I have always had trouble equalizing my right ear, and have read of many others with this one sided problem. I may have figured it out last night. Thoery: I have a bad tooth on the left side, and have been chewing mostly on the right side for quite some time. It seems likely that the extra jaw exercise would cause the muscles on the right side to be more tense, and even larger than those on the left. Thus making it more difficult to open the right eustacian tube. Do other people with this problem have a tendancy to chew on one side? Maybe some of you Anatomy Majors could lend some insight. Maybe this is a well known fact. Any intel would be appreciated.
