Our Services

Dr. Nantz and his team are here to help you achieve straighter, healthier teeth. Our practice is equipped with state of the art technology, such as the iTero Scanner and digital x-rays. We provide traditional orthodontics as well as Invisalign.

Orthodontic care can help correct mis-aligned teeth.


For most patients, straighter teeth mean a terrific smile. But did you know that properly aligned teeth are healthier? Overlapped, crooked, or rotated teeth create a daily cleaning challenge.

Traditional braces are an option for straightening teeth.


Braces might be considered a rite of passage for young people, much like getting a first driver's license. An array of wires, brackets, and springs provide combinations for numerous treatment scenarios.

Invisalign teeth straightening is less visible than most orthodontic treatments


For ultimate camouflage, tray or aligner systems render a modern straightening method. Designed with software and 3D digital models, a series of clear plastic trays produce the straightening results.

J. L. Nantz, DDS

Dr. Nantz’s interest in dentistry began in high school while observing in a family friend’s office. Here, he learned how significant an impact a beautiful smile can have, not only on a person’s self-esteem but in how others view them. Each patient is his number-one priority, and they will have his undivided attention at every appointment.

Dr. Nantz received his Doctor of Dental Surgery degree from Creighton University in Omaha, Nebraska, and completed his General Practice Residency at the University of Texas, Houston, before earning his Certificate in Orthodontics from the University of Nevada, Las Vegas. Before entering his orthodontic residency, he practiced general dentistry for three years.

My family loves Dr. Nantz and his team! We are always greeted with smiles and just great personalities. My 8 year old looks forward to her visits.

I went in for my 10 week check up and everything went really fast and on time! Felix was nice enough to explain everything that was going to happen to my teeth. I really like that he did because now I know more and it made me feel very comfortable to know what to expect. –Sara N. This review was posted on Google

I like coming into Dr. Nantz's office. They all make me feel comfortable, and I really look forward to spinning the check-in wheel. And I try to collect as many points as I can so that I can win cool prizes. Having braces may not always be the best, but they make it fun. –Carson B. This review was posted on Google
