Very thorough and professional in the consultation visit giving me confidence in selecting Dr Kortebein to go ahead with the wisdom tooth extraction, which was completed earlier this week. Procedure went very well. Same thoroughness by both the Dr Kortebein and his support staff. Super follow through providing instructions, soliciting questions, and following up by phone the day after. Also worth noting was that there was a question on an adjacent tooth condition and potential extraction necessity. This second tooth concern actually drove the need for the wisdom tooth extraction (a 64 year in the making issue). Upon removal of the wisdom tooth, only normal dental repair will now be required on the adjacent tooth. Hopefully I will never need an oral surgeon again.....but if so I will be returning.
