Are Black Triangles Normal?

Black triangles, clinically known as open gingival embrasures, are triangular spaces that appear between two teeth at the gum line. There are a few reasons that black triangles can form; some of these reasons are normal and some are less so. The general cause of black triangles is gum recession, which can occur because of aging or simply because of the nature of the gum tissue. Gum recession can also arise because of gum disease or infection and can be exacerbated by smoking, improper brushing, or hormonal changes, like those experienced in pregnancy. Black triangles can also appear because of the shape of the teeth or as a result of certain orthodontic treatments. While black triangles are largely considered a cosmetic concern, they can also increase the risk of gum disease and tooth decay by creating easy places for bacteria and food debris to collect and accumulate. Though black triangles are a normal occurrence, they should be closely monitored or treated to reduce the risk of gum disease and tooth decay.

People with certain tooth shapes are more prone to black triangles, though the majority of people have some type of triangular gap on the root end of the teeth, at the gum line. The three main tooth shapes are rectangular, oval, and triangular. Rectangular teeth that are parallel from top to bottom don’t tend to create gaps near the gum line. Oval teeth often create rounded gaps toward the bottom of the teeth, though the tops of the teeth may touch without gaps. Triangular teeth are just what they sound like, sloping outward so that the bottoms of the teeth touch but the tops don’t. These teeth are the most likely to allow the formation of black triangles, which may appear larger or more significant when gum recession or gum disease are present.

The two most common ways of addressing black triangles are with interproximal reduction, commonly referred to as IPR, and cosmetic bonding. In an IPR treatment, the dentist files away a small amount of dental tissue, allowing the teeth to fit together more closely. Dentists might also use treatment approaches that serve to rehabilitate the gum tissue, reducing the gum recession that can cause black triangles to form. If the black triangles are significantly large, dentists can also use cosmetic bonding techniques, filling the gaps with tooth-colored resin. Sometimes, black triangles can develop after orthodontic treatment; these smaller gaps should not be a cause for concern and could even help patients keep their teeth clean by facilitating easy, thorough flossing.

If you have black triangles that have developed because of gum recession caused by gum disease, treating the gum disease can halt the progression of gum recession and manage the black triangles. Proper oral hygiene can also help slow gum recession, which can be caused or exacerbated by too-aggressive brushing. Talk to your dentist about effective brushing and flossing techniques, and make sure to include regular dental checkups in your oral hygiene routine. Early intervention can often reverse the effects of gum disease and help maintain the health, integrity, and appearance of the teeth, reducing or preventing black triangles when possible.
