Where’s your bite? The differences between crossbites, overbites, and underbites

Malocclusion may also be referred to as an underbite, crossbite or overbite. So, what, exactly, is the difference between the three?

· Crossbites, which can involve a single tooth or a group of teeth, occur when your upper and lower jaws are both misaligned, and usually causes one or more upper teeth to bite on the inside of the lower teeth. Crossbites can happen on both the front and/or the sides of the mouth, and are known to cause wear of the teeth, gum disease and bone loss.

· Overbites, also known as “overjet,” occurs when your upper teeth overlap considerably with the lower teeth. Overbites can lead to gum issues or irritation and even wear on the lower teeth, and are known to cause painful jaw and joint problems. Overbites can usually be traced to genetics, bad oral habits, or overdevelopment of the bone that supports the teeth.

· Underbites, which occur when the lower teeth protrude past the front teeth, are caused by undergrowth of the upper jaw, overgrowth of the lower jaw, or both. Underbites can also be caused by missing upper teeth, which can prevent the normal function of front teeth ( molars). This in turn leads to tooth wear and pain in your joints and jaw.
