A 40-year-old member asked:

is there any proof that fluoride in drinking supply is bad for your teeth?

No: Fluoride decreases cavities by 60%. Overfluoridation causes extra white spots and occur in children by eating toothpase not generally from fluoridated water(use only a pea-sized amount and only at age that they can spit well - 3 or over). Healthy teeth are crucial to overall general long-term health. Fluoride does not cause cancer.
Dr. Mark Diamond
Pediatrics 46 years experience
Overdose only: Dr orton's answer is excellent. Since the mass introduction of Fluoride in the 1950's, the percentage of children recieving Fluoride and having no cavities has skyrocketed, compared to children not exposed.And all data reports no cancer issues despite skeptics.

Where can I purchase mouth guards for grinding teeth?

Dr. Shawn Murray
Dentistry 15 years experience
Mouth guards: Almost every dentist can make you a custom mouth guard. You shouldn't buy a mouth guard that is not made for you specifically or it can cause problems. Just like one size fits all shoes aren't a good idea.
