Finished my first tooth extraction today, with a bone graph! Both are needed for a future implant on a lower molar. This was an unexpected surgery that came about from tooth resorption. Having a HUGE fear of dental work, ok big dental baby, I happily chose to do this with anesthesia. Great choice! Full comfort, no pain and no remembrance! Now on day 2 feeling good with Advil and hoping for a quick healing! Thank you to the ASO staff and Dr. MacCarthy! He's personable, funny and an excellent surgeon! They really did make everything so easy and pain free. Greatly appreciated. Parker
The service I received from OSA was excellent! Their system for gathering the information needed to provide their service was easy and done quickly on line. The care I received once getting to their office was exceptional! My tooth extraction took much less time than I expected, and the surgeon doing the procedure made me feel at ease. I highly recommended this practice to anyone needing oral surgical care!
I brought my elderly parents here when they both needed to have extractions. The team is excellent. They took their time with us and assisted to move my wheelchair Dad into the dentist chair. They explained each step along the way and made sure my parents were comfortable through the entire process. Dr. Z was great with my cranky/ sassy mom!
I was so nervous to get my wisdom teeth out, but everyone at the office made me feel incredibly comfortable and relaxed. Dr. MacCarthy took the time to explain the different medication options since I was very anxious about being put under. I was able to stay relaxed without being fully asleep, and he even guided me through the entire procedure, which helped so much. I was in and out within an hour! They got me in quickly for my consultation, and I'm already home recovering. The entire team is wonderful, the office is beautiful, and they even called to check on me first thing this morning. Thank you to OSA for helping me get through my fear of having my wisdom teeth removed - I couldn't have asked for a better experience! 11/10!!!
Highly recommend this office! I ended up at OSA after many appts trying to figure out a complex issue. After seeing Dr. Lawler I felt at ease, cared for, and was immediately on the way to solving the problem. He is extremely knowledgeable and proactive with his patient care. The office is professional, clean, and their employees all told me they love where they work.. and they really looked like it. That speaks volumes. I’ll always return here.
