Often, with prolonged mouth-breathing due to allergies,
large tonsils or adenoids, nasal obstruction, deviated septum or just
habit, the upper lip will shorten so that it does not cover the teeth.
Because the tissue of the upper lip is muscular, and very flexible,
it is possible to lengthen it to cover and protect the teeth. Dentists
are often concerned about mouth-breathing because it can dry the gums
of the front teeth and can cause swelling and redness.
Large tonsils / adenoids and chronic nasal inflammation
are contributors to mouth-breathing, tongue thrust and poor tongue
posture. The inability to nasal breathe can cause a person to become
a mouth-breather. By resting with the mouth open, the tongue must
assume a low and forward position to allow for a maximum airway. The
upper lip tends to become shorter as the lower lip tends to lengthen
and internal oral tissues become exposed. As the lips and tongue assume
the correct positions, nerve and muscle differences begin to take
place.
Our therapy program begins by re-training the tongue
to assume the correct resting and swallowing position on the roof
on the mouth. This can help to establish a nasal-breathing pattern.
Sometimes patients are referred for an ENT evaluation. Just as importantly,
we teach the facial muscles to support this corrected position. This
is accomplished through an exercise program designed to take about
5 minutes 3 times per day.
