I took my sweet time getting one of my tooth fixed and when it was infected I called and was able to get a same day appointment. Dr. Nguyen work is amazing because there was minimal amount of pain (besides the infection of my gums)

I was shocked at how good the dentist and service was. Having to leave my other dentist due to expenses Upland Dentistry really suprised me. I will continue to see Dr. Dat Nguyen and my daughter also.

We were looking for a family dentist that has the latest technology, great training and can do all the necessary treartments with out sending us to a 'specialist'. We found the right place. We have sent other friends and family and all have had a similiar experience. (Also very price competitive)

I needed an emergency root canal and I had never been here before. My dentist was out of town. The Dentist called me to tell me to come in right away because I was pregnant and afraid the tooth was infected. Everyone was so kind and caring and it made me feel at ease considering how much pain I was in. They even called afterward to make sure I was ok because they saw how much pain I had been in. That says a lot because most dentist's will not call you, you have to call them. They were all such wonderful and kind people. I've had my dentist most of my life, and am moving back here from Colorado and am thinking about switching permanently to Upland Smiles. But if you have a dentist but ever have an emergency on Saturday they were absolutely wonderful.

I have been a patient at Dr.Nguyen's Office for over a year. We enjoy our visits and appreciate all the help from him and the staff. The best thing that was done for me was that he removed the ugly staining on teeth and now I feel a lot better.

Again thank you!

My family and I have had a very positive experience with this dental practice. The Dentist and all of his staff are always very helpful, informative and professional. I would recommend this dental office to everyone. We are pleased and proud to have Upland Smiles Dentistry and Dr. Dat Nguyen take care of our dental needs.
