<s>[INST] The other day I started to feel pain on the bottom right side of my jaw (like my wisdom tooth was coming in). Recently, it has been hurting, and the gum seemed swollen. I just assumed that was the tootChatDoctoring in. I was just chewing gum where this is happening, because it hurts, and a felt a popping sensation. I do not see any of the tooth exposed, however, puss and blood were coming out of the gum. [/INST] Hello your condition is called as peritonitis. Pericoronitis is a condition where there is inflammation of gums around erupted or partially erupted tooth. It is most commonly seen in wisdom tooth (third molar).  This generally happens when there is no sufficient place for the tooth to erupt in the jaw. But the tooth tries to come out of the jaw. This results in partial eruption of tooth, and because of which there will be food accumulation and more plaque accumulation in that region resulting in inflammation in that area. It can also get infected easily and can cause abscess in that area (abscess =collection of pus). This infection can be painful and there may be difficulty in opening mouth and swallowing food. Do visit dentist, depending on severity antibiotics may be prescribed, once acute condition subsides a X-ray will be taken to ascertain the position of tooth. Based on X-ray findings and your age it will be decided whether it will erupt or not. If the conditions are favorable for eruption then a simple procedure is done to remove gums covering tooth and there by allowing it to erupt. If it is not favorable for eruption then it has to be extracted. Take care </s>
