A hard lump has formed below the teeth along the outside of the jaw line, right by the pre-molars and molars. It was sore when first developed, but no longer causes any sort of pain, soreness, etc. It is totally hard to the touch, no swelling or movement.
Hello! Thank you for the query. Such lump can be caused by a stone in salivary glands which has moved to the salivary ducts. It is more possible if you have had pain when swallowing. If you do smoke, malignant lesions like mouth cancer or tongue cancer should be also considered. I suggest you to consult palynologist with this issue. In case of stone, it needs to be incised and removed. Hope this will help. Regards.
