Do you often feel as if you could use a nap in the morning AND the afternoon? People with sleep apnea rarely get a good night of rest, leading to routine fatigue during the day. Sleep apnea is an underdiagnosed medical condition that interrupts normal sleep during the night, making you feel drowsy and irritable from the moment you wake up. Fortunately, our dentists offer sleep apnea therapy in Houston, TX, using a simple oral appliance that, when worn consistently during the night, alleviates the breathing problems associated with sleep apnea.
