Health concerns are often the primary consideration for adult treatment.  Crooked teeth and bad bites may seriously affect oral health.  Orthodontic treatment might help prevent many serious potential problems such as tooth decay, gum disease and eventual tooth loss.

One of the most prevalent adult orthodontic problems is a tooth that is too crowded.  These teeth are extremely difficult to clean, making them more prone to decay, even if good oral hygiene is practiced.  Conversely, spaces can also be a problem, especially if the early loss or extraction of teeth causes healthy teeth to tip into open spaces.  Deterioration of the supporting bone may occur, causing teeth to become loose.

Protruding front teeth, in addition to being unattractive, do not meet properly during chewing.  This can cause abnormal wear of tooth surfaces, as well as excess stress on supporting bone and gum tissue.  The stress on supporting tissues might contribute to gum disease and possibly lead to the loss of teeth.

Orthodontic problems are not always confided to the mouth.  Disorders of the temporomandibular joints, which connect the lower jaw to the skull, may be one of the reasons why millions of people suffer from chronic headaches, earaches and facial pain.  Though tempromandibular disorders (TMD) may have a variety of causes, treatment sometimes may include orthodontic treatment.
