bimaxillary protrusion

Protruding mouthWhat is...?

The front teeth themselves orSkeletal structureGrows excessively

It refers to a position toward the front.


A protruding mouth or retroclined teeth fall under Class II malocclusion, which also affects the shape of the lips and can negatively affect facial appearance. Class II malocclusion occurs when there is not enough space for the teeth, and it can also occur when the lower jaw is small or set back, as with a retruded chin, or when the upper teeth protrude.
Protruding teeth are usually caused by genetics, but habits such as finger-sucking, tongue thrusting, and mouth breathing can also cause problems over time. In many cases, tooth extraction is needed to create space for orthodontic treatment. The front teeth are then moved into the space left by the extractions, gradually closing it and moving the teeth back.

gummy smile

Gummy smileWhat is...?

When you close your mouth, your lips look protruded,

A lot of your gums show when you smile.


One type of protruding mouth occurs when the front part of the upper jaw grows significantly downward. Excessive gum display is also called a gummy smile, a name that refers to the gums showing too much when you smile. Besides protruding teeth, causes can include excessive growth of the upper jaw, which makes the gums look larger overall, or a long upper jaw area that pushes the teeth downward. Another possible cause, unrelated to the jawbone, is lifting the lip muscles too much when you smile.


Perfect Dental Clinic recommends treatment through a non-surgical orthodontic program that expands the range of treatment options without surgery. Using appliances made to suit each person’s growth characteristics and our expertise, we aim to improve both forward and vertical growth in protruding areas. Treatment can also be done at the same time to make your gums less visible, based on your smile line.

During protruding mouth correction
What is the key point?

If the protrusion is simply due to the angle of the front teeth, the teeth can be moved inward into the space left by tooth extraction, and their angle can be adjusted. However, when a skeletal imbalance is caused by abnormal upper jaw growth, correcting the angle of the front teeth while addressing the area beneath the nose, the lips, and the inner area around the philtrum A-pointIt should be moved backward along with the gums and bone.
