I don't think I have any more information that could help you but I do not see severe bone loss in the x-ray. Some of the deeper pockets can specifically form around UNERUPTED or partially erupted wisdom teeth, so yes, removing all 4 of them may help your situation. Since you do not use them to chew, they will not be missed.
Thanks Doctor
A couple more questions if you don't mind,
1. Two of the wisdom teeth (on the upper side) have not emerged, and the dentists believed that they might not emerge during my lifetime, can I ignore them if they do not emerge?
2. Would I feel pain or notice any symptoms to indicate that it's high time for extraction of wisdom teeth has come? Since I don't want to extract them now.
3. Would unextracted wisdom teeth worsen the periodontal disease?
BTW,
1. I have reverse bite , if I don't correct it , would it mean more likely loss of teeth in the future?
2. I also have buxism (grinding teeth during sleep), I have custom made a mouth guard, is it the ultimate solution to the problem?
