for the Treatment of Obstructive Sleep Apnea

At Long Island Dental Sleep Medicine, we are proud of our continuing commitment to the field of dental sleep medicine. Dr Seltzer and Dr. Rein remain dedicated to education and research, and are both an active part of a distinguished group of only a select few Diplomates of the Academy of Dental Sleep Medicine. While maintaining their practice, they also serve as consultants to several New York area hospital-based sleep centers and work closely with other local private sleep centers.

Normal breathing during sleep vs. Obstructive Sleep Apnea

What is Sleep Apnea?

Sleep apnea is when breathing stops temporarily as a person sleeps. More than 12 million Americans are affected by sleep apnea. There are three types of sleep apnea:
  • Obstructive sleep apnea is the most common type. It is caused by the airway being blocked, usually by soft tissue in the rear of the throat, causing the throat to collapse and close during sleep.
  • Central sleep apnea is when the muscles that control breathing fail to receive the proper signals from the brain.
  • Mixed sleep apnea is a combination of both obstructive and central sleep apnea.

“Dear Dr. Rein, this has worked better than any surgery he had. He can sleep on his back again and breathe. Before this, he stopped breathing on his back.”

“Dear Dr. Seltzer, I wish to express my appreciation for the dental device which has dramatically diminished my problem with sleep apnea. I woke with vision and vigor and my quality of life has substantially improved. I unconditionally endorse this device and the dentist who treated me.”
