Additional tests are found below the photos.

Crowding: Teeth may be aligned poorly because the teeth are too large for the mouth. The bone and gums over the roots of extremely crowded teeth may become thin and recede as a result of severe crowding. Poor biting relationships and an undesirable appearance may all result from crowding.

Overjet or protruding upper teeth: Upper front teeth that protrude beyond normal contact with the lower front teeth often indicate a poor bite of the back teeth, and may indicate unevenness in jaw growth. Thumb and finger sucking habits can also cause a protrusion of the upper incisor teeth. The upper teeth should not stick out from the lower teeth more than the end of a #2 pencil erasure at age 7 or about this much:

Deep overbite: A deep overbite or deep bite occurs when the lower front teeth bite too close or into the gum behind the upper teeth. When the lower front teeth bite into the palate or gum tissue behind the upper front teeth, significant bone damage and discomfort can occur.

Open bite: An open bite results when the upper and lower front teeth do not touch when biting down. This space causes all the chewing pressure to be placed on the back teeth. The excessive biting pressure and rubbing together of the back teeth makes chewing less efficient and may cause the teeth to wear.

Spacing: If teeth are missing or small for the mouth, space between the teeth can occur. The most common complaint from those with excessive space is
poor appearance.

Crossbite: The most common type of a crossbite is when the upper teeth bite inside the lower teeth (toward the tongue). Crossbites of both back teeth and front teeth are commonly corrected early at age 7 due to biting and chewing difficulties.

Underbite or lower jaw protrusion: About three to five percent of the population has a lower jaw that is to some degree longer than the upper jaw. This can cause the lower front teeth to protrude ahead of the upper front teeth creating a crossbite.

Profile Test: The lower jaw is retruded or short if the lower jaw point "A" is too far back compared to the nasal point "B" (see right female photos). The upper jaw is retruded and the lower jaw possibly is protruded
(too long) if "A" is too far out compared to "B" (see
right male photos).
