Breathing through the mouth rather than the nose dries the oral tissues and reduces the protective effect of saliva. Over time this can contribute to gum inflammation and an increased risk of decay.
In children, habitual mouth breathing is also associated with changes in facial and dental development, which is why it is worth raising at a routine check-up.
Assessment looks at nasal airway, tonsil and adenoid size, tongue posture and sleep quality, and may involve referral to an ear, nose and throat specialist.
