<s>[INST] hello, yesterday I woke up with aching teeth , I assumed from the symptoms the cause to be either dental problems or sinusitis . During the day I have felt slow swelling, payed no attention to it, brushed my teeth trice during the day and gone to sleep. Today I woke up with badly swollen upper lip and aching teeth. Teeth seem to be aching from movement of some sort. Upper lip is swollen and I think there is a lump, main swelling is inside the moustache area of the lip within it. I have little to no cash right now and cannot afford going to a doctor if it is not a major cause. I was at the bar two nights ago, but teeth ached a little before. My first upper right tooth was dislocated during a fight 8 years ago. I hope I gave enough information for you to help me at least to know what is the cause of this. Thank you in advance [/INST] hello and welcome, as you mentioned,your upper right tooth has dislocated 8 years ago,there is chance of traumatic injury occured with the tooth resulting in periapical abscess as well as apical periodontitis. Usually in such cases,root canal treatment is indicated depending on the condition of tooth. The pus has to be drained and curetted, Please do visit an endodontist and get the treatment. analgesics will give only temporary relief. for permanent cure,you must get the treatment done. ANTibiotics has to be administered for the infection underlying. take care. </s>
