Concord's Friendliest Dentist

Welcome to the Concord dental office of Drs. Ray Orzechowski and Shannon Arndt, DMD!

Our mission is to provide quality preventative and restorative dentistry to our patients of the greater Concord area in a comfortable, compassionate environment. Using education and the latest technology, we strive to help our patients achieve their optimum oral and overall health for a lifetime. Our goal as dental professionals is to provide all patients with quality services in a warm, caring environment. We focus on the unique needs of every individual, and work hard to design a comprehensive treatment plan that best serves our clients. With a combined 50 years of experience serving the Concord area, we are well-equipped to deliver prime professional care to you and your family.
Preventative Care
Although dental decay and periodontal disease are some of the most common conditions in both adults and children, it is also completely avoidable with preventative care. As long as you take proper care of your teeth by brushing, flossing and using recommended rinses, you can prevent bacteria from causing damage to your teeth.
Cosmetic Dentistry
There are many reasons why you may not be completely satisfied with the appearance of your smile. Stains from coffee, tea, and other foods may have caused your teeth to become darker. Normal wear and tear can also cause your teeth to chip and fracture. There are multiple ways that Dr. Orzechowski and Dr. Arndt  can help improve the esthetics of your smile.
Dental Implants & Dentures
Any tooth replacement option is designed  to restore your ability to eat, speak clearly and smile. Dental implants are modeled after real teeth, and are usually the best treatment option for replacing missing teeth. We also fabricate complete and partial dentures
Endodontics, or root canal treatment, is necessary when the nerve cells inside a tooth break down because of decay or trauma. Often the patient experiences significant pain as a result of the nerve dying, but not always. Dental x-rays are usually needed in order to allow Dr. Orzechowski and Dr. Arndt  to make a clear diagnosis of the problem.

Always friendly and professional

I have been a patient there for over a decade and would highly recommend the practice to anyone. All members of the practice are friendly and seem truly happy to be there. Both doctors are great. I’ve had to go in for dental work twice recently and both experiences were as pleasant as dental work could be.

My kids both really love your office. Everyone is incredibly kind, professional and personal. We love the small, family office feel. My daughter used to be anxious about visiting the dentist. Last night she asked to write a thank-you note because she had such a great time at her dental visit! Thank you.


Professional and friendly

I had a really bad experience with a prior dentist and didn’t want to go back to another dentist for fear of what the prior dentist did to my teeth. I have to say I LOVE this dentist and all the staff here. My fear is gone and I enjoy going to the dentist now. I highly recommend this office!
