Many people call the space between two teeth “gap teeth” or “open teeth.” But the proper dental term for a noticeable gap between teeth is diastema.
What Is Diastema?
A diastema is a space or gap between two teeth. It can occur anywhere in the mouth, but it is most commonly noticed between the two upper front teeth.
For some people, the gap has been present since childhood. For others, it may develop or become more noticeable over time.
Why Do Some People Have a Gap Between Their Teeth?
Several factors can contribute to diastema, including:
Natural tooth and jaw development
A gap caused by the size or position of the teeth
A large or low-positioned frenum, the tissue connecting the lip to the gum
Missing teeth
Certain habits during childhood
Gum disease that causes teeth to shift
Is Diastema Dangerous?
Not necessarily. A gap between the teeth is often simply a natural variation and may not require treatment.
However, if a gap suddenly develops, becomes larger, or appears alongside bleeding gums, loose teeth, swelling, or pain, it’s a good idea to see a dentist.
Can It Be Fixed?
If someone wants to close a gap for cosmetic or dental reasons, treatment options may include braces, clear aligners, bonding, veneers, or other dental procedures, depending on the cause and size of the gap.
