Buck Teeth: What are They and Is It Important to Fix Them?

Among the countless dental problems that people face, buck teeth is the most common. This often ignored dental condition is the result of certain childhood habits like thumb-sucking, tongue thrusting, etc. But it can also occur naturally. Sometimes, the positioning of the lower jaw is such that it exerts pressure on the teeth, which in turn pushes them forwards.

Many people choose to leave their buck teeth untreated. While it does not pose any major health consequences, in some severe cases it becomes necessary to get them treated.

Also known as overjet, buck teeth are characterized by a horizontal overlapping between the upper and lower front teeth. The severity of this condition depends upon the overlapping between the teeth. In some severe cases, these protruding teeth make it  impossible for you to close your lips.

For cosmetic purposes, some people chose to treat their crooked teeth with veneers or artificial teeth. Others rely on braces to correct their alignment.

Buck teeth can hinder the chewing process which can interfere with your digestion. They may also hurt your teeth other than them, gums, and tongue.
