 [ Symptoms ] does acupuncture help with fibromyalgia [ Disease ] according to your x ray and the area marked it looks like there is widening of periodontal ligament space that is clear indication that you have infection that is causing pain and sensitivity to hot and cold so my suggestion is that you should get the root canal treatment of the tooth done followed by a script of antibiotics like amoxicillin and anti inflammatory painkillers like ibuprofen it should be followed by capping of your tooth this will be the most appropriate line of treatment hope this helps regards
