Protrusion of teeth is a common condition in South East Asia. The top and bottom teeth may be inclined forwards or positioned too far forwards in the jaws. This also makes the upper and lower lips protrude outwards.
If the teeth are small and there are existing spaces between the teeth, we could utilise the spaces to pull the front teeth inwards with braces.
In cases with normal-sized teeth, four teeth may have to be removed, to provide space to move the front teeth backwards with braces. Following orthodontic, the lips would also move inwards, resulting in a more pleasing smile and improved lip posture.
Inclination of upper and lower teeth is reduced after four teeth were extracted. Lips are not so protruded following orthodontic treatment.
