Mark L Harris DMD PC
Dr. Harris and April are the very best! Attentive, knowledgeable, courteous, and professional- they are the best care I've had in 50 years of visiting the dentist. I received excellent care and a compassionate response to all my dental needs. Dr. Harris, Colleen, and the whole team are great and go out of their way to make sure I feel welcome and at ease.

At the practice of Dr. Mark Harris, we combine traditional service values with forward-thinking dental treatments. Our La Grande, Oregon dental office features the latest technology, including dental lasers, and Dr. Harris stays abreast of modern dental solutions. We proudly offer an array of family dentistry and cosmetic dentistry services designed for patients of all ages.
Services
Designed to make you feel at home, our office features advanced technology, and our team members take pride in knowing each of our patients personally. We'll know your name, ask about your family, and even better - we genuinely care. To maximize your family's safety, we use digital X-rays that expose patients to about 80 to 90 percent less radiation than traditional radiographs.
As a general dentist with over 26 years of experience, Dr. Harris offers a wide range of dental services. From preventive care for the whole family to cosmetic dentistry and replacement teeth, our practice can deliver the friendly, state-of-the-art dental care you deserve. We proudly use advanced technology, and Dr. Harris considers comfort, esthetics, and longevity top priorities for every patient we see.
A Portland native, Dr. Harris attended the University of Oregon for his undergraduate studies. In 1993, he graduated from the Oregon Health Sciences University with his DMD. Following graduation, Dr. Harris moved home to La Grande and began as an associate to Dr. Lynn Harris. He opened his private practice in 2000 where he provides comprehensive general dentistry and cosmetic dentistry, as well as sleep apnea therapy.
Cavities may seem like a part of life, but did you know that they can actually be prevented? As a family dentist, Dr. Harris helps patients of all ages prevent unnecessary dental trauma. With regular checkups, exams, and proactive preventive therapies, we can help you preserve your natural smile for a lifetime.
There's never been such an exciting time for dentistry! Over the last few years, the demand for high-quality, conservative dental treatments has given us amazing results. Now we can build a brand new smile using the more natural-looking and durable materials than ever before - often in just a few short visits.

Absolutely the worst office staff I've ever dealt with. Dentist can't be much better if he hired them. No wonder the parking lot is always empty.

I am such a chicken when it comes to dental work, the staff and doctor were amazing. Made me feel very comfortable, we’re very positive and honest. I will be going back and very happy I chose them.

We have been going to Dr Harris for 20 years and have always been treated with care, professionalism and courtesy. The staff is friendly and Dr Harris is an excellent dentist. He is very attentive and friendly. We have since added three children to the mix who have been his patients since they were babies. We moved away from La Grande 17 years ago, but continue to make the trip back every 6 months because we did not want to lose Dr Harris as our dentist.

Dr. Harris and his staff are always great! Dena at reception is always so friendly and Hayden in the back is super personable. Dr. Harris has bent over backwards to help me with getting my smile back and I’d highly recommend him to anyone! They really take the time to make sure you understand what’s going on with your car whether it be billing, scheduling, or dental related.

Dr. Harris and his staff are the best! Due to genetics, accidents, and lyme disease, I have had a life-time of challenging dental issues. Dr Harris has been my dentist for the last 18 years and has always gone above the call of duty with his expertise, generosity, and perseverance to get me to the best situation possible. I am so grateful to him and his staff for hanging in there with me!

After waiting eight months for my appointment to fix a lost filling, that's right eight, there was a glitch in their insurance system saying I didn't have insurance, when I do. But rather than double check with me or the insurance company they just cancelled my appointment. Not the only dentist in town.

I have recommended Harris Dentistry to several friends and family. I can't say enough good things about this practice. Everyone is friendly and helpful. In addition to excellent dental care, I got cosmetic overlays on my front teeth and they are beautiful. Far less costly than veneers. He is also very good with injections and love that he hums all the time! :)

I've been seeing Dr Harris for over 4 years now and I have never had anything but wonderful things to say about him and his staff. Incredible service! I've never waited longer than 5 minutes to be seen. They are always so friendly and courteous and completely respectful of me and my family's needs and concerns. I HIGHLY recommend Harris Family Dentistry. You will not be disappointed. I never have been.

Best Dentist ever! He knows I have major anxiety and still takes good care of me even though most time I am already crying by the time he walks in!

I've been a patient of Dr. Harris for 5 years. Every encounter has been a pleasant and painless experience. I've been impressed with the professional service and their ability to put you at ease. The staff interacts and works well with each other smoothly with each knowing what to do next. Dr. Harris and his staff have found a few problems and fixed them before they became BIG problems. I highly recommend them to everyone.

Best dentist I've ever been to. He really cares! Messaged me after my appointment to make sure I was ok. Not many do that.

Was referred here by by ODS dental hygienist school due to some cavities. The office is spotless with all the latest equipment. Nitrous is free (yeaahh!!) and you can watch TV while the dentist is working. The assistants were flawless and Dr. Harris was very personable and extremely fast. Very low stress dental visit.
