What to do if i had a root canal was in pain every visit but the last visit my face swelled up went to the specialist?

Communication.: It sounds like your root canal involved an active infection; this is a very common reason to complete a root canal. IF YOU HAVE ACTIVE SWELLING YOU PROBABLY NEED TO BE ON ANTIBIOTICS and/or anti-inflammatories. Stay in contact with your specialist and your dentist. Let them know what's going on and expect answers or at least a defined plan to manage your concerns.

Endo second opinion: In many cases, seeking a second opinion is not only warranted, but necessary. Unless your disease is life threatening and requires emergency care, it is never a bad idea to seek a second opinion. Getting a second opinion helps you feel more confident about your diagnosis and treatment plan. See a board certified endodontist for your treatment options..

Endodontist: It is possible that the infection has not resolved. Your endodontist will determine if you need antibiotics to treat the swelling. Feel better soon..
