A confident smile has the ability to leave a lasting impression, but many people don't enjoy the privilege of smiling freely. One common concern that people face is the gap between teeth . These spaces can occur between any two teeth, and while some people accept them as part of their unique characteristics, others may consider trying to close these gaps for cosmetic or oral health reasons.
But what actually causes teeth gaps? Are they purely genetic, or do daily habits play a bigger role in shaping your dental alignment? Let’s find out!
Understanding Teeth Gaps
In scientific language, teeth gaps are called diastema . These are basically small or large gaps between two teeth that occur in any area of the upper and lower arch.
Symptoms of Diastema
Some of the symptoms of teeth gaps or diastema are as follows:
- Visible spacing between two or more teeth
- Food frequently gets stuck between teeth
- Speech difficulties, such as a slight lisp
- Gum sensitivity due to excessive exposure
- The presence of black triangles
If you notice any of these symptoms, it may be time to explore possible causes and solutions.
Types of Teeth Gaps
Not all teeth gaps are the same. They can vary in size and severity. Some types of diastema or gaps between teeth are explained below:
Midline Diastema

It is the most common type of tooth gap or diastema. It refers to a noticeable tooth gap between the two upper or lower front teeth.
Pathalogic Gaps

These are the spaces that are created by missing teeth. It often leads to misalignment of surrounding teeth.
Maxillary Diastema

A gap between the upper teeth of the jaw is called maxillary diastema. The gap commonly occurs between the two upper front teeth.
Mandibular Diastema

The tooth gap that appears in the lower jaw is called mandibular diastema. It can appear in any area of the lower arch.
Open Gingival Embrasures

The gaps that appear in the form of black triangles between the teeth near the gum line are known as open gingival embrasures .
Genetics vs. Lifestyle: The Real Cause
There are multiple potential causes of tooth gaps. Some of them are preventable but there are others that you will not be able to avoid. Among all the causes, the most common are genetics and lifestyle habits.
The Genetic Factor
If your parents or grandparents had gaps between their teeth, there’s a strong chance you inherited this trait. Genetic factors influencing gap teeth include:
Jaw Size vs. Tooth Size
If your jawbone is disproportionately larger than your teeth, spacing can occur.
Missing or Extra Teeth
Some people may develop fewer or extra teeth, which can impact alignment.
Frenulum Attachment
A thick or extended labial frenum can push the front teeth apart, creating a midline tooth gap.
Lifestyle Habits
While genetics play a role, certain behaviors and habits can also greatly contribute to gap teeth. Some of these habits are explained below:
Thumb-Sucking & Pacifier Use
Prolonged thumb-sucking or use of pacifiers in childhood can put pressure on the front teeth, causing gaps.
Tongue Thrusting
Tongue thrusting refers to a swallowing reflex where the tongue pushes against the front teeth. It can create gaps over time.
Gum Disease & Black Triangles
Poor oral hygiene can lead to gum recession and black triangles, making gaps more prominent.
Does Flossing Create Gaps in Teeth?
A common myth! Flossing doesn’t create gaps, but improper flossing techniques can contribute to gum recession, which may make gaps appear larger.
Solutions for Teeth Gaps
There’s no treatment needed for children whose baby teeth are falling out because most of the gaps disappear by the time they develop all their permanent teeth.
You don't have to treat your diastema as an adult either if you’re okay with it or if it is not causing any oral health risks. However, if you want to fix it, there are multiple solutions to close a tooth gap, depending on severity, budget, and personal preference. Here’s a breakdown of the most effective treatments:
Clear Aligners
Clear aligners are a popular, discreet, and effective way to close gaps gradually. Made of clear plastic, they are virtually invisible. Additionally, they are comfortable to wear and can be removed for eating and cleaning. Another advantage of clear aligners is that they are more affordable than traditional braces, making them the best alternative.
Braces
Traditional metal braces use brackets and wires to shift teeth into place. While effective, they are more visible and require longer treatment times. They are also very uncomfortable to wear and require frequent dental visits for necessary adjustments.
Dental Implants
For gaps caused by missing teeth, dental implants are a permanent solution. They look and function almost like natural teeth. Also, they are helpful in preventing further bone loss in the jaw. It is a more invasive option as it involves surgical placement.
Veneers
Veneers are thin porcelain shells, bonded to the front of the teeth to mask gaps. These are custom-made for each patient. While offering an instant transformation, they require some enamel removal, can be costly, and are more suitable for small gaps.
Dental Bonding
A quick and affordable fix, dental bonding involves applying a tooth-colored resin to fill in the gaps between one or more smaller teeth. This resin is hardened with the help of light rays. However, It is not as durable as other solutions and may require periodic touch-ups.
Frenectomy
If a thick frenum is causing the tooth gap, a simple surgical procedure called frenectomy can be performed to remove the trouble-causing frenum. This is usually done before the orthodontic treatment to allow teeth to close naturally or with aligners.
