What is an underbite?

An underbite occurs when the lower teeth are too far forward or the upper teeth too far back.

What causes an underbite?

An underbite is usually caused by undergrowth of the upper jaw, overgrowth of the lower jaw, or both. It can also be caused by missing upper teeth.

During infancy, the jaws and tooth structure are very susceptible to pressures and habits like thumb sucking, tongue thrusting and prolonged use of pacifiers and feeding bottles which may also lead to an underbite.

What problems does an underbite cause?

Dentists recommend that underbites be corrected early because they can cause poor functioning of the teeth, and can lead to digestive problems.
The molars of a person suffering from this condition will not fit together correctly, often resulting in chewing difficulty.

Incorrect seating of teeth will also result in uneven wear and will result in damage to teeth. In many cases, the upper teeth will interfere with the lower gums and could even damage them.

It is recommended to get treatment for a underbite early to prevent any further problems.

How do you treat an underbite problem?

Treatment of an underbite is often more involved than overbites as orthodontists will need to modify the jaw growth or extract some teeth. Each case is a little different but some severe cases may need surgical intervention for correction.
