The connection between teeth gaps and oral health
Can those gaps between your teeth impact your oral health? You might be surprised! While some people appreciate the unique charm and personality these gaps add to their smiles, others desire a more uniform and properly aligned set of teeth. Teeth gaps can appear for a variety of reasons and may hinder hygiene, disrupt alignment and affect self-esteem.
Teeth gaps
Let’s start by getting a clear understanding of what we mean by “teeth gaps.” Teeth gaps, medically known as diastema, refer to spaces or gaps between two teeth. These spaces can manifest anywhere in the mouth but are particularly noticeable when they occur between the front incisors.
Diastema is characterised by spaces wider than 0.5 mm between teeth. This criterion helps distinguish natural gaps, often present in childhood, from larger spaces that might necessitate intervention for both aesthetic and functional concerns.
Different types of diastema
Not all teeth gaps are the same. Understanding the different types can provide insight into their causes and potential treatment options.

Midline diastema: Occurs between the upper central incisors, creating a gap in the middle of the upper front teeth. Often noticeable and may be a cosmetic concern.
Maxillary lateral diastema: Involves a gap between the upper lateral incisors. Can result from variations in tooth size or position.
Median diastema: These are gaps between multiple front teeth, usually in the upper jaw. Can involve a combination of midline and maxillary lateral diastemas.
Mandibular diastema: Similar to midline diastema but occurs in the lower front teeth. May also be related to tooth size discrepancies or misalignment.
Generalised spacing: Involves gaps between multiple teeth throughout the mouth. Can be associated with factors like tooth size discrepancies, genetics or developmental issues.
Common causes of teeth gaps
Here are some common reasons for the development of gaps between teeth:
Natural development in children: Before the eruption of permanent teeth, it’s common for children to have gaps between their primary teeth. These gaps often close naturally as the adult teeth come in.
Size discrepancy: Disproportionate sizes of teeth or jaw can result in gaps. For instance, if the teeth are too small for the jawbone, or if the jawbone is too large for the teeth set it accommodates, gaps may occur.
Missing teeth: Gaps can occur when there are missing teeth, creating space for adjacent teeth to shift. This can happen in cases where a permanent tooth doesn’t replace a lost baby tooth.
Periodontal disease: Advanced gum disease, or periodontal disease, can weaken the attachment of teeth to the bone. This weakening can cause teeth to shift from their original positions, leading to gaps.
Genetic predisposition: Some individuals may be genetically predisposed to diastema, meaning that the trait runs in their family.
Abnormal habits: Certain habits, particularly in childhood, can contribute to gaps:
- Thumb sucking can exert pressure on front teeth, pushing them outward.
- Tongue thrusting, where the tongue pushes against the front teeth during swallowing, can also contribute to gaps.
- Prolonged use of pacifiers or bottle-feeding can impact tooth alignment.
Large labial frenulum: The labial frenulum is the tissue connecting the upper lip to the gum. If this tissue is oversized, it can create a gap between the upper central incisors.
Poor dental hygiene: Inadequate or inconsistent dental hygiene practices can lead to periodontal disease, a precursor to diastema.
Tooth extraction: In some cases, the removal of a tooth, particularly without proper replacement, can result in neighbouring teeth shifting and creating gaps.
Trauma or injury: Accidents or injuries to the teeth may cause them to shift or move, creating gaps.
Persistence into adulthood
While gaps between baby teeth are often considered a temporary part of dental development, diastema can persist into adulthood. Factors such as the size and shape of adult teeth, gum structure and individual oral habits contribute to the continuation of these spaces beyond the developmental years.
Oral health consequences of teeth gaps
Teeth gaps can have many different oral health consequences, impacting your overall well-being. While not all cases of diastema lead to health issues, it’s essential to be aware of potential consequences. Here are some oral health implications associated with teeth gaps:
Risk of tooth decay: Gaps can trap food particles, leading to increased bacterial activity and a higher risk of tooth decay. Difficult-to-reach areas may be more prone to cavity development.
Chewing and digestion problems: Larger gaps can impact the efficiency of chewing and biting. Difficulty breaking down food properly may affect digestion and overall nutritional intake.
Speech difficulties: Diastema, especially when significant, may affect speech patterns. Articulating certain sounds, such as “s” and “f,” can be challenging, potentially causing speech impediments. Gaps between teeth can also result in airflow disruptions, causing whistling sounds during speech.
Poor aesthetic appearance: While primarily a cosmetic concern, the appearance of teeth gaps can impact an individual’s self-esteem and confidence. Negative perceptions of their smile may contribute to psychological stress and social anxiety.
Gum problems: These gaps create areas that are prone to the accumulation of plaque and bacteria. When oral hygiene practices are insufficient or compromised due to the presence of diastema, the buildup of plaque along the gumline can lead to the onset of gingivitis—an inflammation and redness of the gums. Untreated gingivitis can progress to periodontitis, a severe gum disease that damages the supporting structures of the teeth, including the bone.
Temporomandibular Joint (TMJ) issues: The irregular spacing between teeth can disrupt the natural alignment of the jaw, contributing to imbalances in the temporomandibular joint. This misalignment may lead to different TMJ problems, causing jaw pain, headaches and discomfort while chewing. The strain on the jaw joint resulting from the improper distribution of forces can further intensify TMJ-related symptoms.
Misalignment and bite issues: Diastema can be associated with misalignments, such as rotated or crooked teeth. Irregular tooth alignment may contribute to malocclusions, affecting the harmonious fit between upper and lower teeth, known as occlusion.
Increased tooth sensitivity: The exposed tooth surfaces resulting from spacing can lead to increased sensitivity. This heightened sensitivity may occur when teeth are exposed to temperature changes, sweet or acidic foods, causing discomfort.
Maintaining oral health with teeth gaps
Importance of regular dental check-ups
Regular dental check-ups are crucial for maintaining optimal oral health, especially in individuals with teeth gaps. Dentists can closely monitor the condition of the teeth and gums, identify potential issues in their early stages and provide appropriate guidance and treatment. Routine check-ups also facilitate professional cleanings, effectively removing plaque and tartar buildup in and around the gaps. This, in turn, reduces the risk of gum disease and other oral health problems.
Oral hygiene tips for individuals with teeth gaps
Taking proactive steps in oral hygiene is essential for individuals with teeth gaps. Here are some useful tips to keep in mind:
- Proper brushing techniques: Brushing twice a day with a soft-bristle toothbrush and fluoride toothpaste is essential. Pay close attention to cleaning the gaps and all tooth surfaces. Utilise gentle, circular motions to ensure thorough cleaning without causing harm to the gums.
- Flossing and interdental cleaning: Regular flossing is crucial for removing plaque and food particles from between teeth and gaps. Use dental floss, interdental brushes or water flossers to clean these areas effectively.
- Use of mouthwash: Incorporate an antimicrobial mouthwash into your oral hygiene regimen to reduce bacteria and refresh your breath. Choose alcohol-free mouthwashes recommended by your dentist.

Dental cosmetic solutions for closing teeth gaps
Dental bonding
Dental bonding is a cosmetic solution that involves applying a tooth-coloured resin material to the teeth to close gaps. The resin is sculpted and bonded to the teeth, creating a more even and cohesive smile. This quick and cost-effective procedure is a popular choice for minor teeth gaps.
Dental veneers
Dental veneers are thin, custom-made shells, typically made of porcelain or composite resin, that are bonded to the front surface of teeth. They can effectively close gaps and improve the appearance of teeth. Veneers provide a durable, natural-looking solution for those seeking a more comprehensive smile transformation.
Orthodontic treatments
Orthodontic treatments can effectively close gaps and improve overall tooth alignment. Two common options are:
- Traditional braces: Metal or ceramic brackets and wires are used to gradually shift the teeth into the desired position. Traditional braces are a versatile and robust option, especially effective for addressing a wide range of teeth gaps, including major cases.
- Clear aligners: Custom-made clear aligners are a popular choice for closing gaps discreetly. These transparent, removable aligners gradually move the teeth into alignment, providing a more aesthetically appealing option for individuals concerned about the appearance of braces.
Restorative options for extensive teeth gaps
In cases where the gaps are more significant or there are missing teeth, restorative options can be considered:
- Dental implants: Dental implants are a permanent solution for replacing missing teeth. They involve surgically placing an artificial tooth root (typically made of titanium) in the jawbone, which serves as a stable foundation for a replacement tooth to fill the gap.
- Crowns and bridges: Dental crowns can be used to cap individual teeth adjacent to the gap, while a dental bridge can span the gap by anchoring to adjacent teeth, effectively “bridging” the space or replacing the missing tooth.

Closing the gap for better health and confidence
Addressing teeth gaps goes beyond aesthetics – it’s about improving your smile’s functionality and overall well-being. Whether you go for restorative, orthodontic or other options, the right treatment can close the gap, enhance your oral health and raise your confidence.
For personalised advice, consult your dentist. They can evaluate your oral condition, guide you to the most effective solution and help you enjoy the benefits of a more functional, confident smile. Closing the gap isn’t just a cosmetic choice; it’s a step toward a better quality of life.
