Diastema or Teeth Gap: Causes, Treatments & Prevention

Summary

Diastema, commonly known as a teeth gap, is a condition where noticeable spaces exist between teeth, often the upper front ones. It can result from genetics, mismatched jaw and teeth sizes, missing teeth, or habits like thumb sucking. While some embrace it, others seek treatment due to cosmetic or functional concerns. 

Treatment options include orthodontics (braces, Invisalign), cosmetic solutions (bonding, veneers, crowns), and surgical procedures like frenectomy. 

Preventive measures include good oral hygiene, correcting harmful habits, and regular dental check-ups. Consulting a dentist helps determine the best solution, ensuring optimal oral health and a confident smile.

Introduction

Diastema, often referred to as a gap between teeth, is a common dental condition seen in both children and adults. While some people appreciate it as a distinct trait, others opt for treatment due to cosmetic or functional concerns.

The condition arises due to factors like genetics, mismatched jaw and teeth sizes, missing teeth, or habits like thumb sucking and tongue thrusting. If left untreated, diastema can lead to speech difficulties, food impaction, and bite misalignment.

Treatment options vary based on severity and cause. Orthodontic treatments like braces and Invisalign help shift teeth into alignment, while cosmetic solutions such as bonding, veneers, and crowns offer quick aesthetic fixes. Dental implants and bridges address gaps caused by missing teeth, and procedures like frenectomy remove excess tissue, causing spacing.

What is Diastema?

Diastema is a condition where there is a noticeable gap between teeth, most often the upper front teeth.

Diastema can occur due to several factors, such as genetics, dental habits, or structural issues in the mouth. While diastema is frequently seen in children as part of their natural dental development, it may persist into adulthood if not corrected.

The condition is usually harmless but can sometimes lead to dental health problems, such as speech issues, difficulty in chewing or an increased risk of food particles getting stuck between teeth.

Depending on its cause and severity, diastema can be treated with orthodontic or cosmetic dental procedures.

Different types of Diastema

Diastema refers to a noticeable gap between teeth, commonly seen in both children and adults. It is particularly frequent in children and may close naturally as their permanent teeth grow in. Below are the different types of diastema:

• Midline Diastema (Median Diastema): This is a gap between the two upper front teeth (central incisors). It is one of the most common forms of diastema and may be caused by genetics, excessive tissue (frenum), or missing lateral incisors.
• Lip-Tie Diastema: A tight or thick labial frenum can prevent the front teeth from coming together, leading to a persistent gap. This condition may require a frenectomy (surgical removal of the tissue) to close the gap.
• Gaps between Molars: Spacing issues can also occur between the back teeth, such as molars and premolars, due to factors like jaw size, tooth loss, or improper eruption patterns.
• Severe Diastema: In some cases, diastema can be significantly large due to missing teeth, gum disease, or an improper bite. Severe cases often require orthodontic treatment, such as braces, aligners, or dental bonding, to close the gaps.

What causes Diastema?

The following are some of the causes of diastema:

• Genetics and hereditary factors – Some people are naturally predisposed to teeth gaps.
• A mismatch between teeth and jaw size – Small teeth in a large jaw can cause gaps.
• Missing teeth or small teeth – This can result in adjacent teeth shifting and creating gaps.
• Overgrowth of the labial frenulum – Excess tissue between the upper front teeth pushes them apart.
• Thumb sucking or tongue thrusting habits – Can exert pressure on teeth, causing gaps.
• Periodontal disease – This leads to bone loss and tooth movement, increasing spacing.
• Improper swallowing reflex – Pushing the tongue against teeth while swallowing can create gaps.

Potential problems associated with teeth gap

Here are some of the problems associated with teeth gap:

• Aesthetic concerns – May affect self-confidence.
• Speech difficulties – Large gaps can impact pronunciation.
• Food impaction – Increases risk of gum problems and cavities.
• Bite issues – This can lead to misalignment and uneven wear on teeth.

Diastema treatment

Diastema, or gaps between teeth, can be treated through various dental procedures depending on the extent of the problem and the underlying cause.

While minor gaps may close naturally, others require orthodontic, cosmetic, or surgical intervention. Below are the most effective treatment options for diastema closure.

Orthodontic treatments

For individuals with a diastema caused by misaligned teeth or jaw structure, orthodontic solutions are highly effective.

• Braces (Traditional and Clear Aligners): Traditional metal braces gradually push the teeth into proper alignment with time, effectively closing gaps. If you are looking for a more discreet option, clear aligners like Invisalign are available, providing a nearly invisible way to straighten teeth. These aligners are removable and comfortable, making them a preferred choice for adults and teens.
  
• Retainers: Retainers are useful for minor gaps and post-orthodontic treatment maintenance. They help to retain the teeth in the correct position, preventing gaps from reappearing after braces or aligner treatment.
  

Cosmetic dentistry solutions

For those looking for a quick and aesthetic solution to diastema, cosmetic dentistry provides several options:

• Dental bonding: In this procedure, tooth-coloured resin is applied and shaped to close small gaps instantly. It is cost-effective and non-invasive.
• Veneers: Thin porcelain or composite shells cover the front surface of teeth, effectively closing gaps and enhancing appearance.

• Diastema closure with crowns: If the gap is too large for bonding or veneers, dental crowns can reshape and close the spaces between teeth. Crowns also improve the teeth’s strength and functionality.

Dental implants or bridges

If the diastema is caused by missing teeth, dental implants or bridges are the best solution.

• Dental Implants: A titanium post is surgically placed in the jawbone, and a custom-designed crown is attached to replace the missing tooth, closing the gap permanently.

• Dental Bridges: These are highly helpful to replace one or more missing teeth by anchoring artificial teeth between natural ones.

Frenectomy

A frenectomy is a surgical procedure to remove an overgrown labial frenulum, the tissue that connects the upper lip to the gums. If a thick or extended frenulum is causing a midline diastema, removing it allows the teeth to shift naturally or with orthodontic treatment. This is often done in children if the gap does not close as they grow.

Composite fillings

For small diastema, composite fillings can be used alone or combined with other treatments like bonding or orthodontics.

These tooth-coloured fillings help reshape teeth and close minor gaps without extensive dental work.

Each treatment option is tailored based on the patient’s needs, severity of diastema, and overall oral health. Consulting a dentist is the best way to determine the most suitable treatment plan.

Factors to consider before choosing the right treatment for Diastema closure

Here are some of the factors to consider:

• Severity and size of the gap – Small gaps may be closed with bonding or veneers, while larger gaps may require braces, crowns, or implants.
• Underlying causes – Identify whether the diastema is due to genetics, gum disease, missing teeth, or an oversized frenum before selecting a treatment.
• Age of the patient – In children, some gaps close naturally as permanent teeth emerge, while adults may need dental intervention.
• Budget and treatment preferences – Options range from cost-effective solutions like bonding to long-term investments like orthodontics or implants.

How to prevent a teeth gap (Diastema)?

Here are some of the fantastic ways to prevent diastema:

• Encourage good oral hygiene practices – Brush, floss, and use a mouthwash to maintain healthy teeth and gums.
• Correct harmful oral habits early – Discourage thumb sucking, tongue thrusting, or improper swallowing patterns in children.
• Routine dental check-ups – Regular visits help detect early signs of spacing issues and prevent worsening conditions.
• Address gum disease or tooth alignment issues promptly – Treating periodontal problems and misaligned teeth can prevent diastema formation.

When to see a dentist?

While some cases of diastema are harmless, certain situations require professional evaluation and treatment. You should see a dentist if you experience:

• Persistent gap widening or tooth movement – If the gap is increasing over time, it may indicate underlying issues such as gum disease or shifting teeth.
• Difficulty chewing or speech issues – Large gaps between teeth can affect bite alignment, making it harder to chew properly or causing speech difficulties like a lisp.
• Concerns about appearance – If the gap affects your confidence or smile aesthetics, cosmetic solutions like veneers, bonding, or orthodontics can help.
• Oral health issues – Diastema can sometimes lead to food trapping, plaque buildup, or gum problems, increasing the risk of cavities and gum disease.

Diastema treatment cost in Malaysia

The diastema closure price in Malaysia varies depending on the treatment chosen. Braces or clear aligners typically cost between RM 6,000 – and RM 15,000, while cosmetic treatments like bonding or veneers can range from RM 500 – RM 3,000 per tooth.
