Do you have a narrow upper jaw, protruding teeth, crowded teeth, or a recessed lower jaw? Many people think these issues are genetic and can't be fixed. However, a significant cause might be incorrect breathing habits from childhood, specifically mouth breathing.
This article will help you understand the difference between correct nasal breathing and mouth breathing, which can negatively affect your facial structure in the long term.
Nose Breathing vs. Mouth Breathing: The Differences That Affect Your Health and Facial Structure
Normally, when we breathe through our nose, our tongue rests in the correct position on the roof of the mouth. This acts as a "natural palate expander," helping the upper jaw grow forward and to the sides properly.
However, when we breathe through our mouth, the tongue drops to the bottom to keep the airway open. The absence of the tongue's pressure on the palate leads to changes in facial structure, as follows:
1. Changes to the Jaws and Palate
Narrow and Elongated Upper Jaw: Without the pressure from the tongue, the upper jaw is pushed inward by the cheeks. This causes the maxilla to grow in a narrow and elongated manner instead of expanding to the sides.
High-Arched Palate: The narrowing of the upper jaw causes the palate to become abnormally high and arched. This, in turn, reduces the space inside the nasal cavity, making it even more difficult to breathe through the nose.
Recessed Jaw (Recessed Mandible): When the upper jaw doesn't fully develop forward, the lower jaw is unable to grow forward. This results in a chin that looks short or receded.
2. Effects on Teeth Alignment
Protruding and Crowded Teeth: When the upper jaw is narrow, there isn't enough space for the teeth. This causes the front teeth to protrude (overjet) or become crowded, problems that often require orthodontic treatment.
Malocclusion (Abnormal Bite): The changes in both the upper and lower jaws prevent the teeth from fitting together properly. This leads to chewing problems and can even affect the temporomandibular joint (TMJ).
3. Altered Facial Features (Adenoid Face)
When this habit persists during childhood, it can lead to a specific set of facial features known as "Mouth Breathing Face" or “Adenoid Face”, which include:
A long and narrow face
A short and upturned upper lip
Slightly parted lips at all times
Tired-looking eyes or dark circles under the eyes
Narrow nostrils
How Can This Be Corrected?
Correcting problems caused by mouth breathing should begin with treating the root cause. This involves consulting an ENT (Ear, Nose, and Throat) specialist to address any nasal obstructions, such as enlarged adenoids or tonsils.
Afterward, an orthodontist can help correct the abnormal jaw and dental structure. This may involve using a palatal expander to widen the upper jaw, creating more space and helping to restore proper nasal breathing.
Mouth breathing doesn't just harm your overall health; it can also visibly alter your facial appearance and structure. Observing and correcting this habit early, especially in children, is a key step in preventing these issues and building a confident smile for the future.
If you or your child has any of the problems mentioned above such as mouth breathing, snoring, allergies, protruding teeth, or crowded teeth or if you would like a facial and bite check-up for long-term prevention, you can consult with our team of specialized orthodontists at Songkhunmor Judfun Dental Clinic (SKM Dental Clinic).
