Best dentist I've been to and I've been to plenty! High quality, personalized care. I recommend them to everyone and anyone who will listen! They work well with children, people with dental anxiety, adults, and everyone in between. Dr. Kolten Astle is an exceptional dentist. I've seen him save teeth that other dentists would pull, make them look brand new and greatly increase folks' quality of life by doing so. If you need to get your smile back, you need to go here!

Exceptional experience here with Dr. Kolten and his staff! I had a very sensitive tooth that needed a crown. Dr. Kolten treated the tooth with a desensitizer before he was able to do the Same Day crown! I’ve never been to another dentist that used a desensitizer before. It was a game changer. And being able to get my permanent crown in the same visit was awesome!! They also brought me a big warm blanket while I waited for my custom crown. Definitely recommend Legacy smiles to any and everyone!

We had to switch dentists after our previous one was no longer in our network, and it turned out to be a blessing in disguise! The office was able to get us in right when we needed to be seen, and the entire staff was so friendly and welcoming. Dr. Kolten is extremely kind, gentle, and took the time to explain everything in great detail. We’re so glad we made the switch and highly recommend this office!

Dr Kolten had a high bar to reach, replacing the retired Dr Stuart. He has done very well in that regard! My recent Crown was a great example of that. With the technology they use now, little over an hour and it was all done! Hope I don't need another one! But if I do Dr Kolten will be the one doing it!

I was very happy with the entire experience! From the moment I made my appointment I felt like I was in good hands! Dr Kolten was very kind and did an amazing job on both of my root canals! His assistant Ashley also did a wonderful job! They made a great team! Thank you Legacy Smiles I highly recommend!
