Dear Doctor Mark, I tried using a new toothpaste called Regenerate as I tend to drink too many acidic drinks and was surprised to find it cured my sensitivity. Is it ok to use the toothpaste long term or should you alternate it with normal toothpaste? Also are there any issues about using mouthwash when using this product, i.e. will it interact or undo some of the benefit? Sorry if my questions are not very complex, but my dentist did not know. Thank you.
