4 Easy Steps to a Restful Night’s Sleep

Step 1

Take The Sleep Apnea Risk Quiz

Click on the button below to complete a short online quiz to find out if you might be at risk for sleep apnea. We use common factors to understand whether you are at risk for sleep apnea and look forward to helping you find better sleep!

Step 2

Request A FREE Screening

During this screening, we will have a conversation, provide an evaluation, and discuss your options with you. There is no cost, no pressure, and no obligation, just a great opportunity to get to know our team!

Step 3

Take An At-Home Sleep Test

If you do not have a current sleep study and decide to move forward with treatment, the next step is to be tested for sleep apnea in the comfort of your own bed.

Meet the Doctor

Thomas R Froning, DDS, D.ABDSM

Dr. Froning

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 Littleton 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 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.
