The limited orthodontic feedback mentions painful bracket sores with little weekend support and delays getting adjustments made because the ortho team was only available on Fridays.

I went to see Dr. Marc at Cornerstone in May of 2025 and the orthopedist D. Z+ because my front teeth were worn down and my bite had collapsed. They put together a plan for me to wear Invisalign for a year and then get crowns on the front upper and lower teeth. They warned me that my teeth would look worse before they got better but I had to trust that I would be happy with the results. In May of 2026 I was able to get temporary crowns to determine the fit and make adjustments and now on July 29 I received my final crowns. They look amazing. Both doctors were very easy to work with and are so precise about all the details that go into a very difficult restoration job like this. I am so very happy with the results and would not want anyone else to have done this for me. Thank you for this life changing experience. Below are the before pictures after the Invisalign treatment and before the temporary crowns and then after I received the final crowns!
Richard was the assistant who took care of me.. he knew exactly what he had to do and got it done quickly, politely, and satisfactorily. The other employees i dealt with were also very friendly and knowledgeable.
Didn't exactly love it but great staff and everything well explained and relatively pain free. Dr. Matt is the best.
This dental practice is AMAZING!! My family has been going here for years and will never change!! They are wonderful and very patient with the elderly!! ESPECIALLY NYE and RICHARD!!! They were wonderful and very patient helping my grandfather who’s not mobile and very gentle!!! Can’t say enough good things about them!!
Dr. Dan and John replaced my front crown today (6/9). They created a relaxing atmosphere, handled all my questions patiently, and were very professional. Dr. Dan is always excellent. John exemplifies the customer service and genuine care that's lacking in so many businesses. I'm thankful the Westside has such an amazing dental facility and fantastic staff.Thank you!
