Bio:
Crystal Butler, BSDH, OMT Licensed Dental Hygienist | Orofacial Myofunctional Therapist | Founder, Key Myofunctional Therapy, LLC
I’m a licensed dental hygienist specializing in Orofacial Myofunctional Therapy, with over a decade of experience in oral health. My work focuses on the critical connection between oral function and whole-body wellness.
Through Key Myofunctional Therapy, LLC, I provide personalized care for issues such as mouth breathing, tongue thrust, tongue-tie, TMJ muscle-related dysfunction, orthodontic relapse, muscle-related sleep-disordered breathing, and hypermobility-related instability. My approach is airway-focused, helping patients address the root causes of symptoms that interfere with breathing, sleep, posture, and oral function.
My academic foundation includes dental hygiene education and advanced training through the Academy of Orofacial Myofunctional Therapy. I am currently pursuing my Master of Health Sciences while continuing to collaborate with airway-focused practitioners and contribute to advancing the evidence base through scientific research.

I’m passionate about educating patients and partnering with dental, medical, and allied health professionals to create lasting, functional outcomes. Each therapy plan reflects my commitment to combining evidence-based methods with compassionate care to restore optimal function and vitality.
If you’re ready to explore how myofunctional therapy can help you or your child, I invite you to schedule a free consultation—I’d be honored to walk alongside your healing journey.
