Fun Facts

Did You Know?

Fact 1

An open bite results when the upper and lower incisor teeth do not touch when biting down. This open space between the upper and lower front teeth causes all the chewing pressure to be placed on the back teeth.

Fact 2

If teeth are missing or small, or the dental arch is very wide, space between the teeth can occur. The most common complaint from those with excessive space is poor appearance.

Fact 3

Crooked and crowded teeth are hard to clean and maintain. This may contribute to conditions that cause not only tooth decay but also eventual gum disease and tooth loss.
