Hi Destiny,
I don't know if you read my post on acupuncture, but after quite a bit of research, it is believed that acupuncture can stimulate the salivary gland cells again. Now I don't know how true this is but it may be worth giving it a go.
I think it would be wise though to make sure you are in the clear first. It may be worth your while speaking with a naturopath about this. Good luck.
