We strive to not just uplift our individual patients in your area, but the community as a whole by providing excellent, personalized dentistry in Arlington Heights that is always delivered with a healthy dose of kindness. Simply put, we’re here to serve you however we can – from routine checkups to sudden emergency dentistry.
Our dental practice near you was started by Dr. Ernie’s father over 55 years ago, and today, we often find ourselves taking care of four generations of the same family! From essential preventive care and dental implants to cosmetic dentistry, we’ve earned people’s trust year after year and decade after decade because we love what we do and who we serve (and it shows).
CaringWe treat our patients the same way we would our family and best friends. You’re a person before you’re a patient, and we never forget this.
PositiveGoing to the dentist can be stressful for some, but we keep things light and upbeat even when it’s not easy to do so.
Team PlayersYou’ll never talk to a team member who doesn’t know who you are. Together, we’re able to consistently deliver exceptional care and service.
ProfessionalWe consider all of the details so you don’t have to. From our appearance to our communication to your treatment, our dedication to quality will be obvious.
Sure, Dr. Ernie, Dr. Jay and Dr. Nicole can enhance your smile with veneers, straighten your teeth with Invisalign, or get you out of pain with TMJ treatment. However, this is not their primary goal—it’s just where they begin. Their top priority is to become an advocate you and your family can rely on for years to come. Whether you have major issues or just want routine care for you and your loved ones, you can count on them to answer all your questions and serve as your guide toward the bright, beautiful, and healthy teeth you deserve.

“I decently chipped my two front teeth last week and though the office was closed, Dr. DeHart responded fast and was able to fix my teeth within hours. Everything was done very gently and all of my questions were answered thoroughly, which meant a lot to me especially in my panicked and injured state. My teeth look amazing and I have never had anything but amazing experiences here. Thank you again!!”
“This was a professional and expert dentist experience that had had a profound impact on my life. I was treated with upmost patience, kindness, and professionalism. I was given time and care that I would’ve otherwise never been able to afford. This was much needed, but not required help to a veteran. It absolutely has changed my physical health and improved my life for the better. I’m beyond grateful for the Dr. J, his partner and his amazing staff.”
