What is a periodontist?

A periodontist is a dental specialist who focuses on the gums, bone, and structures that support your teeth. After completing dental school, periodontists complete an additional three years of specialty training. They treat gum disease at all stages, place dental implants, and perform surgical procedures like gum grafting and osseous surgery.

How long does gum graft recovery take?

Most patients recover from gum graft surgery in one to two weeks. The first two to three days are the most uncomfortable, and most people return to normal activity within a week. Full tissue maturation takes two to three months. The Pinhole Surgical Technique, which we offer, typically has a faster recovery than traditional grafting.

ABOUT US

Welcome to Our Practice

Our Story

Colorado Gum Care was founded in 1986 by Dr. Mark A. Wheeler, a board-certified periodontist with a vision for bringing specialist-level gum and implant care to the Broomfield community. Over the decades, that vision has grown into a multi-location practice with five highly decorated periodontists serving patients throughout the Denver metro area.

Today, Colorado Gum Care operates two convenient offices — in Broomfield and Northglenn — and is consistently recognized as one of Colorado’s premier periodontal practices. Every physician on our team holds board certification from the American Board of Periodontology, an achievement that fewer than half of practicing periodontists earn.

In 2026, 5280 Magazine once again named our team among Colorado’s Top Periodontists — a recognition our practice has earned year after year.

      Trustindex verifies that the original source of the review is Google. This is my second gum graft that I had to get and this has been a better experience for me.  They made the surgery pain free as they sedated me this time which I did not get that option last time.  Dr. Rademacher is an extremely caring, knowledgeable, dedicated and patient! When I first met him at my consultation I left there knowing i was in the right hands with my care!! He did not fail to make that a true statement!! I also received a phone call later that day after my surgery from him to check on me! Dr. Rademacher definitely needs to be recognized!! Thank you again for taking such good care of me!!

     Trustindex verifies that the original source of the review is Google. Dr Borg and his assistant were fabulous! My anxiety going in was far worse than the procedure itself.  I hope I dont need this type of care again....but if I do.....I would definitely go back to Dr Borg.  Thank you!

     Trustindex verifies that the original source of the review is Google. Medical staff were caring and competent. I received calls from the dentist, performing 2 grafts, and the anesthesiologist the day before. They were available for questions or concerns. Follow up care was clear.

     Trustindex verifies that the original source of the review is Google. Dr. “TyBorg” is about the best dentist I’ve ever seen. He’s now doing my second implant with him. The whole experience is ver comfortable. I experienced no pain and did not even see any blood ever. I was very well cared for. He’s very good at answering questions and explaining things too, and he’s always asking if you need anything else. The whole team is like that.
