It can also cause migraines, pain in the jaw, and make adults more sensitive about their appearances.
Deviated Nasal Septum

Facial deformations are possible due to mouth breathing, especially in children whose bones are still developing. If a child breathes through the mouth excessively during the formative years, an ill-positioned or uneven facial and jaw structure can occur.
Good oral health involves more than just brushing and flossing your teeth every day. If you breathe through your mouth at night, the jaw is forced into an unnatural position for long periods of time. This can lead to teeth grinding and the development of an overbite or an underbite. Gum disease and tooth decay are also more likely with mouth breathing.

Air that is inhaled through the mouth isn't as warm or moist as air that comes in through the nose. This can make the airway more irritated and breathing more difficult.
Worsened Sleep Apnea
A condition of sleep apnea is also likely to worsen if you breathe through your mouth at night. The position of the jaw during mouth breathing makes it more difficult to sleep. Also, chronic mouth breathers often need larger continuous positive airway pressure (CPAP) masks for their sleep apnea. Snoring is also worsened with mouth breathing, and you may feel more fatigued in the morning because mouth breathing doesn't let as much oxygen into the lungs.
How to stop sleeping with your mouth open
Once you realize at you are sleeping with your mouth open on a regular basis, it's a good idea to take action right away to correct the behavior. During the daytime, make a conscious and intentional effort to breathe through your nose while awake. This will help train your body to breathe this way while you are asleep as well. To help you remember to breathe through the nose, consider placing Post-It notes around your desk or house. Or perhaps set a reminder on your phone or smartwatch for the same effect.
Also, practice good posture throughout the day so that your head does not extend forward unnaturally. This is a common and potentially harmful body position among mouth breathers.
When it's time to sleep, elevate your head to clear the passages for unrestricted air flow and prevent intestinal fluids from going up the throat. You can use a reflux board or multiple pillows to achieve this position. Avoid sleeping on your back, because this forces you to take larger breaths and breathe through the mouth to get rid of excess air. It's better to sleep on your side or stomach if you're prone to mouth breathing.
It may also be beneficial to invest in a sleeping mouth guard that is made to help keep your mouth shut while sleeping. This is a good solution to try if other remedies haven't been working.

If a blockage of the nasal passages is to blame for mouth breathing, then it may be necessary to take a decongestant, antihistamine, or use nasal spray to increase the air flow through the nose. You should also remove any potential allergens from your bedroom, such dust objects, pet beds, and houseplants. Wash your bedsheets and pillowcases frequently to rid them of dirt and dust that can make nose breathing more difficult.
If there is no defect or illness of the nose that prohibits nose breathing, then you may want to consult a doctor or myofunctional therapist to learn about proper breathing techniques. Some yoga and meditation teachers are also skilled in deep breathing exercises that can help. You can practice breathing in deeply, holding the breath, and exhaling through the nose throughout the day until it feels like second nature.
There's a nose clearing exercise called Buteyko that some people swear by to unblock the nose and take proper breaths. To try it, sit calmly and focus on breathing through your nose for a few minutes.
