fluoride in water that is safe for us to drink. This is called the maximum recommended level. These guidelines help protect us against possible health effects caused by too much fluoride.
Depending on your age, it may be safe to drink water that has fluoride levels higher than the maximum recommended level.
Anyone can use water with fluoride levels above 1.5 mg/L for washing dishes, laundry, handwashing, and bathing since fluoride can’t get through your skin.
Drinking water that comes from a well may have fluoride levels that are too high. Depending on who is using the water, if your drinking water has more than 1.5 mg/L of fluoride, you may need to take steps to protect your health. Learn more about
testing your drinking water in Alberta.
If your drinking water has too much fluoride, use drinking water from another source such as treated public water or bottled water. These water sources have fluoride levels of 1.5 mg/L or less.
You can lower the level of fluoride in your drinking water supply with:
Choose equipment that is certified by NSF or the American National Standards Institute (ANSI). Follow the manufacturer’s directions. Don’t use pour-through or pitcher-type filters as they don’t remove fluoride.
You can also combine your water supply with water from another source to lower the level of fluoride in your drinking water.
