Thanks for the very thorough response, Gary! I think we just need to find a more competent general dentist. One of my biggest concerns with my husband's regular dentist is that he didn't fit Mike for fluoride trays, just gave him a Rx toothpaste and said to also use fluoride rinses and come back to see him at 6-month intervals. Seems like most people on the boards use trays and have more frequent check-ups. Your ideas and suggestions are much appreciated and will help us as we interview for a new dentist. Thank you!
