Overcrowded teeth occur when there is simply a lack of room within your jaw for all of your teeth to fit normally. When left untreated, overly crowded teeth can cause an increased chance of gum disease as your teeth are harder to clean and can prevent the normal function of teeth.

Widely spaced teeth occur when you have extra space within your jaw. This could be due to small sized teeth, abnormal growth of the jaw bones, genetics, missing teeth and/or tongue protrusion. When teeth are missing, this issue can also be caused by the other teeth shifting due to extra space. Spacing issues can lead to some periodontal diseases including gingivitis and periodontitis that, left untreated, can lead to tooth loss.

Crossbites occur when the upper and lower jaws are both misaligned. It usually causes one or more upper teeth to bite on the inside of the lower teeth, and can happen on both the front and/or the sides of the mouth. This issue can cause wear of the teeth, gum disease and bone loss.

Overbites occur when the upper teeth overlap significantly with the lower teeth. It's typically caused by either genetics, bad oral habits, or over development of the bone that supports the teeth. This issue can lead to gum problems or irritation, and/or wear on the lower teeth and can cause painful jaw and joint problems.

Underbites occur when the lower teeth protrude past the front teeth, usually caused by undergrowth of the upper jaw, overgrowth of the lower jaw, or both. It can also be caused by missing upper teeth. This issue can prevent the normal function of front teeth or molars which can lead to tooth wear. It can also cause painful jaw and joint problems.
