Types of Diastema, Causes, Treatment, and Braces for Gap Teeth

Contributors:  Amanda Napitu
Medically reviewed by:  Dr. Greg Nalchajian

Diastema is a fancy word for having a gap in your teeth. There are various types of diastema, and they have a number of causes.

You don't always have to fix a gap in your teeth, especially if it's only for aesthetic concerns, but if you have diastema as part of more severe malocclusion, then you may need treatment with orthodontics.

In this article, we'll cover the following:

  • Types of diastema (midline and mandibular)
  • Diastema treatment
  • How to close a gap without braces
  • Before and after gap teeth

Keep reading to learn all you need to know about diastema.

What is diastema?

Diastema is a gap between teeth. It's most noticeable with gappy front teeth, but gaps between teeth can occur anywhere in the mouth — top and bottom arches and molars.

diastima gap between front teeth
Some gaps are more obvious than others

According to this report in the Journal of the American Dental Association about maxillary midline diastema, between 1.6% and 25.4% of people have a general or midline diastema.

Types of diastema

There are two main types of diastema:

  • Midline diastema: This is when you have a gap between your 2 upper or lower front teeth
  • Mandibular diastema: This is a gap between any lower teeth (along the jaw)

Diastema treatment

There are various ways to close gaps in teeth, which you can read about below.

Braces for gap teeth

Braces can be used to adjust the position of diastema teeth and close gaps in the mouth.

Depending on the severity of your diastema, there are various types of braces for gap teeth that you can use. For more information about the different kinds of braces to close a gap in teeth, you can read this guide.

Larger gaps usually require treatment with traditional braces, whereas smaller gaps can be closed with clear aligners or invisible braces.

As an aside—you may need braces to close gaps in your front teeth, but spacers for teeth around your molars in the back to make more space for teeth movement!

In the video below, an orthodontist explains in greater depth what causes diastema, and how orthodontics can help:

How to close a gap without braces

Braces and aligners aren’t the only ways to fill gaps in teeth. If you want to close gaps in teeth without using other techniques, two other options are veneers and composite bonding.

Ask a dentist: When is a diastema cause for concern?

For children, a gap noticeable between front teeth isn’t generally harmful and will usually close when their permanent teeth come in. Teens and adults may choose to have a diastema closed for cosmetic reasons. Treatment options include both orthodontic closure or restorative treatment to widen the teeth, like porcelain veneers.

A diastema between posterior teeth can be a food trap, and aside from being annoying, could lead to bone loss or tooth decay. Some spaces may open as a result of missing posterior teeth putting excess forces on the remaining teeth. Finally, underlying periodontal disease is a common reason for spaces developing.

Often, however, a diastema is mainly a cosmetic issue and each patient will have to decide whether it’s something they can live with or not.

Dr. Greg Nalchajian, Nalchajian Orthodontics

Porcelain veneers

braces for diastema
Smaller gaps can be treated with veneers or bonding

A porcelain veneer is a thin cover that fits on top of your natural teeth to alter the shape and/or color. Fixing a small diastema with veneers is quite straightforward, but this treatment is only suitable for adults.

You can read more about teeth veneers.

Diastema closure with composite bonding

With diastema bonding, a composite material is applied directly to the teeth – no lab work required. The dentist builds up and shapes the composite to give the desired appearance.

You can read more about the procedure for tooth bonding here, and composite restorative procedures as an effective and affordable gap tooth treatment in this study here.

Veneers vs. bonding for a diastema

The table below summarises the two main options for treating a diastema without braces, including costs:

Porcelain Veneers

Composite Bonding

What does it involve?

A porcelain cover is applied to the teeth, made slightly wider than the teeth to fill in a gap

A composite material is added directly to the teeth to build them up, increasing the size of the teeth to fill the gap

How long does it take?

2 visits – one consultation and another 1-3 weeks later for fitting

Can be done in one visit

What does it cost?

$500 - $2,500 per tooth

$250 - $1,200 per tooth

Pros?

Long lasting and hard wearing

Fast and lower cost

Cons?

Takes away some healthy tooth, takes two dentist visits, only works for small gaps

Will need touching up – bonding lasts up to 5 years, only works for small gaps

These treatments should not be used to mask severely misaligned teeth that require orthodontic treatment.

How much does a diastema closure cost?

Diastema closure costs anywhere from $200 to $13,000, depending on the type of treatment you choose. On the low end is composite bonding, and on the higher end, veneers and braces.

Filling gaps between teeth is unlikely to be considered a medical necessity, and therefore state-funded insurance usually doesn't cover diastema closure costs in the US. Although your private insurance might.

types of diastema
Some people are happy to live with gap teeth

Children and adults with severe cases of teeth spacing, perhaps as a result of hypodontia, or congenitally missing teeth, may be eligible for braces and then dentures or dental bridges to fill the gaps. Medicaid and CHIP also covers treatment for periodontitis, which may be the cause of gaps between teeth. Read more about dental services covered by Medicaid.  

There are less expensive options like Snap-on veneers and Instasmile, but you get what you pay for, as you can see in our Instasmile reviews.

Conclusion

A diastema, or gap in your teeth, is generally not a medical concern in itself. But, there can be underlying reasons you have gaps in between your front teeth, or between other teeth, so it’s best to see a dentist for a proper assessment.

Closing gaps is reasonably straightforward and traditional braces aren’t always necessary. People with gaps in their front teeth, in particular, can get great results with removable aligner braces like Byte aligners, NewSmile aligners, Candid aligners or ALIGNERCO clear aligners. You can read more about the best invisible braces in our separate article.

FAQs

Do braces close gaps in teeth?

Yes. Especially if your diastema is more severe, braces to close a gap in teeth may be the only option available to you. If you require slight correction, at-home clear aligners are a good solution.

What can you do about space between front teeth?

If you have space in the front of your mouth, you can use orthodontic treatment to close the front teeth gap. Since this may only be a minor correction, you can use Invisalign to close gaps. In this case, you may also be able to close a gap in your teeth at home with clear aligners.

Can a retainer fix gaps in teeth?

Teeth retainers are limited in what movement they can achieve and don't deliver quick results. The normal course of action would be to have permanent or removable braces. These would correct the diastema and then you would wear a retainer to maintain the new alignment.

Removable aligner braces are probably the closest option to a retainer, since they aren't attached to your teeth like traditional braces. They are also far less noticeable than a metal wire retainer.

Are gaps in baby teeth normal?

types of braces for gap teeth
Baby teeth often have gaps as the jaw grows

Yes, gaps are normal in baby teeth. At this age, the jaw is still developing and may progress faster than teeth growth. It's also natural for there to be gaps with the first adult teeth.

I have gaps in my teeth after braces, what can I do?

Braces are designed to correct the position of your teeth and give you a properly aligned smile. If you aren’t happy with the results of your treatment, talk to the dentist who treated you. Do make sure that you wear your retainers as instructed after your treatment; this helps ensure your teeth stay in the correct position.

Does flossing create gaps in teeth?

There isn’t any reason that normal flossing would cause gaps to appear between your teeth. It is possible that you are catching your gums as you floss between your teeth. This could cause them to start to recede.

Our guide on how to floss properly will help you with the correct technique. If you are worried about your gums or gaps appearing in your teeth check that everything is ok with your dentist, it could be a sign of gum disease.

A water flosser also makes it easier to clean gaps between teeth.

How can I fix small gaps in teeth?

If you do not have severe diastema but are worried about the appearance of your smile, you may be able to get veneers to hide the gaps, although they won't actually fix the problem.

How long does Invisalign take to close a gap?

If your tooth gap is relatively small, Invisalign can take as little a six months. For minor treatments, you may be able to use Invisalign Express which costs less than Invisalign Full. If the gap in your teeth is quite large, or you have additional malocclusion problems that need to be fixed, your Invisalign treatment could take anywhere from 12 to 18 months.
