Dianne, I'm sorry none of your messages have been answered. I try to answer as many as I can, but if I have no clue, I keep my mouth shut. As far as teeth whitening I would go to a dentist to get information on whitening. I have read where they do not recommend the Crest strips as they can strip the enamel from your teeth. Plus make sure you explain that you have had RAD if that is the case. Right now I'm just fighting bone grafts to see if I can get implants to replace those teeth taken during my surgery. If you want to vent you can always contact me at [email protected]. I try to always answer everyone. But between my job as a consultant, keeping up on the board and answering personal replies, sometimes it takes awhile. Take care. Anne.
