Good bye putty, hello digital scanner! We utilize advanced 3D photographic scanning technology to eliminate those dreaded impressions.

Retaining your new smile is critical for a lifetime of benefit. That is why we help you protect your investment by offering free retainer replacement if they are lost, broken, or if your dog eats them!

Patient Reviews

Patient Reviews
"Dr. Arnold takes her time and makes sure everything is perfect from the moment you walk in the door to the time you leave the chair. She is very thorough and precise with her treatment. The environment at Arnold and DeSantis is happy and energetic. Highly recommend Dr. Arnold."
Patient Testimonial

"Dr. Arnold and staff were very friendly and professional. Dr. Arnold's exam and recommendations were very thoughtful, using her own expertise in certain areas, and deferring to the expertise of other physicians in their respective areas. I will definitely keep seeing Dr. Arnold and have already recommended her to a physician and a friend."
Patient Testimonial

"Excellent care and service! Dr. Arnold explained my child's orthodontic issues in great detail and did not try to sell me on services that were not needed at this time. Very appreciative that her best interest was put before their wallet!"
Patient Testimonial
