If there is no space between the baby teeth, then there will not be enough room for permanent teeth. Baby teeth or permanent teeth are crowded or overlapped.
Noticeably large gaps between the teeth.
Upper dental protrusion
The top teeth stick out too far (“buck teeth”). Most common orthodontic problem and easier to correct if treated early.
The upper front teeth overlap the lower front teeth too much and the lower front teeth are barely visible.
The lower front teeth stick out further than the upper front teeth.
The front teeth do not touch when the back teeth are touching.
The midline of the upper teeth does not line up with the midline of the lower teeth.
An upper tooth fits inside a lower tooth or the upper back teeth are narrower than the lower teeth.
