Open-mouthed sleep with protruding teeth may be caused by adenoid hypertrophy, rhinitis, dental dysplasia and other factors.
1. Enlarged adenoids: usually occurring in children under 10 years old, when the condition is serious, it will lead to abnormal maxillofacial development or cause peripheral tissue inflammation, which will cause open-mouth breathing, protruding teeth, and so on.
2. Rhinitis: for example, acute rhinitis, chronic rhinitis, allergic rhinitis, etc. When the condition is serious, it leads to blockage of the nose, which prevents normal breathing and may lead to open-mouth breathing, and the teeth will protrude after a long time.
3. Dental dysplasia: for example, congenital buck teeth, paronychia, etc. When the teeth are not well developed, they will be protruding, and the mouth can not be closed properly, which will lead to open-mouth breathing.
If you find that your child sleeps with open mouth breathing, it is recommended to consult a doctor in time, and through relevant examinations to understand the cause of the disease, and then targeted treatment, so as not to affect the appearance.
