Dr. Sweeney and team you are the Dental gods. Best dental experience you can ask for. I have had a crown on my front tooth replaced 3 times by 3 different dentist and it never looked right. With still some hope left that I could get a nicer crown I came to Dr. Sweeney and y’all he achieved beyond what I expected. My teeth are beautiful, I can confidently smile again!

Never thought I would look forward to a dental appointment after decades of suffering from my gripping phobia of dentists. The staff is so kind, attentive and comforting. Dr. Jordan is an angel. For the very first time, I trust my dentist and this process entirely. This is the most relaxing place and I’m beyond grateful that I found it. Austin Dental Spa has been life changing for me.

Going to the dentist for anything other than a cleaning takes a lot of trust and confidence in your dentist. And that is not easy to feel. I recommend you visit Dr. Sweeney – you’ll be so glad you are in his care. His standard of excellence ensures you are informed, comfortable, and that you’ll receive the best dental care possible, and his kind and competent staff are just the same. When I visit Dr. Sweeney, I know I am going to receive the best care.

Dr. Sweeney is an artist, and a lovely human being. I was referred by our orthodontist, who recommends all of his patients that need cosmetic dentistry to this practice. The staff is amazing, they truly operate as a team, and the added bonus of complimentary hand and foot massages during treatments is incredible. I’m a patient for life now and highly recommend this business.

From the greeting when you walk into the door to your visit with Mark as he checks on the health and welfare of ever patient, you cannot find a more caring and professional group of people.
