Pain medicine and tooth decay

I recently talked to some friends and forgot one of my issues with my illness. Having to take pain medicine on a regular basis causes dry mouth which leads to dry mouth. This is something that doctors don't tell you. After many cavities my dentist told me what the problem was.

I had to start flossing a brushing more but more important drink plenty of water to stay hydrated. Another thing that my dentist recommended was a dry mouth tooth paste,mouth wash and even a gum.
