Erik Chestnut, DDS | Mainstreet Dental | Dentist in Parker, CO

Trust, honesty and open communication is the foundation of my dental practice. As the proud owner of Mainstreet Dental, I want to personally thank every patient for entrusting me with your care and your family’s dental needs. I believe in the power of a beautiful, healthy smile. Not only do I hope to make a difference in your life, but I also hope to impact your dental and overall health in a positive way

I serve every one of my patients the way I’d treat members of my own family

While my approach to dentistry is conservative, I am committed to staying current with continuing education and exploring new dental techniques that I believe yield the best outcome. As your dentist, I always present you with individual treatment plan options based on your needs and wants. Not only do I genuinely listen to your concerns, but I also encourage open conversations, education, and building a life-long relationship with you.

I am a Colorado Native

As a native Coloradoan, I chose to remain close to home for my undergraduate degree and my dental degree. I love Colorado and am thrilled to practice dentistry in Parker. I look forward to seeing returning patients as well as new patients, and I promise to provide you with an excellent, uncompromised level of care.

My Philosophy

“The entire Mainstreet Dental team is passionate about providing exceptional care to patients of all ages. Our warm and welcoming environment reinforces our genuine concern. Listening and educating patients on the connection between oral health and whole body health is our priority. WE maintain a no-pressure approach to dentistry by administering evidence-based dentistry and providing procedures that deliver the greatest benefit.

I broke my Front tooth cap right off. My reg. Dentist was closed. I called Main Street Dental. They fit me in, and fixed my tooth. The Dentist and Staff were so very nice and caring, when I was in a panic. Thank you so much!

Dr. Chestnut has been great! I saw another dentist who did a number on a filling I needed and he repaired the damage and has such a great attitude. You can really tell he takes pride in his work and his business. Definitely recommend this dentist!

Dr. Chestnut, his hygienists, and front staff were the best dental team I’ve ever been to. And I’ve been going to dentists for 50+ years. Both he and his hygienist were very thorough, efficient and some of the most pleasant people to be around in any setting. I love this place and they will have a patient for life in me. I would highly recommend Mainstreet Dental.

Dr. Chestnut and his staff at Mainstreet Dental Center were all fantastic! They worked together to make my visit a very positive and productive one. This check up was the most pleasant dental visit I’ve experienced in quite some time. I love the way they were able to create a professional yet casual environment for me as their patient. The charges for my check up were very reasonable. I would and have recommended this dentist to everyone.Thank you Mainstreet Dental Center for making my dentist appointment a positive and pleasant one!
