Welcome

Proudly Serving Sherman Since 1994

We often find ourselves treating multiple generations of the same family, and the reason that Sherman has trusted us for decades is simple—they know they can rely on us to deliver honest, high-quality, and personalized dental care at every single visit.

A Personal Approach
to Dentistry

The big thing that makes our dentists unique is that they spend a lot of time listening to their dental patients instead of just telling them what they need. By truly understanding someone beyond their teeth, they can tailor their approach to make it more comfortable, effective, and efficient. Plus, this allows a strong, trusting relationship to blossom that makes follow-up appointments much easier.

Kind Words Straight from Our Dental Patients

We recently made the decision to switch dentists, and the staff and doctors at Grant E - Mark A Smith DDS were great. The office staff are very friendly and accommodating. If you are a new patient waiting for an appointment, they are diligent about keeping a list and calling you if there is a cancellation and you can be worked in. The hygienists and doctors were personable, professional, and friendly, too. I'd recommend this practice to my friends and family.”

Stephanie C., Sherman, TX

Dr Grant Smiths office got me in with less than a days notice due to a broken filling. I was quoted a price, treated so respectfully and was in and out in an hour. Seriously the most pain free dental experience ever! Best dentist I’ve ever seen in the Sherman or Denison area BY FAR! STAFF WAS SO KIND.”

Buffy H., Denison, TX

Doctors Grant and Mark are always personable and knowledgeable. I love that they are conservative in their treatments. Some dentists will try to fill every tooth in your mouth, but not here. I've been a patient for about 15 years. When I moved to McKinney I struggled to find a conservative treatment dentist, so I make the drive back to Sherman for my cleanings. Everyone here is easy to talk to, from the front desk employees, the hygienists and the dentists.”
