Problems with my turbos/bite blocks

My turbos have worn down and I am contacting my lower brackets when biting

A: try to be careful when biting, try not to bite tightly together. Usually when you are relaxed the teeth are not in full contact anyway.

I have lost one turbo from one side but the other one remains on the other side, does this matter?

A: you should try and bite directly on to that one turbo and try not to slide on it. Even though it will feel strange biting on just the one, it will still be helping free the bite.
