Overview
An oral appliance for sleep is a custom-made device worn at night. It gently holds the lower jaw forward, which helps keep the airway more open during sleep.
It can help with snoring and mild to moderate sleep apnoea, often for people who cannot tolerate a breathing machine. It is one option, not a cure-all, and works best when diagnosis and follow-up involve your doctor.
