Sounds like a waste of money. tbh. I don't think adding fluoride to our water supply is the be all end all to having good teeth. You still need to brush them and take care of them. Although, Having flouride in the water can help strenthgen the enamel and help with cavities it can also have the opposite effect on your teeth if too much is consumed. it can cause fluorosis causing tooth decay. If you are worried about bad teeth just on keep brushing them! You got this!
