Sleep apnea can be treated by utilizing dental devices. Most of these devices are acrylic and fit inside your mouth like an athletic mouth guard. Other devices such as the mandibular repositioning device and the tongue retaining device are worn over the head and chin, which helps adjust the position of your jaw and tongue so that your airways remain open. When using these dental devices, it's important to consult a dentist who specializes in sleep apnea and have the equipment properly fitted. There are other things you can do every day to minimize sleep apnea, including avoiding smoking, alcohol, heavy meals, caffeine, keeping regular sleeping hours and sleeping on your side.
