What is a Diastema?
A diastema is the clinical term for a gap between two teeth. Although it can occur anywhere in the mouth, it’s most commonly seen between the two upper front teeth.
For some people, a gap is purely a cosmetic feature and doesn’t require treatment. In other cases, it may be associated with the way the teeth have developed, missing teeth or differences in tooth size. An orthodontic assessment can help determine what’s causing the gap and whether treatment is recommended.
What Causes a Diastema?
A gap between the teeth can develop for several reasons. Genetics is one of the most common causes, but tooth size, jaw size and the way the teeth erupt can also play a role.
Some people have a gap because a tooth is missing or smaller than expected, while others have additional space between their teeth due to the way their jaws have developed. In children, a gap between the upper front teeth is often a normal stage of development and may close naturally as the adult teeth erupt.
Can a Diastema Cause Problems?
Food Trapping
Food can sometimes become trapped between widely spaced teeth, making cleaning more difficult.
Tooth Position
A gap may allow neighbouring teeth to shift over time, depending on the underlying cause.
Smile Appearance
Some people are happy with the appearance of a gap, while others choose orthodontic treatment because they would prefer a more even smile.
An Underlying Dental Issue
In some cases, a gap may be a sign of another issue, such as a missing tooth or differences in tooth size. Identifying the cause is an important part of planning treatment.
How Is a Diastema Treated?
Treatment depends on what’s causing the gap. For many patients, braces can be used to gradually move the teeth together and create a more even smile.
However, orthodontic treatment isn’t always about simply closing the space. If the gap is related to a missing tooth or differences in tooth size, treatment may involve creating or maintaining the right amount of space as part of a broader treatment plan. In some cases, orthodontic treatment is coordinated with your general dentist or another dental specialist to achieve the best long-term result.

Frequently Asked Questions
Is a gap between the front teeth normal?
Yes. A gap between the front teeth is common, particularly in children as the adult teeth develop. In many cases, these spaces close naturally, while others remain into adulthood.
Can braces close a gap between my teeth?
In many cases, yes. Braces can gradually move the teeth together but the most appropriate treatment depends on what’s causing the gap.
Why do I have a gap between my front teeth?
A gap may be caused by genetics, differences in tooth or jaw size, a missing tooth or the way your teeth have developed. An orthodontic assessment can determine the underlying cause.
Will a gap between my child's front teeth close naturally?
Often, yes. A gap between the upper front teeth is a normal stage of development for many children and may close as the adult teeth erupt. If the gap remains after the permanent teeth have come through, it’s worth arranging an orthodontic assessment.
Will the gap come back after orthodontic treatment?
Teeth naturally have a tendency to move over time, which is why wearing your retainer as instructed is an important part of maintaining your result after treatment.
