I had a great experience with Dr. Kortebein extracting my 4 wisdom teeth. I had been procrastinating this procedure for some time but after meeting with him and listening to all the options I felt very comfortable knowing I would be in good hands. I decided to do the nitrous gas because I didn't want to completely be out for the procedure. Dr. Kortebein and his team were very kind with making sure I was doing well throughout the surgery. He is extremely skilled, professional, and knowledgeable in his expertise. I couldn't believe how quick he was able to extract all 4 wisdom teeth. I didn't experience any significant pain during or after the procedure which was a plus too. I would definitely recommend this oral surgeon to others who are looking to get their wisdom teeth removed.

Excellent Oral Surgeons. I have gone here several times in the past few years for extractions and each of the oral surgeon's expertise has been outstanding. I highly recommend them.

I have a confession to make: Dr. Kortebein is my brother. However, when he was done extracting the tooth I asked him, "So are you ready?" to which he replied, "I am finished". Pain management is, apparently, his strong suit. That and I really enjoyed, being part Irish, the low-key and friendly staff in Oak Creek. One more thing, his newfangled x-ray setup was very comfortable (no bitewings!).

My experience was terrific! Very little pain before, during and after. The doctor was quick and the surgical assistant kept me comfortable and at ease. I will return for other service as needed.

Dr Kortebein and Staff were absolutely Wonderful in the removal of a cyst between two lower teeth. Thank you ALL for taking care of my problem today

Extremely clean and tidy environment. The dental asst. was professional and most attentive. Dr. Kortebein explained the procedure, applied a topical before numbing my jaw, extracted my tooth and put in 3-4 stitches. His asst. brought in my wife and carefully explained what we had to do at home to make me comfortable. Alissa, the bookkeeper, explained the charges, accepted a deposit and said she’d be sending the bill in to my insurance co. Total cost was $307, which was very reasonable. I will certainly recommend Oral Surgery Associates to friends in need of their services.
