I like Jerry's option. This will help you determine that this is the cause, can be infinitely adjusted thinned smoothed and is a relatively inexpensive process to explore things with. When this solves your problem, you can then decide to continue with it or have any rough areas on you teeth taken down with a bur and polished to a smooth finish. As someone with a minor bit of dental knowledge, I think that the first rule of thumb is to not cut health dentition unless it is absolutely necessary, Once gone, it is gone.
