Michelle -
You are not alone! I have had an obturator for almost two years now (am in the process of having my definitive one made). I, too, have teeth that have shifted on my "good" side, making chewing difficult (the teeth don't grind well). It's a drag, but I live with it. All in all, the obturator is doing well by me -- my speech is good, swallowing is mostly good.
Ask any questions you have -- there are a few of us on here who would be more than happy to answer!
