Often your gums recede making your teeth appear longer.

Gum recession is the process in which the margin of the gum tissue that surrounds the teeth wears away, or pulls back, exposing more of the tooth, or the tooth’s root. Receding gums may be one of the first signs of gum disease. When gum recession occurs, “pockets,” or gaps, form between the teeth and gum line, making it easy for disease-causing bacteria to build up. If left untreated, the supporting tissue and bone structures of the teeth can be severely damaged, and may ultimately result in tooth loss.

Gum recession is a common dental problem. Most people don’t know they have gum recession because it occurs gradually. The first sign of gum recession is usually tooth sensitivity, or you may notice a tooth looks longer than normal. Often a notch can be felt near the gum line.
