Do you have black triangles?

How to get rid of black triangles?

When the idea of a perfect smile comes to mind, most people think of fixing crooked teeth and whitening as examples of fixing their dental imperfections. However, a common problem not known about is the black spaces at their gum lines also known as “Black Triangles” are the third most identified aesthetic complaint.

What are black triangles?

Black triangles are a common dental issue that occur between the teeth near the gum-line causing an unattractive gap to appear. These gaps can be caused by several factors including gum recession, misaligned teeth, or an improper bite. In addition to being a cosmetic issue it can also cause other dental problems such as trapped food particles, plaque, tartar, and bacteria if left untreated.

Another type of gap is known as a diastema. This can naturally occurs between teeth and is usually seen in the front teeth. In such cases, there may be nothing wrong with the teeth itself, however, many people do not like its appearance and it can affect their confidence.

If you notice gaps forming between your teeth, I would recommend that you discuss this concern with us, as we a uniquely able to specifically treat black triangles using Bioclear Method https://www.bioclearmatrix.com/. Read on to learn more.

What causes black triangles?

There are several reasons why you develop black triangles or the gap between your teeth along your gum line.

Black triangles can appear between your teeth for several reasons and some may have health consequences which stem from your gums. Black triangles are usually caused by gum recession. Our gums naturally recede as we age, but gum disease, dental infections, and vigorous brushing can increase it. Black triangles (Open Gingival Embrasures) are triangle-shaped gaps between your teeth, which is obvious when you smile. Roughly 67 percent of adults have them.

1. The shape of the tooth:

Teeth come in different shapes and sizes. Your incisors are the front teeth in your mouth. Black gaps can form between your teeth if your pores are narrower at the gum line than at the biting surface. Conditions like gum disease can cause your gums to recede or thin. Your gums stop filling the natural spaces between your teeth, leaving empty spaces that look like black triangles.

2. Gum recession:

Normal healthy gums are usually pink and fill in the small gaps that surround your teeth.

Heavy handed toothbrushing, age, smoking and gum disease can cause the gums to shrink away from the teeth. This exposes the roots leaving them vulnerable to sensitivity, food getting trapped and cavities.

3. Aggressive brushing:

Gum tissues are sensitive. Some people have thinner gums than others. If you scrub your gums aggressively or you floss too hard, you can injure the soft tissue between your teeth and damage your gums over time. It creates gaps between your teeth like gum disease Our Dentists and Oral Health Therapists can help you learn to brush correctly and prevent black triangles from forming.

4. Bone loss:

Active gum infection also known as periodontitis can result in the bone dissolving just under the gums. This is caused by a constant immune response to the bacteria that never leaves and hides deep under the gums. Once the bone is lost, the gums also shrink away from the teeth, leading to the formation of black triangles. As the bone beneath them begins to disappear, your gums will also begin to recede. Problems like osteoporosis and severe gum disease can cause bone loss. Speak to our dental team if you think your dark triangles may be due to bone loss.

5. Orthodontic treatment:

If you have had orthodontic care, small gaps may form between your teeth as they move into their new positions. Braces and other orthodontic treatments are meant to
secure or move your teeth to a better location. But these changes can leave gaps between your teeth that may require further treatment.

A 2018 study found that the likelihood of adults with braces developing black triangles between their upper and lower incisor teeth was 22 percent and 36 percent, respectively.

6. Triangular tooth shape:

Some people have rectangular teeth, where the width of the tooth at the gum line isn’t much different than the width tooth edge. This results in broad contacts between the teeth which means that only a small space needs to be filled by the gum tissues.

Some people have narrower teeth at the gum line so that the tooth has a more triangular shape. Triangular teeth are more likely to develop these gaps as there is more space between the contacts and the gum tissue.

7. Thin fragile tissue:

The thickness of gum tissue varies from person to person. Thin tissues are more prone to irreversible damage. So if there is gum disease, elective dental treatment such as a crown, a dental implant, or gum surgery, the gums may not return to their previous fullness afterwards.

If you suspect you may have this condition, be sure to have it treated. It will restore confidence in your smile and appearance and it will also reduce risks of further dental issues.

Should you be concerned about black triangles?

Most patients dislike the black triangle due to the way they look. As dentists, we dislike black triangles because they can trap food and plaque, increasing your risk of tooth decay and gum disease.
If you are unhappy with your black triangles book a consultation with our dental team and we can show you what can be done to help get rid of the black triangles.

Can black triangles be prevented?

Black triangles cannot necessarily be prevented, and some patients tend to have them because they have very triangular-shaped teeth or thin gum tissue.
However, you can reduce and avoid gum recession by taking care of your oral health and with a good daily oral care routine this can reduce contributing factors such as gum disease and dental infections.
This includes gentle and thorough brushing for two minutes twice a day and flossing once a day. Dental Hygiene. You should also watch out for any symptoms of gum disease such as red, swollen gums; loose teeth; and bleeding while brushing. Book an appointment with us if you have any concerns.

Eliminating Black Triangles can dramatically improve your smile increasing your confidence and boosting your dental health.

Indirect porcelain crowns and veneers

Traditional treatment options for black triangles may include dental bonding, porcelain veneers, gum grafts or orthodontic treatment, depending on the underlying cause.

Dentists have been using this treatment option to yield good results however it comes at a very high financial and biological cost. Tooth structure is often shaved down and removed in order to be covered with porcelain. The outcome looks good afterwards, however, it would be more ideal to be able to keep the original tooth structure.

Therefore, at Bella Dental we offer a unique technique to help get rid of black triangles:


Rejuvenate your smile with the better-looking, longer-lasting, less-invasive approach to dental restorations

Bioclear is a modern approach to cosmetic and restorative dentistry. It’s both a methodology and a set of tools and materials that are designed to improve your smile.

The entire process—known as the Bioclear Method—is founded on principles of structural engineering and modern materials science. Procedures are quick, easy, and minimally invasive. The results last much longer than traditional bonding, conserve far more of the underlying tooth structure, and look more natural. It is our aim to raise your expectations of what is possible.

The BIOCLEAR Method is an approach to cosmetic and restorative dentistry that is used instead of traditional fillings, bonding, or veneers. BIOCLEAR lasts longer than traditional composites, porcelain, or amalgams. Furthermore it has a more natural and consistent appearance.

What is the BIOCLEAR method?

BIOCLEAR is a revolutionary technique characterized by composite resin injection over-moulding. https://www.bioclearmatrix.com/ BIOCLEAR Matrix System

The result produced is superior aesthetics and it also more durable. Precious tooth structure is preserved as the material is bonded to the existing teeth.

BIOCLEAR https://www.bioclearmatrix.com/ uses specialised shape barriers which helps to sculpt natural contours to fill the negative spaces in black triangles. With results in stronger teeth that support restoration to eliminate the unsightly gaps.

Dr Geoffrey Wan is fully certified to provide treatments using the BIOCLEAR Matrix technique, an ideal solution to fix black triangles between teeth. he is also one of the first dentists to offer the BIOCLEAR procedure in Australia. BIOCLEAR Certified Provider

What can Bioclear do?

  • Fill in the triangle-shaped gaps (black triangles) created by receding gumlines
  • Fix chips or breaks without replacements or crowns, leaving as much of the underlying tooth structure as possible.
  • Repair small or misshapen teeth to create an even smile.
  • Cover stained or discolored teeth to create a long lasting, natural looking smile

What are the benefits of the BIOCLEAR method?

  • The BIOCLEAR method offers several benefits compared to traditional restorative dentistry including:

    1. Faster and less invasive procedure: The BIOCLEAR method uses minimally invasive techniques to restore damaged or decayed teeth, reducing the need for extensive removal of healthy tooth structure.
    2. Improved aesthetics: By using clear composite resin materials that blends seamlessly with the natural tooth, a more natural-looking and aesthetically pleasing result is achieved.
    3. Durability: Advanced materials and techniques are used to create a strong durable bond between the restoration and the tooth, this increases the longevity of the restoration.
    4. Minimal tooth reduction: The BIOCLEAR method often requires less removal of healthy tooth structure as compared to traditional restorative techniques, preserving more of the natural tooth.
    5. Reduced tooth sensitivity: It helps to reduce post operative tooth sensitivity by preserving more of the natural tooth structure and creating a tighter bond between the restoration and the tooth.
    6. Reduced cost of future dental work: Due to the durability and minimal reduction of natural tooth structure, savings in future dental costs can be achieved.

Why choose the BIOCLEAR?

It’s stronger and longer lasting

The typical longevity of a composite restoration—like certain cavity fillings—might be two to five years. Traditional composites are applied at room temperature, in successive layers. This not only creates noticeable edges at the gumline, but also weakens the structural integrity of the restoration. After that, they need to be touched up or replaced. There was clearly room for improvement.

Bioclear uses a heated composite made by 3M that is flowed in, rather than layered. Essentially, the material that will form the new tooth structure is combined with a warmed, viscous material that allows it to be flowed into the Bioclear Matrix, creating a single, monolithic fill that is cured (hardened) with light. The result is harder and more structurally sound than layered composite alone. Bioclear restorations typically last fifteen to twenty years or more.

It conserves more of your natural tooth structure

Traditional restorations end at the gumline, often creating ridgelines that over time can irritate and inflame the gums. Bioclear restorations start below the gumline (thanks once again to the Bioclear Matrix).

Then there are the preparations! Preparations refer to the process of readying a tooth (or teeth) for restoration. Even today, dentists will remove all existing enamel in order to prep for porcelain veneers. Bioclear preparations only call for removing unhealthy tooth structure: it inherently conserves more of the healthy, original tooth. And care is taken to remove accumulated biofilm—that’s the organic material that collects even on healthy teeth—ensuring that the heated composite adheres directly to your enamel.

It looks better and more natural

This is due in part to the anatomically shaped Bioclear Matrices, but it also has a lot to do with the final polish.

Even the latest composites may look grainy or have a matte finish compared to the slightly translucent, reflective quality of your natural teeth. Once applied and hardened and dry, these composites are polished with a small sanding bit on a drill. Bioclear applies what we affectionately call the “Rock Star Polish.”

The polishing is done wet, using water and a special slurry, keeping the temperature down and thus maintaining the integrity of the restoration. And the polishing mix itself is made of a safe, food-grade pumice.

Case study using the BIOCLEAR method

A case shown below is a patient who is in her 40’s who just finished her braces. She has experienced recession and noticed the spaces opening up between her teeth over the years. She considered veneers to close the spaces but did not want to shave down her perfectly healthy teeth for that outcome. She did her research wanted to fill the spaces using the BIOCLEAR method.

The photos show the black triangles that had appeared after the braces were removed. The front 6 teeth were restored using the BIOCLEAR protocols. Post-operative x-rays were taken to demonstrate the absence of overhangs and tooth contours were preserved for easy hygiene upkeep and more beneficial for gum health. This patient now loves her smile.

It uses unique matrices and composite materials to create strong and aesthetically pleasing restorations, improving the appearance and functionality of the teeth.

Bioclear differs from traditional dental bonding and veneers in its technique and materials used. Traditional dental bonding involves applying composite resin directly to the tooth and shaping it by hand. On the other hand, Bioclear uses specialised matrices to create a custom mould around the tooth, allowing for precise and predictable restoration.

Compared to veneers, which require significant enamel removal, Bioclear is a more conservative option, preserving more natural tooth structure while achieving excellent aesthetic results.

No, the Bioclear procedure is typically painless. Local anaesthesia may be used to numb the treatment area to ensure patient comfort during the procedure. Most patients report minimal discomfort afterwards, which can be managed with over-the-counter pain relievers if needed.

The longevity of Bioclear restorations depends on several factors, including the patient’s oral hygiene practises and lifestyle habits. With proper care and regular dental check-ups, Bioclear restorations can last for many years.
