Appletree Dental North have always done great work for me in the twice yearly checkups. I have had new & replacement fillings & crowns over the years. Dr. Derby has put in 4 crowns. I have had the crowns for the past 15 years with no problems. Hannah did a great job of my twice a year check up & cleaning done on October 2026.

My last appointment was great at the Appletree Dental on 136th Avenue in Thornton! The front staff (especially the Office Manager,) was exceptionally helpful, the woman who performed the cleaning was great, and I always appreciate Dr. Derby, who spends a lot of time with me and fully answers all my questions. They are always happy to provide lots of information and to work with me on my treatment plans. I can't say enough good things about them!

Hannah has long been attuned, it's fun and comforting to be in similar life stage for conversation, and she has long done well with cleaning my teeth. I enjoyed a personable visit with Dr Derby too. We've been here 18 yrs and there was peace today. I enjoyed my cleaning!

When we moved, a family member recommended Appletree, and it was a great choice. The staff is professional and friendly. I found the hygienist and dentist to be gentle and they kept me informed with each step.

So friendly and they do such a great job!!! I loved my previous dentist that I had gone to for years but, sadly, I had to change dentists. I came to Appletree at the recommendation of my daughter, and I couldn't be happier! I couldn't believe the difference in my cleaning...they got literally every little spot off my teeth. I'm very happy with my switch!!!!

My appointment was with Dr. Morret and his assistant Austin. This was the first time I didn’t feel any pain while getting my teeth worked on. Both of them were very knowledgeable, efficient in their work, and just good people in general. Even the lady at the desk was very nice. A solid dental office, will be back

I was a brand new patient that came in with tooth pain. They talked to me about my insurance to make sure I was aware of what I might have to pay out of pocket. The doctor quickly identified an infection and gave me her recommendations. Everyone was very friendly and professional. I felt like I was in very good hands

Our old dentist no longer accepted our insurance so we were forced to find a new dental office to transfer our entire family’s care to. I’m so happy we chose this place! Everyone who works here have been nothing short of welcoming, kind, and knowledgeable! So happy we found them!
