<s>[INST] I have had a toothache for 6 days now.  Bottom tooth, left side, third from back.  It hurts to touch or when I rinse my mouth. and general achiness.  I am using T1 for the pain. Now my jaw bone under that tooth is sore and I have a numb feeling there now.  I have also had nasal congestion/cold for the same amount of time.  Thoughts? [/INST] Hello and welcome to Chat Doctor, toothache indicates bacterial decay or infection in the tooth that involves the exposed tooth nerve tissues.  Such infected tooth needs to be treated by a root canal procedure, so please consider getting the treatment done by consulting a dentist.  You may need an OPG radiographic examination done for your teeth to confirm the spread of infection or to rule out the exact cause of the pain and swelling. I would suggest you to start with antibiotic Augmenting 625 mg along with analgesics like diclofenac two times daily for 3 to 5 days.  I hope this helps, take care. </s>
