This Endodentist came to an erroneous conclusion when diagnosing my mouth pain. Had I not gotten a second opinion from a highly experienced and respected Endo, she would have performed unnecessary root canals, and I would still be in pain and out many thousands of dollars. All my teeth are vital and healthy; there was no reason for her to suggest root canals. The problem has been subsequently diagnosed and treated effectively and inexpensively. I will not return to Dr. Jacobson.
