well, interesting information here. I have heard of none of this except ENT told me in the beginning that he might lose all of his teeth. Dentists and doctors are an hour apart so no connection whatsoever...it's rural Iowa. I will mention it to him to bring up to nurses on Monday. He can barely open his mouth as it is. Big guy 6'3" and barely can open his mouth! Then me, a tiny 5'2" with a huge open mouth! thanks for the information!
