Stop Calling it 'Gap Teeth' or 'Open Teeth' Here is the Correct Word to Say and Other Health Facts

Many people refer to the space between the front teeth as “gap teeth” or “open teeth,” but did you know there’s actually a medical term for it? The correct word is “diastema.” A diastema is a space or gap between two teeth, most commonly the upper front teeth. While it is often seen as a unique beauty trait in some cultures, it can also raise important dental health concerns depending on its cause.

In Kenya and other parts of the world, having a diastema is sometimes viewed as attractive and even considered a sign of good luck or beauty. In fact, many celebrities like singer Madonna and South African actress Mshoza have proudly embraced theirs. However, not all diastemas are harmless.

Diastemas can occur for several reasons. For some people, it’s genetic—passed down through family lines. For others, it might be caused by habits such as thumb sucking, tongue thrusting, or even poor dental alignment. Sometimes, a diastema may be a result of an oversized labial frenum, which is the tissue connecting your upper lip to your gums. If it extends too far between the front teeth, it can push them apart.

While most diastemas are harmless, others may lead to oral complications. For instance, large gaps may affect the way you bite and chew, or make it easier for food particles to get trapped, leading to plaque buildup, gum disease, or tooth decay. In children, gaps might close naturally as adult teeth come in. However, in adults, treatment options include braces, dental bonding, veneers, or frenectomy surgery in case the frenum is the issue.

It’s important to remember that diastema is not a disease—it’s a dental condition. If it doesn’t bother you or cause health issues, there’s no pressure to close it. But if it affects your confidence or oral health, a visit to a dentist or orthodontist can help you explore safe and affordable solutions.

So next time you see someone with a gap between their teeth, don’t just call it “open teeth”—now you know the correct and respectful word is diastema. And behind that smile might be a story of culture, genetics, or just pure confidence
