An underbite is a common dental misalignment in which the lower teeth extend further than the front teeth. This noticeable dental condition may lower a person’s self-esteem or cause them to express unintended facial expressions. While many people wish to correct this issue for aesthetic purposes, aligning an overbite can also improve your overall dental health.
Many underbite cases result from genetic factors that contribute to a small jaw shape. Excessive thumb sucking is also often a cause for misalignment as it places excess pressure on the teeth, which pushes them out of place. If you receive a jawbone injury that does not heal properly, alignment issues may occur and cause an underbite.
