Ok I have had a tooth pain for years and I have also had a number of symptoms for the past 6 years. I am wondering if theres a chance that my tooth is infected/cracked/dead/cavity? My first dentist looked at it and said theres no cavity so theres nothing wrong. Some of my symptoms are: Headaches around my eyes,temples,face,neck and head. Lightheadedness or brain fog, depression, anxiety, weakness or fatigue, sinus problems and allergies, posture problems, bacnk aches and pains, tooth pain, weight gain problems, breathing problems, lazy eye, low sex drive, fullness in the ears, low grade fever. These are some of my stronger symptoms. Does anyone think they could be related to a damaged tooth?
