<s>[INST] Hello, I have had a bony lump on my jaw below a tooth broken off at the surface for some time now. It didnt hurt and would get larger and smaller. But overnight that size of my face has swollen. It does not hurt like abcesses I have had in the past. I am wondering what is going on. [/INST] Hello and welcome. Thanks for sharing your concern. Please understand this fact that it appears to be an abscess only. Hard board like swelling could be cellulitis too.it is a kind of long-standing infection of spaces in the jaw. Please visit your dentist soon get it thoroughly examined and start with your antibiotics and analgesics soon. Do not ignore as prolonged delay might cause Chat Doctor. Hope it helps. Thanks. Take care. </s>
