Mouth Breathing
Mouth breathing means air is passing through the mouth rather than mainly through the nose.
[5]The short answer
Mouth breathing means air is passing through the mouth rather than mainly through the nose. It may be noticed during sleep, exercise, illness, or periods of nasal blockage. A dental or medical assessment is the right next step when it persists, worsens, or comes with other concerning symptoms.

What relief is safe tonight?
Note when mouth breathing occurs and whether it comes with snoring or difficult sleep. Arrange an assessment when it persists, affects sleep, or appears with other breathing concerns.
[7]How is it checked?
A clinician considers the history and examines the nose, mouth, throat, and adenoids when relevant. The pattern helps separate a temporary problem from an obstruction that needs care.
