Sensational Smiles has dentestry figured out. Every staff memeber is friendly and helpful. The hygienists do an excellent job with cleaning, encouraging better home cleaning, and interfacing with the doctors about my visits. The doctors are friendly, knowledgeable, and are always willing to listen to my concerns. They have awesome technology that can make new invisaline retainers in office as well as being able to scan a cavity and create a perfectly fitting filling same-day. I'm always impressed. Thanks!

I’ve been coming here for 2 years and recently needed a crown, my first, so scheduled the appointment. Years ago a dentist didn’t numb me enough and caused a traumatic fear from that point forward. Brenda and Dr. Benson were aware of my fear. They were careful, patient, caring, took extra precautions and made it their goal for me to relax and have a positive experience today. I will say I recommend Sensational Smiles to anyone who is looking for a top notch dentist. The staff is friendly, knowledgeable and on point with answering questions. I always leave smiling. I am truly thankful to have finally found a dentist I am 100% happy with!!

I’ve gone to sensational smiles for years now. Even with SS being out of network for me, I have kept coming back all this time and will continue to come back just because of the people who work there.
Dr Feiock, now retired, and my dental hygienist Laura have always made the trip worth it every time. These two always managed to make what would be a boring checkup instead a visit filled with laughs, reminiscing, and all around good times.
If you want people who genuinely care and are happy to see you, you can’t go wrong with sensational smiles.

Olivia, one word, WONDERFUL. I do not know if a kinder soul has been put on this earth. And what a sense of humor! Dr. Benson, as well, so patient answering my questions and ensuring I comprehended and understood the procedure(s) and what will happen. If there were no Batman and Robin, this would be the OG dynamic duo. Thank you for making the one crown a reality within my short timeline.
- Kerry N.
Amazing team, top-notch care. Not a patient of theirs, but they worked me in for an emergency procedure during a cross-country drive. Everyone, from Tara and the office staff, to Dr. Swingdorf and Dental Assistant, Brie, were the most welcoming and friendly folks you could ask for. Patient, informative, and professional in every sense. If I didn't live 1500 miles away I'd be their newest regular patient. Thanks for turning a tough day into a pleasant experience!

I have always had a lot of anxiety when it comes to dental work. From the moment I walked in, every person at Sensational Smiles made me feel comfortable and welcome. Brenda who assisted Dr Swingdorf, was so gentle and walked me through everything, easing my anxiety. I’m truly grateful she was there, I will always ask for her, she made me feel right at home. Dr. Swingdorf was very kind, explained everything and has a very gentle touch. I had a root canal and crown and have had no issues with any pain during or after. I’m am very grateful to have found this dental office!
- Amy N.
Sensational Smiles scheduled and saw me same day after I chipped some teeth. Everyone here is super kind and welcoming and take the time to make sure you’re comfortable. Jodi was taking care of me alongside Dr. Anderson and they both made the situation a lot more bareable. Thank you both!
- Jesse M.
Brenda did an amazing job going above and beyond to answer all my questions. She educated me on ways to better care for my teeth.(night gel, mouth guard etc) She made sure i had all my questions answered and i was comfortable during my visit.(even small details like the music) Brenda exceeded in all ways. Amazing customer service!

I had a wonderful experience with Katie and the dental team at sensational smiles. I was extremely anxious about going since I had not gone in years to a dentist, and they were very supportive and helped me feel at ease throughout my visit which was very helpful.
