I am so following your posts as I am in the same boat as you are with my teeth. I had 10 teeth removed before I started chemo and radiation well over a year ago. NO ONE including the oncologist, ENT, my dentist or family practice doctors ever mentioned fluoride trays or HBOT treatment and still they have not. I have only read about it on this site. I am using Prevident 5000 toothpaste as well as fluoride toothpaste and warm salt water rinses. But my remaining teeth are in sad shape. You are doing better than I am as you have consulted with a dentist. I tell myself every evening to call and make an appointment but yet the next day I put it off again. I still have the feeding tube in place and therefore do not have to rely on the teeth for much (horrible excuse I know) but, am just so appalled at even letting anyone see in or touch my mouth. I know the insurance struggle is going to be massive. We are still even fighting for reimbursement on the 10 extractions. I too am planning a vacation with my husband and our grown up daughter and son-in-law, a week long cruise. It is scheduled in January. I Am hoping to wait till after the vacation to get going on the teeth issue but perhaps it is just an excuse for me to not make that appointment phone call. Please do keep us posted as to how you are doing and the treatment plan they suggest to you.
