Know About Black Triangles Between

Who doesn’t like a beautiful smile?

A pearly white smile boosts confidence and self estimate for any individual. There are many dental problems that can affect your beautiful smile, and black triangle teeth are one of them. It is not only creating an unpleasant appearance but also inviting other dental problems like gum diseases or tooth decay.

In this article, we are listing the essential information you should know about black triangle teeth; what causes it, treatment and so on.

What is Black Triangle Teeth?

Black triangle teeth, also known as ‘open gingival embrasures,’ are the spaces (shown in a triangle shape) between the teeth and the gum line. Regrettably, they can draw unwanted attention when a person is smiling. More specifically, they form as we age, through hard brushing techniques, and with the other gum/periodontal disease.

Moreover, the triangle gaps can be served as food traps, which can easily harvest plaque, food, and stains. The accumulation of debris can potentially lead to gum disease or tooth decay. These triangles sometimes even affect your speech or result in ‘spitting while talking.

Causes of the black triangle

There can be numerous causes of black triangle teeth, but some of the most common causes include:

Dental hygiene habits

As the gum tissue is sensitive, hard brushing techniques will create problems. If you are brushing your teeth too aggressively, your gums will be damaged over time; consequently, a black triangle occurs.

Gum recession

Gum tissues bind your teeth together. Sometimes, factors such as age, smoking, and periodontal (gum) disease can cause gums to shrink or pull away from the teeth.

As a result, the teeth’ roots are exposed to a space that makes them vulnerable to bacteria, plaque, and cavities.

Bone loss

A loss of bone near a tooth’s base can potentially cause gum disease, osteoporosis, and other conditions. And, when the bone is lost, it affects the gum tissue (which may also recede). Hence, the formation of black triangles takes place.

How to Fix Black Triangles Between Teeth

There are a number of options available to get rid of the black triangles between teeth. Your dentist will suggest the best possible treatment depending on the cause and severity of the gaps. However, here we have listed the standard treatment used to fix the gaps.

Gentle, proper dental hygiene

Brushing your teeth regularly with proper techniques will help you to keep your overall dental health in good shape. When you want to keep your gums healthy, you should floss daily. If the black triangles between your teeth are minimum with healthy gums, improving your dental hygiene habits may enable your gums to return to normal.

Composite resin

Some people choose to have their dentist fill the gaps with composite resin bonding. Based on your individual needs, your dentist might advise using a pink resin or a tooth-colored resin to fill the triangles between your teeth and give you a beautiful smile.

This is a nonsurgical process, but it is time-consuming for sure. It takes months to complete because the resin is applied in very thin layers to make it look natural, and your gums can adjust to the smaller space. Besides, tooth-colored composite veneers also are applied to improve the appearance of the teeth.


A cement ceramic or porcelain veneer is one of the preferred treatments to fill in gaps and create a more even smile. Most of the time, applying veneers includes modifying your natural tooth’s surface so the veneer and tooth form a sturdy bond. Also, veneers last up to 20 years and are commonly used in many dental treatments.


If black triangles developed between your teeth as a result of a procedure or process that affected your teeth, you might be able to fill the gaps by moving teeth collectively with braces.

Besides, orthodontic treatment takes time, but the aesthetic results will be worth your time and the cost of your pay.

In addition, with the advancement of medical science, there’s a new method to treat the black triangles.

Hyaluronic acid treatment

In some cases, your dentist can suggest regenerating gum tissue with injections of hyaluronic acid. As it is less painful and quickly recovers, it is preferred by the patients.

In a nutshell, which treatment to choose highly depends on the condition of your oral health and the severity of the black triangles? Consult your dentist, who will guide you through the best possible treatment to correct those gaps. Early diagnosis will help you to resolve any dental problem easily and quickly. If you are experiencing any oral problems, consult your dentists as early as possible to treat the issue correctly and prevent further complications.
