I also had an abscessed tooth that would not heal w/antiobiotics, no matter how strong. I found immediate relief with Pyrogenium...I strongly recommend it... I used I believe 9c for a few days and it worked miraculously. I also had bone loss - the dentist however filled in the bone with some fake bone material they use for such things...if your dentist doesn't know of this, call around...My dentist is a Dr. Zenk in Inver Grove Hts. Minnesota - if you wish to call him (endodontist). Good luck
