I was very pleased with Dr Yamaguchi. She instilled a sense of confidence in me by her excellent explanation of what issues may be present and how they would be addressed. Her effort to support my decision to save the tooth, even though I understood that it would not be a long-term fix was appreciated. She was very skillful in the wirk she did and I did not experience any discomfort during or after the procedure. I would enthusiastically recommend her to anyone needing endodontic services.
