We Are Quad Cities Compassionate Dentists

Why Choose Us?

Quality Care & Service

Same Day Emergency Appointments

Treatment Financing Options

When we say Quality Care and Service we stand behind that. Each of our team members are committed to your complete comfort. We are aware of your dental anxiety and welcome patients who are afraid of the dentist. We hope to earn your trust for years to come and welcome you to the Horizon Dental Family.

If you are in pain we always try and see you the same day. If that is not possible, we work to get you in for the next available appointment. We intentionally leave a few openings in our schedule for these types of situations. You can never predict a toothache or broken tooth and we know how hard it is to manage tooth pain.

One of the most common questions that patients ask is about payment options. At Horizon Dental Group we provide resources that make your treatment plan affordable. We have several financing options we can refer you to. We will gladly discuss these with you at your appointment. We also accept all major credit cards, checks and cash.



We are in-network with the listed dental insurance providers. Each office has slightly different variations so we encourage you to give us a call if you don’t see your dental insurance provider listed here.

  • Dr. Costes and his team are amazing. They work with you and let you understand what is going on. I do not have dental insurance, but they offered a discount plan called Ambassador, and I now can afford all the dental treatment I need! The staff is very compassionate and personable! I'm not going anywhere else, this will always be my dental office!

  • I recently had some dental work done at Horizon Dental in Chino. The Horizon team removed my stress with their professionalism and compassion. My appointment started on schedule and the after care recommendations from Darla were much appreciated. Thanks Horizon!!!

  • Dr. Reed is so amazing! I had my teeth cleaned and looked at yesterday, they were very thorough but did not try to "sell" me into treatment that I didn't need. The front office staff was so nice and happy to help with my questions. I would recommend this office to all of my friends and family members!

  • The staff are always superb from start to finish. From the moment I walk in the door until checkout I'm made to feel welcome and part of the "family". My hygienist Kristi was very professional and expressed great care with all of my concerns. I suggest Horizon Dental to anybody looking for new dental care or new to the area.

  • I have been seeing Dr. Costes at the Horizon Dental group since I moved into the area.  He and his team are fantastic.  They made me feel comfortable and at home. They took time to answer my questions and concerns.  I would highly recommend the Horizon Dental group if you need a dentist who is friendly and kind.

  • Great dental office. Everyone was incredibly helpful and explained everything so well. I love that the staff and Doctors volunteer to help people who can't afford dental care. The office is clean and I would recommend it to anyone and everyone. It's worth the drive.

  • Not what you would expect from a small town dental office.  I drive all the way up from Phoenix to see Dr. Costes.  He and the staff are THAT GOOD!  Super clean facility and I am always greeted with smiles and friendly faces.  With all my choices in the valley, I still choose to make the trek up to Chino Valley!

  • Dr Costes was great and replaced my bridge and fixed a loose filling. Fast and painless everyone in his office was friendly and I appreciate how attentive they were and hope I don't need to go back for more than a cleaning but I wouldn't go anywhere else if I need to get work done
