The main reason for dry mouth at night may be mouth breathing instead of nasal breathing. Patients should avoid mouth breathing during daily activities, try not to sleep with their mouth open, and keep a glass of water nearby to drink from when they wake up feeling dry-mouthed, thus relieving the discomfort. In addition, oral conditions such as improper bite or misaligned teeth may lead to mouth breathing during sleep, resulting in dry mouth and throat.
