@linda1976 I have experience with zirconia dental implants on front teeth. I also have some cervical neck issues and have had a fusion of C5/C6 in addition to thoracic outlet syndrome which is a physical compression of nerves in the neck and shoulder. It's tighter on one side and can pull my jaw out of alignment. That does generate some pain directed to the teeth and jaw or my face. Sinus issues do also come up. I treat those with Mupiroicin ointment inside my nostrils and that clears it really fast. I feel like my teeth have orthodontic braces moving my teeth if I get sinus infections that cause some inflammation. I tend to get that moving into my lungs, so I always want to catch it early and treat it. My dentist was a holistic biological dentist and retired , so I'll be finding a new one.
