There is a gap between your front teeth and you have been noticing it a lot lately. Maybe you have always had it and never thought much about it. Maybe it has started bothering you more as you get older. Or maybe someone mentioned it recently and now you cannot stop seeing it every time you look in the mirror. Whatever brought you here, you are in the right place.
That gap has a name. It is called a diastema. And the good news is it is one of the most straightforward things clear aligners can treat. Let us get into exactly how it works, what to expect, and what you should know before you start.
Maintain a healthy smile by brushing and flossing daily, visiting the dentist regularly, eating a balanced diet, avoiding sugary foods, staying hydrated, and using mouthwash for added protection.
First, What Is a Diastema?
A diastema is simply a gap or space between two teeth. It can appear anywhere in the mouth, but it is most commonly seen between the two upper front teeth. Some people have a single gap, others have multiple spaces across their smile.
There are a few reasons why diastemas develop, and understanding yours matters because it shapes how your treatment is planned.
Some of the most common causes include:
- A frenum that is too large or positioned too low, which is the small piece of tissue that connects your upper lip to your gum. When it sits too close to the teeth it can physically push them apart.
- Teeth that are naturally smaller than the space available in the jaw, meaning there is simply more room than the teeth can fill.
- Habits formed in childhood, such as thumb sucking or tongue thrusting, that push the front teeth forward and apart over time.
- Gum disease has caused bone loss and allowed teeth to shift and spread.
- Missing teeth that have caused neighbouring teeth to drift into the empty space and create irregular gaps elsewhere.
Knowing the cause of your diastema helps your orthodontist plan not just how to close the gap but how to make sure it stays closed once treatment is complete.
Can Clear Aligners Actually Close a Gap?
Yes, and they do it really well. Closing a diastema is one of the cases where clear aligners genuinely shine because the movement required is relatively controlled and predictable. Your aligners apply gentle, consistent pressure to the teeth on either side of the gap, gradually nudging them toward each other until the space closes.
Here is what you can generally expect from the process:
- Your orthodontist takes a full 3D scan of your teeth and bite to build your treatment plan.
- The plan maps out exactly how much each tooth needs to move and in which direction.
- You receive your aligner series and wear each set for one to two weeks, swapping through them progressively.
- The gap closes gradually over the course of treatment, usually alongside any other corrections your plan includes.
- Once treatment is complete, you move into retainer wear to hold everything in place.
For a simple single gap between the front teeth with no other bite issues, some patients see their diastema close in as little as a few months. More complex cases involving multiple gaps or bite corrections alongside the spacing will take longer, but your treatment plan will give you a realistic timeline upfront.

What You Actually Need to Watch Out For
This is the part most people do not hear until they are already mid treatment and we think you deserve to know it upfront.
Closing a gap is the straightforward part. Keeping it closed is where things require a little more attention. Gaps have a strong tendency to reopen if the right steps are not taken after treatment. Here is what actually protects your result long term:
- Wear your retainer consistently. This is non-negotiable. Once your teeth reach their final position they need to be held there while the bone and tissue around them stabilise. Skipping retainer wear even for a few weeks is enough for a gap to start creeping back.
- Address the underlying cause. If your diastema was caused by a large frenum for example, your orthodontist may recommend a minor procedure called a frenectomy to prevent the tissue from pulling the teeth apart again after treatment. This is not always necessary but when it is, skipping it is one of the most common reasons gaps return.
- Manage any gum health issues. If gum disease played a role in creating your gap, that needs to be fully under control before and during your orthodontic treatment. Moving teeth through unhealthy gum tissue leads to poor outcomes and can compromise your teeth long term.
- Consider bonding or veneers for very small teeth. In cases where the teeth themselves are naturally too narrow for the space available, aligners can close the gap but cosmetic dentistry may be needed afterward to ensure the teeth look proportionate and the gap does not simply reopen between undersized teeth.
None of these are reasons to avoid treatment. They are just things worth understanding so you go in with a full picture and come out with a result that actually lasts.
Your Next Step Is Simple
A diastema is not something you have to just live with. Whether your gap is something you have had your whole life or something that has developed over time, clear aligner treatment can close it, improve your bite, and give you a smile that you feel genuinely good about.
We plan every case with precision, and we take the time to explain every part of your treatment so you are never left guessing. We want you to understand what is happening with your teeth and why, because informed patients get better results and stay more consistent throughout their treatment.
