About Us
SLEEP BETTER COLUMBUSMeet Dr. Levy
Dr. Levy, a lifelong resident of Columbus, Ohio, has practiced dentistry in Central Ohio since 1979. While he began his career with a strong focus on cosmetic and restorative dentistry—including serving as the local “Extreme Makeover” dentist during the television show’s successful run—his professional passion has evolved. For over a decade, he has dedicated his practice exclusively to the treatment of sleep apnea, snoring, TMJ disorders, and chronic headaches.
After extensive post-graduate education, his training led him to the field of TMJ and sleep disorders. Since 2014, his focus has been on Dental Sleep Medicine, helping patients who suffer from obstructive sleep apnea and related conditions but cannot tolerate or prefer not to use CPAP machines.
At Sleep Better Columbus, which Dr. Levy founded in 2015, patients receive custom oral appliance therapy designed to improve breathing during sleep. His slow-paced, one-on-one approach ensures that every patient fully understands their treatment options, time frames, and associated costs before moving forward.
Dr. Levy holds Diplomate status with the Academy of Clinical Sleep Disorder Disciplines, reflecting his commitment to advancing the field of Dental Sleep Medicine. He has lectured both nationally and internationally for the American Academy of Sleep Solutions—presenting multiple times in Moscow and St. Petersburg, Russia.
If you’re suffering from poor sleep, snoring, or have been diagnosed with sleep apnea and are seeking an alternative to CPAP, Dr. Levy’s practice provides personalized, compassionate, and scientifically grounded care. He looks forward to helping you achieve the restorative sleep that all people deserve.

What Our Patients are Saying
Leslie Ord
“Dr. Levy and his staff are focused on assisting their patients. Five years ago I was fitted for a dental device to treat sleep apnea. Over the last three years, I had dental work done and needed a new device. I did not hesitate to return to Dr. Levy and I am experiencing restorative sleep again.“
