The first two teeth are butterfly teeth. Will their mouths stick out?

Yes The first two teeth are butterfly teeth, which will make the mouth protrude forward. Butterfly teeth refer to the maxillary anterior teeth (especially incisors) protruding forward when occluding, which is more prominent than other teeth. This feature makes the outline of the mouth convex, similar to the shape of a butterfly, hence the name butterfly tooth. The formation of butterfly teeth may be related to factors such as uneven tooth arrangement and maxillary growth. Butterfly teeth have no obvious influence on chewing and pronunciation, but may have some influence on personal image in aesthetics.
