Causes of Gap Teeth

As prosthodontists and providers of Invisalign treatment, we at the Oyster Bay Family Dentists repair a lot of gap teeth and overbites. But what causes these sorts of malocclusions to form in the first place? Today we’re looking at the origins of diastema (spaces) between the upper front incisors and what a patient’s treatment options are.

Diastema may be the result of something preventing the teeth from drawing together. In the upper front teeth, this would likely be the labial frenum, the strip of tissue connecting the inside of the lip to the jaw. When this tissue is too thick, there are surgical options for reducing it, including the use of our diode laser. Once the frenum is reduced and if there are no other bite issues, it may be possible to close the gap simply by applying veneers.

A more common reason for gap teeth is tongue thrusting. This habit can also result in an overbite and can push the teeth at an angle, requiring the patient to get orthodontic treatment. Tongue thrusting may be due to psychological stress, but it could also be an involuntary reflex triggered by throat obstructions. The assistance of an ear, nose, and throat doctor may be required to tell for sure. In children, sucking on a thumb or pacifier also increases the risk of gap teeth or an overbite developing.
