What Causes Black Triangles

What Causes Black Triangles?

Black triangles, also known as open gingival embrasures, are small, triangular gaps between teeth that can be unsightly and cause self-consciousness. They are often caused by receding gum tissue, which can happen due to a number of factors.


Here are some of the most common causes of black triangles:


1. Gum disease

Gum disease is the top cause of black triangles. It is an infection of the gums that can damage the tissues that support your teeth. This damage can cause your gums to recede, exposing the roots of your teeth and creating black triangles.

2. Hard Brushing, or Brushing with Hard Bristles

Brushing your teeth roughly can damage your gums and cause them to recede. This is especially true if you use a hard-bristled toothbrush.

3. Age

As we age, our gums naturally recede. This is because the bone that supports our teeth starts to shrink, and the gums can no longer cover the roots of our teeth.

4. Tooth wear

Over time, our teeth wear down. This can create spaces between our teeth, which can then become filled with food and debris. This can make black triangles more noticeable.

5. Orthodontic treatment

In some cases, orthodontic treatment can cause black triangles to form. This is because the movement of teeth can cause the gums to recede.

6. Genetics


Some people are more prone to developing black triangles than others. This is because the shape of their teeth and gums can make them more likely to recede.


Other causes of black triangles include:


* Smoking
* Dry mouth
* Bruxism (grinding of teeth)
* Diabetes
* Certain medications
* Symptoms of black triangles

In most cases, black triangles are not a cause for concern. However, they can be a symptom of an underlying dental problem, such as gum disease. If you notice black triangles, it is important to see your dentist to rule out any underlying problems.


Treatment for black triangles


If you have black triangles, there are a number of treatments that can be effective. The best treatment for you will depend on the cause of your black triangles and the severity of the problem.


Here are some of the most common treatments for black triangles:

1. Orthodontic treatment

If your black triangles are caused by crowded teeth, orthodontic treatment can be used to move your teeth into a more aligned position, which can close the gaps between your teeth. Braces or clear aligners, such as Invisalign, are commonly used for this purpose.

2. Bonding

Bonding is a cosmetic procedure that involves using a tooth-colored resin to fill in the gaps between your teeth. Bonding is a quick and relatively painless procedure, and it can be a good option for small black triangles.

3. Veneers

Veneers are thin, shell-like covers that are bonded to the front surface of your teeth. Veneers can be used to cover black triangles as well as other cosmetic imperfections, such as chipped or stained teeth.

4. Gum grafting

Gum grafting is a surgical procedure that involves grafting tissue from another part of your mouth to the area where your gums have receded. Gum grafting can be a good option for larger black triangles or for cases where the gums are very thin.

5. Interproximal reduction (IPR)


IPR is a procedure in which a small amount of enamel is removed from the sides of your teeth to create more space between them. This can be effective in closing small black triangles.




Black triangles can be a frustrating cosmetic problem. However, there are a number of treatments that can be effective in closing them. If you are concerned about black triangles, it is important to see your dentist to discuss your treatment options.
