<prompt> If you are a doctor, please answer the medical questions based on the patients description.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 congestioncold for the same amount of time. Thoughts?  <response>: 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.
