The fraenum or fraenulum that attaches the top lip to the upper portion of the gum is called the maxillary labial fraenum. An abnormally low maxillary labial fraenum is the most common cause of gapped front teeth in the upper jaw. This gap is called maxillary diastema. The abnormal fraenum is attached so low on the gum-line that it props apart the two front teeth.

It is important to close your gap because a tooth gap can cause tooth misalignment. A large gap between the front teeth could leave insufficient room for the ones next to the front teeth. This may cause tooth displacement and problems with the bite. Another reason is self-consciousness. Some people may feel embarrassed, and reluctant to smile with parted lips.

Gapped front teeth in the upper jaw close by themselves in many cases. Generally, a baby's teeth start to erupt between six and nine months. At this early age, the front teeth could be gapped and the maxillary labial fraenum attached low to the gum. By the time the child reaches its first birthday, the fraenum has probably shortened, and the eruption of more teeth has closed any gaps. If the adult front teeth are gapped, the eruption of molars helps to crowd the front teeth together. About one in 10 children have gapped adult front teeth that don't close by themselves.

Luckily, there is a simple solution to close your gap. Teeth Gap offers a product called Teeth Gap Bands. Teeth Gap Bands are like little rubber bands that wrap around the teeth which have a gap. Since the band is stretched out it pulls your teeth inward causing the tooth gap to close.
