Gaps between teeth, called diastema, can usually be closed with dental bonding, porcelain veneers, or orthodontic treatment, depending on the size of the gap and your dental health. At Sola Dental Spa in Staten Island, Dr. Anne Gershkowitz evaluates each patient's gap, bite, and goals before recommending a treatment plan, since a small gap and a wide gap often call for different approaches. Closing a longstanding gap is one of the more common reasons patients pursue a smile makeover.
What Causes Gaps Between Teeth?
Diastema most often appears between the two front teeth, though it can occur elsewhere in the mouth. It is more common in children, and many childhood gaps close on their own as permanent teeth come in. In adults, a persistent gap is frequently linked to genetics, the size of the teeth relative to the jaw, or a labial frenum, the tissue connecting the lip to the gum, that is larger than average.
Occasionally a gap is a sign of gum disease that has caused teeth to shift or loosen. If that is the case, periodontal treatment needs to happen first, since closing a gap cosmetically will not resolve an underlying gum problem. A dental exam is the only reliable way to tell the difference between a purely cosmetic gap and one connected to gum health.
What Are the Treatment Options for Closing a Gap?
| Treatment | Best For | How It Works |
|---|---|---|
| Dental bonding | Small to moderate gaps | Tooth-colored resin is applied and shaped to close the space |
| Porcelain veneers | Larger gaps or gaps paired with other cosmetic concerns | Custom shells cover the front of the teeth to close the gap and refine shape |
| Traditional braces or clear aligners | Gaps caused by tooth position or spacing across the arch | Teeth are gradually moved into a closed, aligned position |
Bonding tends to be the fastest option for a single small gap, often completed in one visit. Veneers take a bit longer since they are custom-fabricated, but they can address a gap alongside other concerns like discoloration or shape in the same treatment. Orthodontic options work differently: rather than covering the gap, they close it by moving the teeth themselves, which can be the better long-term solution when spacing issues affect multiple teeth.
“There is no single right way to close a gap. A small space between the front teeth might be solved with bonding in a single visit, while a wider gap tied to how the teeth are spaced across the arch is often better served by orthodontics. That is exactly why we look at the whole mouth before recommending a plan.”

Cost and appearance both factor into this decision. Bonding is generally the least expensive option and the quickest to complete, but it is also the least durable of the three. Veneers cost more and take longer to place, but tend to hold their color and shape well over time. Orthodontic treatment addresses the underlying spacing rather than covering it, which is worth considering if the gap is one of several alignment concerns rather than an isolated issue.
Can Orthodontics and Cosmetic Treatment Be Combined?
Yes, and for some patients this combination gives the most complete result. Orthodontic treatment can close the gap itself by shifting the teeth into position, while bonding or veneers refine color, shape, or minor imperfections afterward. To learn more about combining approaches, see our article on can you combine orthodontics with a smile makeover.
How Long Does It Take to Close a Gap Between Teeth?
Timelines vary considerably by treatment and by the size of the gap. Bonding is typically completed in a single appointment. Veneers generally require a couple of visits to design, fabricate, and place. Orthodontic treatment takes the longest, since it works by moving teeth gradually, and your dentist or orthodontist can give you a timeline based on your specific case rather than a general estimate, since treatment length varies widely from patient to patient.
What Happens During a Consultation for a Gap Makeover?
Your dentist examines the gap itself along with your bite, gum health, and the position of neighboring teeth. This exam also checks for any underlying issue, like gum disease, that needs to be addressed before cosmetic treatment. From there, you will discuss which option, bonding, veneers, orthodontics, or a combination, best fits the outcome you want.

Frequently asked questions
Is a gap between teeth always a cosmetic issue?
Not always. Most gaps are simply a variation in how the teeth developed, but a gap can sometimes signal gum disease or tooth movement, which is why a dental exam should come before cosmetic treatment.
Is bonding a permanent fix for a gap?
Bonding is durable but not permanent. It can chip or stain over time and typically needs touch-ups or replacement after several years, depending on how well it is cared for.
Will closing my gap with veneers require removing tooth enamel?
Traditional veneers typically require a small amount of enamel removal to fit properly, though the exact approach depends on the size of the gap and the veneer material your dentist recommends.
Can clear aligners close a gap as effectively as traditional braces?
For many types of spacing, yes. The right choice between aligners and braces depends on the size and location of the gap as well as your bite, which your dentist or orthodontist will assess directly.
Do gaps come back after treatment?
Gaps closed with bonding or veneers generally stay closed unless the restoration is damaged. Gaps closed with orthodontics can shift back over time without a retainer, which is why a retention plan matters after treatment finishes.
