Hi Nicki,
I use my fluoride trays nightly, too. I brush with a prescription toothpaste (has 1.1% fluoride) and use the fluoride gel in my trays for 15-20 minutes. I, too, was fortunate in that I didn't have to have any teeth pulled and I'm doing my part in seeing it stays that way! Tell Tom to keep up the good dental routine - it'll pay off in the end.
Hugs, Nancy
