  • Some people may have red and inflamed gums because of drying out the tissues in their mouth. Despite you remoistening it during the day and having excellent oral health, you may find that you have bleeding gums or cavities from sleeping with an open mouth.
  • Another sign would be experienced in your throat. If it feels dry or itchy upon waking up, or you feel a burning sensation.
  • A dried mouth from being left open for so long can also lead to bad breath, even when they keep good oral hygiene.

Your sleeping position can worsen your breathing, which results in you leaving your mouth open without knowing it. Make sure that you are always sleeping with your head elected above your body. Use a right pillow that will keep your head elevated, but avoid it from being too high up that it will leave neck pain.

As for your position, it's best to avoid sleeping on either your back or stomach. Opt to sleep by your side, which is good for back support while lessening the chances of you breathing through your mouth.

Changing Your Bedroom and Lifestyle

Obesity is another reason as to why you have breathing problems, so I recommend you to change your habits and start eating healthily, incorporating foods that help with sleep and weight loss, if needed. Exercise will help lessen your breathing problems and have you rest with your mouth closed as well.

Your bedroom should be free from allergens or anything that can give you colds or sicknesses that affect your breathing. Avoid sleeping with your pet and remove any plants from the bedroom, as they use up more oxygen and will have you fight for it. Remove carpets and rugs, replace your pillows and blankets that are too warm. 

If the symptoms of an open mouth while sleeping persists, then you may need to see your doctor, as it may be an underlying sleeping disorder or a problem with your medication. Or, it may require therapy and other forms of medication to cure yourself of any condition you may have that causes you to sleep with your mouth open.
