Common Orthodontic Concerns

  • Class II
  • Class III
  • Crossbite
  • Crowding
  • Deep Bite
  • Openbite
  • Spacing

Class II

Class II problems are those where an abnormal bite relationship is present causing the upper jaw and teeth to rest in front of the lower jaw and teeth. This can cause a convex facial profile and a recessed chin. A Skeletal Class II problem arises when the upper back molars sit too far forward in relation to the lower back molars.

Class III

Class III problems are almost always inherited. With this class, the lower jaw and teeth sit in front of the upper jaw and teeth. This causes the lower jaw to look oversized, but oftentimes, it is correctly sized and the upper jaw is simply too small. Multiple treatment options are available to address a class III problem.

Crossbite

Posterior crossbites are usually caused by a narrow upper jaw or a lower jaw that is abnormally wide. When the jaw widths do not match, the patient must move the jaw side to side in order to chew properly. This is what gives the condition its name. It can happen on just one side of the jaw or on both sides simultaneously.

Crowding

Out of all orthodontic problems that can occur, crowding is easily the most common. This can be caused by many factors, but it tends to be due to the teeth and jaw not being sized well for each other. Because crowding can cause other problems with oral and general health, it should be corrected, usually with braces alone.

Deep Bite

A deep bite occurs when the front teeth have an excessive vertical overlap. Usually, this happens when the upper and lower jaws are of different lengths. This can cause excessive eruption of the upper and lower incisors and force the lower teeth to bite the roof of the mouth.

Openbite

Open bite can impact the front and back teeth. An anterior open bite impacts the front teeth and occurs when there is a lack of vertical overlap due to jaw problems or habits like thumb sucking. A posterior open bite impacts the back teeth, preventing them from meeting vertically and harming the function of the jaws.

Spacing

Spaces between the teeth are the second most common orthodontic problem. It is usually due the jaws and teeth not being sized well for each other. This problem is easy to address, usually needing nothing more than braces.
