Too self-conscious about your teeth gap every time you smile in photos? It’s not just about aesthetics; if left untreated, it can get wider over time. The good news? You don't need braces to fix it. Invisible aligners can close the gap discreetly, without a single metal bracket.
You may have questions like the following:
- What causes a teeth gap?
- Can I fix my teeth gap naturally?
- How can I fix my teeth gap without braces safely?
Let’s answer all these and more in this blog.
What is Diastema or Teeth Gap?
Diastema is the medical term for a condition where patients have visible gaps or spaces between two or more teeth.
Teeth gaps can form anywhere in the mouth. It is most noticeable when the spacing is between the upper front teeth. Both kids and adults can have diastema, but gaps in children’s teeth may disappear once their permanent teeth come out.
It is not harmful, and treatment is not always necessary. However, those who are conscious of their appearance or aesthetics can close or narrow this gap.
What Causes A Gap In Your Teeth?
A single reason does not cause teeth gap (also called "diastema"), but a collection of reasons contributes to it, like your genetics, gum disease, poor oral health, wrong swallowing reflex, and so on.
You will be surprised to know how common teeth gaps are. An NLM (National Library of Medicine) report states that in a dataset of 3,989 subjects (aged between 20 and 74), a single tooth gap was found in 25% of the participants. Two single-tooth gaps were found in 16% of them.

1. Genetics
Diastema can be genetic. If anyone in your family has a teeth gap, chances are you might have that, too. Spacing occurs when your teeth are too small in relation to the size of your jawbone. And jawbone and tooth sizes are genetic.
2. Missing Teeth
Some people may have missing teeth or teeth that are smaller than others. If that is the case, teeth gaps can occur.
This usually occurs in the teeth that are on either side of the upper front teeth. If those upper lateral incisors are missing or comparatively small, then a gap can develop between the two front teeth.
3. Oversized Labial Frenum
Sounds complicated? Well, the labial frenum is the tissue that extends from the inside of the upper lip to the gum above the upper front teeth. If this tissue is more than its normal size, it can cause a gap between the two front teeth.
4. Gum Disease
In case of advanced gum disease, some teeth can migrate. This is because if you have gum disease, the inflammation can damage the bone that supports the teeth. And, when that happens, the teeth may become loose, causing a gap.
5. Poor Oral Habits
Childhood habits like lip sucking, thumb sucking, or even tongue thrusting can put pressure on the front teeth. This causes the teeth to move forward and form a gap in the front teeth.
6. Wrong Swallowing Reflex
When you swallow, the tongue presses against the roof of the mouth. This is the normal swallowing reflex.
However, some people push their tongue against their front teeth when they swallow. This repetitive pressure against the front teeth will cause them to move forward and create a gap between them.
How To Fix A Gap Between The Teeth?
There are several ways to fix diastema. While there are some ways in which you can restrict the widening of the gap naturally, clinical treatments are required to mitigate the issue completely.
You must also note that there are no clinically certified methods to close teeth gaps with home remedies. Professional treatment is always needed to fix a diastema. But some exercises can restrict the gap from widening.
What Clinical or Cosmetic Treatments Are Available For Diastema?
Traditional Braces
Braces are a common orthodontic solution to fix teeth gaps. They put pressure on the teeth and slowly move them into the right position. This helps in closing the gap.
However, these are uncomfortable and restrictive when it comes to eating and maintaining hygiene. They are visible, which can affect the aesthetics.
Teeth Gap Bands
These are small, elastic rubber bands that are similar to ligatures used by orthodontists as part of the orthodontic treatment. To use the band, you have to put it around the teeth you want to close the gap.
The pressure on the teeth supposedly helps in pulling the teeth close to each other, closing the gap. Though it sounds simple and effective, teeth gap bands can have severe consequences.
Dental Bonding
In this method, the orthodontist applies a tooth-coloured resin in the gap. Then, the professional polishes and shapes the teeth to camouflage the resin for an enhanced appearance. This doesn’t solve the issue but is a temporary solution for hiding a diastema.
Implant
The dental implant is a threaded post (made of titanium) that replaces the missing root. Once the post is healed, your dentist will position a dental crown, restoring the tooth. This closes the tooth gap.
Can I Fix My Teeth Gap Without Braces?
Yes, you can effectively fix your teeth gap without braces. While there are a lot of treatment options, Teeth Aligners can play an important role in fixing diastema.
How Do Clear Aligners Fix Teeth Gaps?
Clear aligners fix teeth gaps by applying consistent, gentle pressure to the teeth that aligns them in proper positions. Here are the steps in which Toothsi’s aligners work:
- 3D Scanning: A comprehensive digital impression of your jaw structure and teeth helps personalize the course of action for your clear aligner treatment (CAT).
- Treatment Simulation: You can see your simulated smile after you stop using your teeth aligners.
- Clear Aligners: The invisible aligners are given to you that adjust your teeth together.
- Regular Monitoring: The Toothsi app lets you consult an orthodontist at any time during and after the course of treatment.
Are Invisible Aligners Safe?
Yes, invisible aligners are extremely safe for fixing a diastema. Clear aligner therapy (CAT) has a success rate of around 80 to 90%. Let’s answer some basic questions that you may have in mind about the safety of clear aligners.
Is the material used in invisible aligners safe?
Clear aligners are made of biocompatible plastics. This means that they don’t damage the cells in your mouth if used as directed by a dental professional. You can find more on safe material usage in this study.
Are there dangers to your gums?
If you don’t maintain proper oral hygiene, there can be negative effects of using clear aligners. While invisible aligners give you the freedom to remove them (which can’t be done with braces), it is important to clean your mouth before you put your aligners on.
In case you wear your aligners over your unbrushed teeth, they can trap bacteria that can cause cavities. However, research suggests that you can maintain better gum health if you use clear aligners instead of braces.
Can clear aligners damage the roots of my teeth?
Every orthodontic treatment is about applying pressure on your teeth. There are times when the roots can shorten slightly. This process is quite normal and is called root resorption.
However, if we compare invisible aligners with traditional braces, the resorption rate is lower for aligners.
The duration taken by the aligners to close the teeth gaps or fix diastema depends on the gap size and teeth alignment.
- Small gaps generally take between 3 and 6 months
- Moderate gaps take 6 to 12 months
- Complex or larger gaps take 12 to 18 months
But with Toothsi’s support and consistent wear (around 20 to 22 hours a day), within months you can notice visible results.

How to Fix A Gap Between Teeth Naturally?
It is not possible to fix a gap between teeth naturally. However, there are certain exercises that can help stop the widening of the minor teeth gap (< 1 millimetre).
Tongue Posture Correction
It is one of the most effective natural approaches to stop the widening of the gap. In fact, it is also available in dental clinics under OMT (Orofacial Myofunctional Therapy).
The goal of the process is to stop your tongue from pushing your front teeth by retaining it to rest on the roof of your mouth.
Oil Pulling
Oil pulling is a research-backed Ayurvedic process that has antimicrobial and anti-inflammatory effects on the gum tissue. Studies have shown that coconut oil pulling reduces the levels of Streptococcus mutans (the primary pathogen that causes tooth decay).
This has an indirect effect on restricting the teeth gap. As gum inflammation is one of the reasons for minor tooth movement, oil pulling reduces the inflammation and makes the gums healthier. This, in turn, helps gums hold teeth firmly.
Proper Nutrition And Oral Hygiene
A nourished mouth will always have better structural integrity. So, having critical nutrients that nourish your teeth and gums can help restrict diastema.
Nutrient | Role | Sources |
|---|---|---|
Calcium | Strengthens the jawbone and enamel | Milk, curd, almonds, green leafy vegetables |
Vitamin D | Calcium absorption | Sunlight, fatty fish, egg yolk |
Vitamin C | Collagen for gums | Amla, citrus fruits, guava, broccoli |
Phosphorus | Tooth remineralisation | Pulses, fish, eggs, nuts, cheese |
Vitamin K2 | Calcium for bones and teeth | Paneer, fermented food, egg yolk |
In addition to nutrition, you have to maintain proper oral hygiene. You have to:
- Brush regularly
- Floss
- Use interdental brushes for more effective oral cleaning
- Massage gums
- Use mouthwash
