A rhinomanometer is a diagnostic tool used to measure a patient’s ability to breath through the nose. Why is this applicable to dentistry you may ask? A patient’s ability or inability to breathe through the nose affects their occlusion or bite. When a patient habitually mouth breathes it will over time create a malocclusion or bad bite. In the younger patient who is still growing it can create skeletal as well as dental issues. It is important for us to know this information in certain cases before a treatment plan is completed. Proper breathing is essential to every individual’s overall good health.
