He wanted to get his buck teeth fixed! hahaha
Speaking of BUCK TEETH..
Overbite is a common orthodontic condition also known as buck teeth. In this condition the top teeth overlap the lower teeth. Genetics and actions such as thumb-sucking and pencil-chewing can lead to overbite in children. When children repeatedly thrust their tongue against the back of the top teeth while swallowing, it pushes the teeth out. Children affected by overbite can hurt their protruding front teeth easily. The lower teeth may hit the root of the upper teeth when chewing. Until the age of nine children should be treated with a functional appliance that helps the lower jaw to develop properly. After this, the child should wear braces till the lower teeth come together and the upper teeth are pushed up.
