In 1988 I had an adult friend who had NO cavities. His father was a
dentist. I asked him how he did it, did he brush after every meal? no.
Did he not eat sweets? no. What happened was his father coated his
teeth (and did flouride treatments) religiously every 6 months.

Now I have met someone else with no cavities. Her father was an
orthodontist. He coated her teeth all through childhood and
teenagehood. Result, no cavities.

Why dont dentists coat EVER childs teeth, especially teenagers, every 6
months?????
