Dear Valued Patients,

After several weeks of sheltering in place, Governor Abbott has announced the much-anticipated plan to safely reopen Texas.  That plan includes the reopening of Texas’ dental practices on May 1, 2020.  We are pleased to resume some normalcy and starting to schedule all endodontic procedures.   While we have been seeing patients with urgent/emergent issues throughout this pandemic, a return to regular scheduling is a welcome progression.

Our decision to reopen was not made without great consideration regarding what it will take to keep our patients and team members safe and healthy. We are implementing strict guidelines regarding PPE and workplace requirements already in place. Specifically, we will be following our organizations guidelines and criteria.  Those guidelines and criteria include but are not limited to:

  • All patients and their escorts will be asked COVID related questions, if any answers are affirmative, they will be asked to defer any non-emergency procedures.

  • All staff, doctors, patients and their escorts will have their temperature checked upon arrival and if it is greater than 100.4 they will be asked to see their medical doctor, rescheduling with us once they are medically clear.

  • When possible, patients will be asked to attend appointments alone.  When an escort is needed (mobility issues, minor, etc.) the escort will be asked to wait in their vehicle or in our foyer/hallway which has chairs.

  • Recommendations for PPE will be complied with.

  • For the foreseeable future we will be staggering patient visits in order to reduce patient to patient interaction.  This necessitates significant scheduling changes so please be patient with us.

We mourn the loss of life, the increased stress and the impact on our personal freedoms that this pandemic has thrust upon us.  However, we have tried to embrace some positives: a chance to unplug, recharge a bit and reconnect with family. 

As we prepare to reopen, I want you to know that we have missed our patients and working with our referring offices and look forward to reconnecting soon.

We believe that these present challenges and difficulties have the potential to make us all a bit better.  Let us look forward to that “better place”.

Our Mission is simple: to provide you with the finest endodontic treatment available anywhere.

We strive for clinical, administrative, and technological excellence in every facet of our practice. It comes from years of experience in the profession and through the use of the latest advances in endodontic technology. We take great pride in being a state of the art endodontic practice and are committed to caring for you, our patients, as we would our own family. 

Practice Profile

Dr. Harris proudly offers quality dentistry specializing in Microscopic Conventional and Surgical Endodontics.   

Endodontics is a microscopic science.  In our practice, diagnostic and therapeutic treatments are performed using the Dental Operating Microsope to provide superior visualization inside the tooth.  This technology increases our ability to provide more complete and conservative dental treatment.   At magnifications of more than 20x and with optimal lighting, we are better able to see extra canal systems, unique anatomical complexities, and to identify fractures.

Our office utilizes advanced digital imaging which reduces radiation exposure during dental x-rays.  Because these images are digitized, the Endodontist uses computer software to amplify and manipulate images for better diagnostic purposes. We are also very proud to be utilizing 3-D volumetric imaging, also known as Cone Beam Computed Tomography (CBCT).  This new technology allows complete 3D visualization of the teeth and supporting structures with ultra low radiation exposure. This breakthrough technology provides unprecedented radiographic views of the teeth and supporting structures. When appropriate, this technology can be an indispensable tool for proper diagnosis and treatment planning. This device also minimizes radiation exposure by having a very small area of focus to allow detailed visualization of the area of interest, without unnecessary exposure to surrounding tissues.

Dr. Gary Z Harris has practiced Endodontics in Sherman since 2001.  Before moving to Sherman, he practiced Endodontics in Plano for over 20 years.  Dr. Harris graduated from Baylor College of Dentistry in 1979 and received his Certificate in Endodontics from LSU School of Dentistry in 1981. He has been involved in local and international organized dentistry and endodontics throughout his career.  

Dr. Harris and his team, Jackie, Naomi, Larissa, Brandi, and Diana are well known in the Texoma region,  North Texas and Southern Oklahoma.

Dr. Harris is wonderful! He solved my problem and my tooth pain is gone! He’s a wonderful Endodontist  and I would highly recommend him.

Anyone dreading a root canal should see Dr. Harris; he’s the best in the business!  The doctor and his team make visiting a dental office very pleasant.  You know from the beginning exactly what the procedure will be and the time and cost expected.  My wife and I have had a total of four root canals from Dr. Harris.  It may sound impossible, but the procedure is virtually painless.  He is a caring and professional man.  His entire staff is efficient, courteous and friendly.
