<s>[INST] Hi, I wonder if you can help me. I notice a hard lump on the right side of my lower gums about the size of a large pea, it has been there for about three or four years, it doesnt hurt, lately I notice another little one growing on the other side of my mouth in the same spot as the first one. What could these be? I am extremely worried. Thank you in advance for your help. [/INST] Dear friend. Thanks for sharing your concern. Bilateral swelling in your lower jaw could be due to exocytosis, or bony prominence in that area. An intro oral periapical x-ray can help you to differentiate between a hard tissue swelling or soft tissue swelling. Please mention if you are taking any antibiotics?also mention your general health in your history? Meanwhile maintain good oral hygiene and wait for x-ray results to come. Based upon that further diagnosis can be made. Hope it helps. Thanks. </s>
