What Causes Black Triangles?
You may have noticed small gaps between your teeth and gumline that are in the shape of small triangles. Dentists refer to these as open gingival embrasures and they may not have always been as noticeable.
There are multiple reasons why you have these open gingival embrasures, but they are not always a sign of problematic dental conditions. They are most visible on your front teeth and the spaces are open due to a combination of a lack of gum tissue and teeth tapering towards the gums, in most cases. As we get older, our gums tend to recede but when you also have gum disease, your gums are more likely to shrink. Tooth infections and improper brushing techniques can also cause your gums to recede closer to the gumline and further away from your teeth.
Should you be concerned about black triangles?
Black triangles between your teeth can diminish your confidence and distract from your smile. Dentists are less concerned with the aesthetics of black triangles and more with the space they create for bacteria and plaque to grow. Small particles of food can get trapped in those small openings and leave you at great risk for tooth decay and even gum disease. If your open gingival embrasures are not bothering you, be sure to talk to the dentist about them anyway. The dentist can give you tips to brush and floss the areas thoroughly and can keep an eye on those areas during exams to ensure they do not threaten your overall oral health.
Can black triangles be prevented?
You may not be able to prevent black triangles in your mouth all together with proper brushing and flossing techniques. If your family has teeth that are naturally broader towards the bottom and more narrow to the top or thinner gum tissue, then you may be more likely to have black triangles develop over time.
Simply taking the time to brush your teeth twice a day with a soft bristled toothbrush, floss regularly, and keep dental exams every six months, you will be able to address any gum disease or tooth infections before they create larger black triangles. If you notice your gums are red or swollen in an area or your gums bleed after you brush, you may want to make an appointment with the dentist to ensure you are not experiencing an infection or gingivitis.
How can we treat black triangles?
Depending on the root cause of your open gingival embrasures, they may worsen and get larger over time. Be sure to talk to the dentist about your concerns and the dentist can review some of the following treatments to address your black triangles:
* Improved at home oral care. If your black triangles are a result of gum disease, the dentist can stop the gum disease from progressing and work with you on your at home care of your teeth and gums.
* Periodontal treatment. If your gum disease has progressed from the beginning stages of gingivitis to periodontitis, the dentist may suggest treatment from a periodontist.
* Dental bonding. The dentist may be able to increase the size of your teeth with a dental bonding composite that matches your tooth color.
* Gum rejuvenation.
* Interproximal reduction and orthodontic treatments
