Fluoride contributes to calcification of your pineal gland. That is where your brain produces its melatonin which helps with sleep induction.... It shouldn't be surprising that there is a increase in insomnia in modern day life.

Another source of fluoride that people don't realize is processed food that gets made with fluorinated water. The sooner we get it out of the water the better.

People can always choose to brush their teeth with flourinated toothpaste if they feel that it is beneficial for their dental hygiene
