Black triangles between teeth

Open gingival embrasures or black triangle teeth can easily ruin an individual’s self-confidence and smile aesthetics. It creates dark, unappealing gaps, which could be a nightmare for anyone. Not only is it unpleasant to look at, but it also negatively impacts your oral health. Those gaps can trap food particles and create plaque, which will increase the risk of gum disease.

If you’re going through this issue, the good news is that you have a few options to deal with it. Before we discuss what causes black triangles between teeth or how they can be treated, let’s discover what those black triangles are.

What Are Those Black Triangles between Teeth?

Black triangles are those gaps between the teeth that are formed when the gum papilla (the gum tissue) is insufficient to fill the space. They could be formed for several reasons. Sometimes they could be natural, due to the shape of your teeth, or they could occur due to changes after orthodontic treatment. Other times, they can be a result of disease or infections.

Causes of Black Triangles between Teeth

Black triangles can form between your teeth for several reasons. To stay safe, consult a dentist as soon as possible if you notice black triangular spaces between your teeth.

Gum Recession

The foundation of your oral health is the gums. They grip and protect your teeth. However, habits such as smoking, neglecting oral hygiene, and natural factors like age can cause deterioration, causing gum recession gaps.. This leads to exposing the roots and leaving your teeth vulnerable to bacteria, plaque, and cavities.

Bone Loss

Certain diseases, such as osteoporosis, can cause bone loss. Once the bone is lost from the base of the teeth, the gum tissue loses its support. Which creates one of those black triangles we’ve been talking about.

Dental Hygiene Habits

Always remember to be gentle with brushing. If you brush too hard, your gum tissues may be damaged. Also, flossing is very important for your gum and teeth health.

How to Prevent Black Triangle Teeth?

To prevent black triangle teeth, ensure a good oral care routine. Brush your teeth twice a day, floss consistently to remove any plaque, and do not poke your gums with a toothpicks.

Brush Twice a Day

Go for a soft-bristle brush and a fluoride toothpaste. Buy a toothpaste that is designed for your specific needs, such as sensitivity, cavities, or gum health. If you have doubts when buying a toothpaste, then simply consult your dentist for the best recommendation.

Use a Tongue Scraper

Some of the toothbrushes already have a tongue scraper. Either you could use that or get a separate one. But make sure to remove the bacteria from your tongue.

Floss On a Daily Basis

Rinse your mouth, then tear off an 18-inch dental floss string. Slide it between your teeth, make a ‘c’ shape, and rub it down against the tooth surface to remove food particles. Keep a firm grip and repeat the process for all teeth before discarding it.

Use a Mouthwash after Brushing and Flossing

After you’re done with teeth cleaning, use a mouthwash after 30 minutes. Go for a mouthwash that is non-alcoholic. Some people use mouthwash every day, while others use it on selective days. Your oral needs will define the best way to use a mouthwash. This will add an extra layer of protection, fight infection-causing bacteria, and give you fresh breath.

Bioclear is another technique to close the tooth gaps. Dentists place a thin mold around the teeth and fill it with warm resin. Once the resin settles down, it gives a strong, natural, and stain-resistant finish. The Bioclear method is great for keeping your natural tooth structure intact.
