Hell's teeth again

More problems with the crown, or so I thought, so off to the dentist again. After getting me to open and close my mouth several times, scrutinising my teeth and my biting action and fiddling with my jaw the dentist decided that my bite is fine, as are my teeth. He says that he can see nothing wrong and that maybe I will have to put up with it or maybe it is a sinus problem. I am pretty sure that when I go to the osteopath, who has been treating the sinus problem, later in the week, that she will tell me that it is not - it's a dental problem.
