Thomas R. Froning, DDS, D.ABDSM
- Denver’s Qualified Sleep Dentist
- Treating Sleep Disordered Breathing
After helping hundreds of his dental patients overcome sleep-related breathing disorders, Dr. Froning decided to focus exclusively on sleep and established Sleep Center of Colorado in 2019. He earned his Qualified Dentist designation from the American Academy of Dental Sleep Medicine, and in 2020 became a Diplomate of the American Board of Dental Sleep Medicine.
Dr. Froning is a strong advocate of alternatives to CPAP and treating OSA through Oral Appliance therapy because of his own personal experience, “As an extremely healthy person, I was shocked when I had a heart attack 8 years ago so naturally I began researching and learned that sleep apnea is a big contributor to cardiac health. I also discovered that oral appliance therapy is a recommended treatment for cardiac care. So I started wearing the appliance and immediately felt stronger and had more energy. At that moment, I knew I wanted to treat snoring and sleep apnea so that I could improve people's overall well-being and in some cases, even save people’s lives.”
He and his team are committed to providing the highest level of patient care and commit to hundreds of hours of continuing education every year in order to continue exceeding national standards for successful sleep apnea and snoring treatment with CPAP alternatives.
Dr. Froning lives in Littleton and enjoys climbing Colorado’s Fourteeners, skiing, fishing, and traveling, as well as spending time with his family.
