HI Jill, you're welcome! Thanks. I find these links after doing a lot of searching and when you're not well, guess there isn't much else to do. But at least I get a chance to share them on here with others. Can only hope someone gets something out of them.

yeah I don't believe in overbrushing teeth either. perhaps rinsing with water after meals is the way to go, as Dr Judd , rather than brushing all the time. They only need to be brushed once in morning and once at night.
