In high enough doses the fluoridated water can be harmful and dangerous to your health.
The fluoridated water is good for teeth health but it really should not be added to our city water supply and is not natural or meant to be in drinking water.
Luckily my town has decided to no put fluoride in our water supply anymore because it was deemed to be unsafe in the water since we drink the water.
Excessive exposure to fluoride can lead to bone problems and discoloration of your teeth.
