When one cavity is significantly smaller than the opposite, it is often difficult to breathe through your nose. This symptom could also be most noticeable in the dark when you’re trying to sleep, or it can interfere with your breathing during exercise or sports activities.
You may have to compensate with persistent mouth breathing, which dries and irritates your oral mucosa and may eventually damage your teeth. Saliva may be a protectant that helps wash away debris that attracts decay-causing bacteria.
An abnormality makes it harder for air to maneuver through your nasal passages, which dries the moist membranes lining your nose and causes you to be more susceptible to nosebleeds.
