[|AI|]  Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint a dark purple lump next to molar tooth can be due to a dilated vein also known as Varicose vein or a Varix. The lump might be due to formation of a small blood clot that got lodged in that area forming a Thrombus. It is not AA serious condition and will not cause any serious problem. It can gradually reduce in size on its own. If it is not ruled out as the cause other causes can be like mucous cyst or Muscle, Hematoma or a Hematoma. Confirmation can be done by getting a clinical evaluation done by an Oral Physician or an Oral Surgeon. Hope this information helps. Thanks and regards. Chat Doctor.
