Teeth pulling

I have an Autistic, 8 year old little guy that has pulled two of his growing in permanent teeth. We have tried Chewy Tubes, and giving him chewing gum to keep his jaw moving and finger out of his mouth. What seems to happen is that every time he is alone for any given reason i.e- in his room at home, in the bathroom at school, bus.. He takes advantage of the unsupervised time and, yanks at his tooth. I was hoping someone can share any suggestions on what else we can do to stop this kind of behavior.
