<s>[INST] I have to have root canal on a molar. But i had foot surgery on both feet nearly 4 weeks ago ( bones broken and pinned, bunions shaved etc). My tooth is so painful that it only goes away when standing and after 2 endones. Would ibuprofen be better and can I take it now 4 weeks after surgery? [/INST] Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint in case if you have a severe toothache it can be due to deep decay in tooth that is involving the nerves and irritation and inflammation of nerves cause severe pain. The first thing that you should do is to consult a Dentist and get evaluated, and he can do an IOP AR [x-ray] to rule out the exact cause of pain and advise treatment accordingly. As of now you can take Ibuprofen while if pain is severe you can also take higher painkillers that can relieve severe pain like Tramadol or Motorola. You should get the tooth treated if it can be saved Root Canal treatment can be done followed by antibiotics and painkillers while if there is gross decay extraction is advisable. Hope this information helps. Thanks and regards. Chat Doctor.  </s>
