A gap between teeth, medically known as diastema, can add character to a smile, but for many, it raises questions and concerns—especially if it begins to widen over time.
If you’ve noticed this happening, you’re probably wondering, “Why do teeth gaps increase?”
Diastema can result from a variety of factors, with the size and placement of the gaps often influenced by the underlying cause. While many individuals are primarily concerned about the aesthetic impact of these gaps, it’s important to understand that they can also affect oral health in some situations.
What Exactly is Diastema?
Diastema often appears between the two front teeth and is known as midline diastema. The size of these gaps can vary from barely noticeable to quite prominent. While diastema is generally harmless to oral health, in some cases, it can signal the presence of underlying gum disease.
Why Do Teeth Gaps Increase?
There are multiple reasons why teeth gaps may expand.
Let’s explore them in detail.
Missing or Undersized Teeth
Gaps may develop when certain teeth are missing or smaller than usual. This is particularly common with the upper lateral incisors—the teeth located next to the two upper front teeth. If these lateral incisors are absent or undersized, it can create a noticeable gap between the upper front teeth.
Oversized Labial Frenum
An enlarged labial frenum, the tissue that connects the inside of the upper lip to the gum above the upper front teeth, can also lead to gap formation. When this tissue is abnormally large, it can put pressure on the front teeth, pushing them apart and causing a visible gap.
Jawbone and Tooth Size Mismatch
When teeth are relatively smaller than the jawbone, gaps may form between them. This imbalance in size is often linked to genetics, which explains why gaps between teeth frequently occur in families.
Gum Disease and Tooth Shifting
Severe gum disease can result in tooth shifting, as inflammation and bone loss around the teeth cause them to loosen. This can cause the formation of gaps between teeth as they gradually change position.
Improper Swallowing Reflex
An incorrect swallowing reflex, where the tongue presses against the front teeth instead of the roof of the mouth, can also contribute to gap formation. Over time, this repeated pressure pushes the front teeth forward, creating noticeable spaces between them.
Bad Oral Habits
Bad oral habits such as thumb sucking, lip sucking, and tongue thrusting can apply consistent pressure to the front teeth, causing them to shift forward and create gaps. These behaviors can interfere with the natural alignment of teeth and contribute to the development of diastemas.
Loss of Baby Teeth
In children, temporary gaps may appear when primary teeth, or baby teeth, are lost. However, these spaces usually close as permanent teeth come in. This is a normal part of childhood dental development and typically does not require treatment.
Treatments for Increased Gaps in Teeth
- Braces: Traditional braces gradually shift teeth into proper alignment, effectively closing gaps for a straighter, more even smile.
- Dental Bonding: A quick, affordable solution that uses tooth-colored resin to fill small gaps and improve the appearance of your smile.
- Veneers: Custom-made porcelain shells that cover the front of teeth, seamlessly concealing gaps and enhancing aesthetics.
- Dental Implants: A permanent solution that replaces missing teeth, preventing gaps caused by tooth loss and restoring functionality.
- Dental Bridges: A fixed prosthetic that fills gaps from missing teeth by anchoring an artificial tooth to adjacent natural teeth or implants.
- Invisalign: Clear, removable aligners that discreetly and comfortably close gaps while straightening teeth over time.
How Can You Prevent Teeth Gaps From Increasing?
While some factors causing teeth gaps are beyond your control, there are effective ways to minimize their progression:
Maintain Excellent Oral Hygiene
Brush twice daily with fluoride toothpaste and floss regularly to prevent gum disease, a leading cause of shifting teeth. Regular dental cleanings help keep gums healthy and teeth in place.
Correct Oral Habits
Avoid thumb-sucking in kids and work with a professional to correct tongue-thrusting habits. Wear a nightguard if you grind your teeth.
Replace Missing Teeth Promptly
Fill gaps left by missing teeth with dental solutions like implants or bridges to prevent shifting.
Seek Treatment for Gum Disease Early
At the first signs of gum inflammation, visit your dentist to prevent bone loss and subsequent tooth shifting.
Conclusion
Teeth gaps, or diastemas, can increase due to a variety of factors, including gum disease, misaligned teeth, bad oral habits, or the natural aging process.
While many people are concerned about the aesthetic impact of gaps, it’s important to recognize their potential implications for oral health. Early diagnosis and treatment are key to preventing gaps from widening and maintaining a healthy smile

FAQs
Why do teeth gaps increase with age?
As we age, our teeth naturally shift due to a process called mesial drift, where teeth gradually move toward the center of the mouth. This can lead to existing gaps becoming wider over time.
Can front teeth gaps be fixed without braces?
Yes, front teeth gaps can be fixed without braces using treatments like dental bonding, veneers, or Invisalign. These options can close gaps effectively and improve the appearance of your smile.
Is diastema genetic?
Yes, genetic factors can play a role in the size and spacing of teeth, and gaps between teeth can often run in families.
Can diastemas close on their own over time?
In some cases, small gaps may close naturally as the permanent teeth erupt or the jaw grows, but larger gaps usually require treatment to prevent further widening.
