A diastema is the dental term for a gap between two teeth, most often the two upper front teeth. It is a common feature, not a flaw, and plenty of people keep it without ever treating it.
Still, if it bothers you, there are several ways to close it. This article covers why gaps form, when treatment actually makes sense, and what your options are.
What Causes a Diastema
Tooth and Jaw Size Mismatch
When the jawbone is slightly larger than needed to fit the teeth closely together, small gaps can appear between them. This is one of the most common causes of a diastema.
Missing or Undersized Teeth
If a tooth is naturally smaller than average, or if a tooth is missing altogether, the surrounding teeth may not fully close the space between them.
Extra Tissue Between the Front Teeth
Sometimes a piece of tissue, called a frenum, extends further than usual between the two upper front teeth, physically keeping them apart. This is a specific and treatable cause of a persistent gap.
Habits
Habits such as tongue thrusting, where the tongue pushes against the front teeth repeatedly, can gradually widen a gap over time, especially in children.
Gum Disease
In adults, gum disease that leads to bone loss can cause teeth to shift and create new gaps that were not there before.
Do You Actually Need to Treat It
A diastema is not a health problem on its own. Many people keep their gap by choice, and it does not put your teeth at any additional risk if your bite and gums are otherwise healthy.
Treatment becomes worth considering if the gap bothers you cosmetically, or if it is linked to an underlying cause like gum disease or a habit that is actively getting worse.
Note: If a gap between your teeth is new, widening, or accompanied by loose teeth or bleeding gums, see a dentist soon. This combination can point to an active gum health issue rather than a simple cosmetic gap.
Treatment Options
Composite Bonding
Bonding is a fast, affordable way to close a small to moderate gap by adding resin to the sides of the two teeth. It is often the first option discussed for a straightforward diastema, and it is the same approach used for black triangles near the gum line, which are a closely related type of gap.
Porcelain Veneers
For larger gaps, or when the gap is one of several cosmetic concerns, veneers can close the space while also adjusting the shape and color of the teeth involved.
Orthodontic Treatment
Braces or clear aligners physically move the teeth together to close the gap from the root, rather than adding material to the visible surface. This is a longer process but addresses the position of the teeth directly.
Frenectomy
If the gap is caused by an overextended piece of tissue between the front teeth, a minor procedure called a frenectomy removes or repositions that tissue. This is sometimes combined with orthodontic treatment for a lasting result.
Table: Matching Cause to Treatment
| Cause | Typical Treatment |
|---|---|
| Jaw and tooth size mismatch | Bonding, veneers, or orthodontics |
| Extra frenum tissue | Frenectomy, often with orthodontics |
| Tongue thrusting habit | Habit correction, sometimes with orthodontics |
| Missing or small tooth | Bonding, veneer, or replacement option |
| Gum disease related shifting | Gum treatment first, then cosmetic fix |
Choosing Between Bonding and Orthodontics
Bonding closes the visible gap without moving the teeth themselves, and it is finished in a single visit. Orthodontic treatment physically closes the gap by shifting the roots, which takes longer but can be a more permanent structural fix.
For a small, stable gap, many patients choose bonding for its speed and simplicity. For a larger gap or one linked to a tooth position problem, orthodontics may give a more lasting result.
What Happens if You Leave It Untreated
Leaving a diastema untreated causes no harm on its own, as long as your gums and bite are healthy. Some gaps stay exactly the same size for years without any dental intervention needed.
The exception is when the gap is caused by an active issue like gum disease or a habit that continues to widen it. In those cases, the underlying cause needs attention regardless of whether you treat the gap cosmetically.
Frequently Asked Questions (FAQs)
Is a diastema always a problem that needs fixing?
No, a gap between teeth is often just a natural variation and does not require treatment unless it bothers you or is linked to an underlying issue. Many people keep their diastema without any negative effect.
Can a diastema close on its own?
It generally does not close without some form of treatment, and in some cases, such as an active habit or gum disease, it can widen further over time. A dentist can tell you if your specific gap is stable or changing.
Which is faster, bonding or braces, for closing a gap?
Bonding is much faster, often finished in a single visit, compared to braces, which can take months. Braces address the position of the tooth root, while bonding only changes the visible surface.
Do children need treatment for a diastema?
Many children have a gap between their front teeth that closes naturally as adult teeth come in. A dentist can advise whether a specific gap needs monitoring or treatment based on the child's age and dental development.
Can a frenectomy be done alone without braces?
Yes, but it is often combined with orthodontic treatment for a more stable, lasting result when the gap is significant. Your dentist will advise based on your specific case.
Will the gap come back after bonding?
Bonding that closes a gap is generally stable as long as the underlying cause was not an active habit or ongoing gum issue. Addressing any underlying cause first protects the result.
Is a gap between teeth linked to any health risk?
On its own, no, a diastema does not carry a health risk if your gums and bite are otherwise healthy. It only becomes a concern when linked to gum disease or a habit that continues to change your bite.
If a gap between your teeth is something you want addressed, or if it seems to be changing, a dental exam is the right next step.
