Common Problems

Upper Front Teeth Protrusion

The appearance and function of your teeth are impacted by this type of bite. It is characterized by the upper teeth extending too far forward or the lower teeth not extending far enough forward. These bite problems, typically referred to as a Class II problem, are generally due to inherited traits.

Common Problems


The upper front teeth extend out over the lower front teeth, sometimes causing the lower front teeth to bite into the roof of the mouth. Generally, a discrepancy between the length of the upper and lower jaws causes this type of bite.

Common Problems


The upper teeth sit inside the lower teeth, which may cause tooth stratification and misaligned jaw growth. If a patient has a narrow upper jaw, it may cause them to move their lower jaw forward or to the side with closing into a bite.

Common Problems


Proper chewing is impacted by this type of bite, in which the upper and lower front teeth do not overlap. Openbites cause a number of unwanted habits, such as tongue thrusting.

Common Problems


Crowding occurs when teeth have insufficient room to erupt from the gum. Crowding can often be corrected by expansion, and many times, tooth removal can be avoided. This is known as one of the most common problems associated with those needing orthodontic care.

Common Problems


Spacing between teeth is another common problem associated with those needing orthodontic care. Spacing problems may be caused by missing teeth or the relationship between the jaw size and the size of the teeth.

Common Problems

Dental Midlines Not Matched

This type of problem is caused when the back bite does not fit and match appropriately, which may negatively impact jaw and proper dental function.

Common Problems


In this type of bite (or a Class III problem), the lower teeth and jaw extend out over the upper jaw structure. This, too, is generally attributed to inherited characteristics. In most cases, the lack of development in the upper jaw is the cause of a Class III problem.

Common Problems

TMJ (Temporomandibularjoint) Disorders

The "Temporomandibular Joint," more commonly referred to as the "jaw joint," assists in the basic opening and closing movements of the jaw. Unfortunately, this joint is a common area for recurring pain. Although conventional wisdom suggests that "popping" sounds in the jaw indicates a TMJ dysfunction, this is not always true. Many times, your jaw is functioning properly even if a "popping" sound is present when chewing or talking.

Some factors that may cause a TMJ disorder are: Internal joint derangements, arthritic joints, anatomical dispositions, Intra or Extra Capsular Disorders, Stress, Clenching or Grinding of teeeth, habits such as excessive gum chewing, wide or prolonged mouth opening, or Facial injuries.
