[|Human|] Hello: In October of 2010 I underwent a root canal and have had persistant swelling of a submandibular salivary gland since that time. In Sept of 2011 I was found to have hyperparathyroidism and underwent a minimally invasive parathyroidectomy at UW Madison for a benign adenoma. At that time they biopsied  my salivary gland and told me it was normal. I have had my root canal x-rayed 3 times since and they say it is not coming from the tooth. I had a CT scan that says it is enlarged but no tumor or stone is noted. I continue to have pain, swelling and a very sweet taste in my mouth. When I had the hyperparathyroidism I had a metallic taste in my mouth which has now been substituted for a sweet taste. They have given me the option of removing my salivary gland but I feel like it is still coming from my tooth but no tooth pain? Please help
[|AI|]  Thanks for your query, I have gone through your query. The sub mandibular salivary gland swelling could be because of stone or any bacterial infection or viral infection. Consult an oral physician and get your self examined completely and get an ultrasound and FNAC done to rule out any tumor or any other pathology. There USNO relationship between RCT and swelling of salivary gland. I hope my answer will help you. Take care.
