Speaking of dental problems, I just had some cavities filled. All of them were due to Actiq. Needless to say, I do not take Actiq anymore. I now take a different b/t med.
I've never had any cavities before. I always brush my teeth several times a day, but that Actiq is just full of sugar. Don't get me wrong, I'm not knocking the Actiq at all! It's a great pain reliever, but you just have to be very, very, diligent about your oral health care. If that means going to the dentist more than twice a year, then do it.
Also, you may want to go to a periodontist for a very deep cleaning. It's not pleasant, but it gets all that gunk out that a regular cleaning cannot.
All pain meds make your mouth very dry. So, it's very imperative to have those check-up's and brush, brush, brush!!
