Hello, this is Gangnam Leon Dental😊
Did you know that there is a triangular shape between teeth?
It is not just any triangle, but a black one.
This is called a black triangle.
By checking whether there is a black triangle,
we can tell the condition of gum health.
Today, let’s look at the causes of black triangles,
as well as improvement methods and management.

What is a black triangle?
A black triangle refers to a triangular black space
that appears between the gums and the teeth
due to gum recession.
In fact, even if there is no particular abnormality,
anyone can have a slight black triangle.
What matters is that if it is not managed,
or as time passes, this black triangle
gradually becomes larger.

Causes of black triangles
The representative causes of black triangles
caused by gum recession are as follows.
✔ Gum disease ✔ Aging ✔ Smoking ✔ Incorrect brushing
① Gum disease (periodontal disease)
This is the most representative cause of gum recession.
When gum disease develops due to plaque/tartar
and gingival inflammation,
bone around the gums disappears and the gums recede,
causing black triangles.
② Aging
As people get older, the gums can naturally
gradually sink down.
③ Smoking
Smoking harms oral health
and increases the risk of gum disease,
worsening black triangles.
④ Improper brushing habits
The habit of brushing with too much force,
thinking you are cleaning your teeth well,
can also damage the gums.

In addition, gaps between teeth can also occur
due to wearing prosthetic appliances.
Or black triangles may appear after scaling.
In many cases, this happens because the swelling
caused by tartar goes down and the area becomes visible,
not because scaling itself created it.
Improving black triangles
Appropriate treatment is performed depending on
the cause of the black triangle.
If gum bone has been lost due to gum disease,
periodontal treatment should be performed
to prevent the progression of gum inflammation.
If you later want cosmetic improvement,
it can be improved with the following methods.
| Newtis front tooth resin | The empty space is filled using resin similar to the color of the teeth. It is a relatively simple and affordable improvement method. |
|---|
| Newtis Lami | A thin Newtis Lami veneer is attached to improve the shape and color as desired. It offers both excellent aesthetics and durability. |
| Orthodontic treatment | If it is judged that improvement is possible by moving the tooth alignment, orthodontic treatment is also an option. |

Managing black triangles
When a black triangle appears,
in order to protect gum health,
it is necessary not only to brush your teeth,
but also to remove food debris left between the teeth
and on the gums, which is easy to miss.
Therefore, using dental floss/interdental brushes,
it is good to prevent cavities and gum disease,
and to receive scaling regularly
to remove plaque and tartar, which are major causes
of gum inflammation.
✔ Dental floss/interdental brush
Choose the size and thickness that fit the size of the black triangle
and remove debris.
Depending on how you use it or your condition,
bleeding may sometimes occur while using it,
but if gum bleeding continues and is accompanied by pain,
it may be a symptom caused by inflammation,
so be sure to visit a dental clinic for an examination.
✔ Scaling
It is good to receive scaling at least once a year,
and preferably once every 6 months.

If you are concerned about black triangles,
first visit a dental clinic to check whether it is gum recession
caused by gum inflammation, and receive appropriate treatment
accordingly, along with a convenient consultation for aesthetic improvement.
