Do meds really have an impact on your teeth? I've noticed since I've been on meds I get a lot more cavities that need filling and even needed a root canal. Is it possible the meds are causing this?

In other news: any predictions for the fight tonight? I want Pacquio to win but the odds are going towards Mayweather. I was planning on staying up for it but it starts after 4am here so feck that!
