Dianne.....Sorry you feel like your posts have been neglected but I can almost assure it is not intentional at all. I don't know a thing about tooth whitening so I can't join in that discussion, but if you wanna know about a mouth minus saliva BINGO! you've found the right person! LOL Don't get discouraged from posting because your input is very important, and you never know when some new member signing up will be able to answer you tooth whitening question. You've gotta remember a lot of us don't even have teeth to get white! LOL Keep posting! Sincerely, Donna
