Hi, I certainly think seeing an ENT is a good idea. Infected tooth roots from the upper teeth can go inside the maxillary sinus and cause sinusitis. The mucous cyst could be from chronically inflamed sinuses. However, if you do have an infected tooth, you will still need to have this addressed as dental infections can be potentially life-threatening. Regards.
Hi I went to my dentist and he said the pain will go soon he didn't say anything about an infection but I might go and see a different one just to make sure thank you that private for me as my doctor is not gonner refer me beacuse of what the doctors said
