My Experence with Dr Shannon was negative. My proceedures included root canal, bonding, and many fillings. I had constant pain on my mouth in several areas and after getting no satisfaction from Dr shannon I sought the opinion of other dentists. Aparrently Dr Shannon failed to remove all the decay when he installed the fillings and I had cavaties under most of them. Additionally some bonding he did to fill gaps in my front teeth was causing rot also. I would never reccomend anyone I know going to him. I am now having most of the work re done by someone else and my mouth feels and looks great.
