Diastema or Gap Between Teeth – Causes, Treatment & Prevention

Diastema or Gap Between Teeth

What is Diastema?

Diastema is a condition where you have a noticeable gap between teeth. It is found in both kids and adults. The gap in teeth can be among any teeth. But the gap in the front teeth is more visible. Sometimes this gap gets filled on its own with the eruption of permanent teeth in kids.

It is merely an aesthetic concern for some people, but it can pose serious dental health threats for others. Read on to learn about the causes, symptoms, prevention, and treatment of diastema.

What Causes Gap Between Teeth?

The following are the possible causes of diastema:-

  • Natural Growth

Sometimes, gapped front teeth are the result of natural growth in kids. It is pretty common between the age group of 6-8 years. But this gap disappears in most cases with the formation of upper canines.

  • Abnormal Position, Size & Shape of Teeth

If the shape, size, and position of your teeth are unusual, the possibility of a gap increases. These teeth can’t get the required pressure and support from each other to prevent them from drifting apart.

  • Missing Teeth

The most common occurrence of missing teeth is underdeveloped or missing surrounding teeth of your upper front teeth. They are also called upper lateral incisors. This condition leads to gapped front teeth.

  • Outgrown Labial Frenum

The labial frenum is a tissue covering the inside of the upper lip and the gum above the upper front teeth. If this tissue outgrows, it can lead to a gap in teeth.

  • Periodontitis

A gap between your teeth can also be the result of periodontitis. It is a kind of gum disease or infection that damages the tissues and teeth bone. As a result, your teeth get loose and form a gap.

  • Improper Swallowing Reflex

Correct swallowing reflexes make your tongue press against the roof of the mouth. In contrast, incorrect swallowing pushes your tongue against your front teeth. This constant pressure can eventually convert into gapped front teeth.

  • Wrong Habits

Bad habits like biting lower lips and sucking the thumb or finger can cause diastema in a kid. And an adult can invite it by having a tongue piercing. The pierced stud can disturb the formation of front teeth by budging them constantly.

  • Falling of Baby Teeth

A gap between teeth can emerge due to the falling of baby or permanent teeth. But these kinds of gaps close with the eruption of permanent teeth.

  • Dental Bonding

Dental bonding is helpful in teeth gap filling when the gap is because of one or more smaller teeth. In this treatment, the resin is applied to the surface of your teeth. And it is hardened with the help of light rays.
