Peter T. Harnois, DDS

Dr. Harnois graduated from University of Illinois College of Dentistry with Honors in 1982. He was Class President for 3 years and received numerous awards for educational and clinical excellence. Dr. Harnois has been practicing Dentistry in Hinsdale for over 30 years.

His philosophy is to provide the most gentle and minimally invasive cosmetic and metal-free dental treatments with natural results.

“Having grown up in Hinsdale my patients feel like family to me. We bring our A game every day and from the moment you enter our office until you leave we focus our full attention on you as an individual so you get the best customized care that fits your needs, wants and desires.

Dr. Harnois lectures internationally to properly educate his fellow dentists around the country on emerging technologies in dentistry that he utilizes in his own practice. He is the President of the Illinois American Academy of Facial Esthetics and trains dentists on injection techniques.

Dental Tips from Dr. Harnois: Most of my patients come in with fear and anxiety about their upcoming dental appointment. We use the NuCalm system to naturally relaxed them and eliminate their fears.

Worn, chipped, gapped, crooked, stained teeth are some of the most common patients concerns. Minimally invasive porcelain veneers that do not involve shots, temporaries or removal of painful tooth structure are a great choice to treat these conditions and achieve a permanent straight, stain-free smile.

We offer a full range of biocompatible, metal-free dentistry to remove and restore old metal fillings and crowns.

Throughout his education, he received several awards for his commitment and proficiency in the fields of endodontics, general dentistry and cosmetic dentistry.

His philosophy is that patients should expect an unwavering effort from their doctors to provide uncompromising care, and it is the provider’s responsibility to deliver such treatment with a commitment to excellence.

“I find great value in working together with patients to have them become more involved in their treatment. Not only does this allow them to become aware of their dental condition, but it gives them the opportunity to understand how we can work as a team to attain the highest level of well-being possible.”

Dental Tips From Dr. Jon: Research has continued to show a link between oral health and overall health as many diseases and disorders experienced by the body can manifest into dental problems and vise versa. In particular, patients with sleep apnea demonstrate several unique signs and symptoms that can be seen in your mouth by your Dentist. Regular dental check-ups are important as it can help to promote a healthier mouth, and therefore a healthier life.
