The entire experience was exceptional. I checked in and waited for about 10 minutes before the hygienist was ready for my cleaning and polishing. The dentist then came in to thoroughly check my oral health. I was informed that I needed a crown, so I paid the deposit and scheduled the appointment. Both the dentist and hygienist were extremely friendly and readily answered all of my questions. The front office staff was also very friendly

Appletree Dental North have always done great work for me in the twice yearly checkups, for new & replacement fillings & crowns. Alisha did a great job on the teeth cleaning on January 2023. Dr. Derby has put in 4 crowns, I have had the crowns for the past 12 years with no problems.

I have been going to Appletree for over 5 years now. Never had a negative experience and the staff is always friendly. I also got my whole family to go to Appletree. My dental hygienist has changed twice, but no matter who I get they are always friendly and ready to answer questions for me.

I originally had an appointment for tomorrow. But I was unable to sleep due to a horrible toothache. I called Appletree dental and they were able to move my appointment up a day!The dental assistant took lots of notes about my tooth pain to ensure the dentist had all of my issues incase I forgot something when explaining to the dentist. She also asked me multiple times if I was okay to continue X-rays or if I needed a break due to the pain.Once we got all the X-rays done Dr. Tho Alexis Nguyen, DDS came in and met with me and we talked abit about my tooth pain. She did an exam and explained why I was having so much pain in that area. We came up with an action plan. And got me some antibiotics and pain meds. She even said I could call her if I got home and had any questions.Once home the meds worked for about an hour I called Dr. Nguyen to see if there was anything else I could do for the pain. She gave a suggestion and asked me to call her tomorrow to see how I’m doing.I have never had a dentist go above and beyond for me like this and genuinely caring about how I’m feeling. I will definitely be going back for all my dental needs.
