Occlusion refers to the way your upper and lower teeth fit together when at rest. When your upper and lower teeth do not fit properly, the condition is known as malocclusion. Because the teeth do not rest together ideally, undue stress and strain is placed on the jaw muscles, which can lead to TMJ dysfunction. The two most common forms of malocclusion, overbite and underbite, are typically corrected through the use of braces. To better understand the causes of malocclusion, Lake Orion dentist Dr. Brad Greenfield outlines the circumstances of an overbite and an underbite.

Overbite Facts

• In a typical human jaw, the upper teeth extend past the lower teeth by about 3-5 mm. When the extension exceeds 5 mm, the bite is abnormal and labeled as an overbite.
• An overbite can be genetic (inherited from the parents). However, because the jawbone is still soft at young ages, thumb sucking and excessive pacifier use can exacerbate the problem.  
• Like most malocclusion, an overbite can usually be corrected with the use of braces.
• The extent of an overbite can be so minor as to be unnoticeable, or so severe as to visibly alter the appearance and structure of your face.
