Read a personal note from Dr. Graham


"It seemed so cute at first..."

My oldest nephew appeared to be sleeping so peacefully at night. In fact, he would even snore from time to time, which his parents were convinced was a sign that he was just “sleeping hard.” As a baby, he didn’t nurse well for my sister. As time went on, he had some early speech delays at two years old, and we recognized that during the day he breathed exclusively through his mouth. As a dentist, I knew something was wrong, but I also didn’t have the training from dental school to know what exactly was going on. So, true to form for me, I went searching for answers. I kept asking why!

In my quest for more information, I ended up opening Pandora’s Box. Research related to airway’s central role in overall health and wellness jumped off the page for me. So much of the reading, discussing and learning that I did put into context what I saw in so many patients.

  • Adults living with chronic exhaustion and fatigue.

  • Exasperated moms who did everything in their power to get their baby to nurse successfully, but couldn’t.

  • Lifelong dental issues stemming from limited tongue mobility and dysfunction, undeveloped facial musculature and inadequate space.

If you know anything about me, it’s this:
when something strikes me as important, I go all in.
In my journey as a general dentist, I was consistently seeking more and more knowledge to better understand why my patients were at risk for what I considered avoidable dental care. That led me down what I first believed to be a rabbit hole and have since learned to be a bottomless crater of continuing education. I have an insatiable thirst for understanding “The Why”. The question of why consistently led to disrupted, fragmented sleep, mouth breathing, and mouths that grew too small to accommodate the tongue.  What started as a subtle wondering turned into a full blown commitment to attending as many conferences, lectures, workshops, and collaborative meetings as possible. I have been fortunate enough to listen and learn from many of the world’s leading experts in the field of sleep disordered breathing, growth and development and dental health. I am even more fortunate to now call many of these experts mentors and friends.

As with any new knowledge, once it’s seen, it can’t be unseen. I started to see myself, my family, and my patients in so many of the lectures I attended. I slowly started to apply what I was learning to treatment for my crew. I was endlessly grateful to watch the people I care the most about have positive changes in not only their dental and systemic health, but also their quality of life. This journey continues daily and won’t end until I retire. And even then, if I’m like my retired dentist dad, I’ll keep attending conferences!

And that’s how Untethered started and will continue to grow.
I am endlessly passionate about improving everyday life for people. So much of that starts with the ability to breathe, and to sleep, and to do these basic, unconscious things that have such a huge impact on our entire well being. I firmly believe that commitment and attention to the most basic of human function, nasal breathing and stable sleep, can prevent a multitude of unnecessary medical interventions and compromised quality of life.
