Unfortunately, problems with your teeth often have a negative effect on how you feel about your smile, and black triangles in between your teeth, a condition known as open gingival embrasures, fall under that category. Black triangles sometimes create an unpleasant look that can make you feel less confident when you interact with other people, but they can also result in other dental problems like gum disease or tooth decay.
Black triangles are typically found in front teeth, but not exclusively. The gaps that form between your teeth and gumline are caused by a lack of gum tissue, sometimes due to recession, but also by gum disease. As you age, your gums naturally recede, but black triangles can be aggravated by overly aggressive brushing.
While black triangles cannot necessarily be prevented, you can minimize gum recession and avoid contributing factors—such as gum disease and tooth infection—by following a daily routine of good dental care at home. Brush twice a day for at least two minutes each time, floss at least once a day, and use an antimicrobial or fluoride mouth rinse.
Black triangles have several common causes:
What Causes Black Triangles?
1. Dental hygiene habits, especially pressing hard while brushing your teeth, can damage sensitive gum tissue over time and contribute to black triangles.
2. Gum recession, brought on by factors such as age, smoking and tobacco use, and periodontitis (gum disease), can cause your gums to shrink and pull away from your teeth. You need strong, healthy gum tissue to hold your teeth in their proper place in your mouth.
What are Treatments for Black Triangles?
3. Exposed roots make your teeth vulnerable to bacteria-filled plaque, cavities, and the development of black triangles.
4. Bone loss near the base of a tooth can potentially cause gum disease, osteoporosis, and other conditions. When bone is lost, gum tissue recedes, which leads to the formation of black triangles.
Depending on the cause and severity of your problem, your dentist will suggest the best treatment options for you:
1. Composite resin bonding is an inexpensive way to fix small black triangles. Your dentist will apply a resin that matches your tooth color to build up the teeth and fill the gaps. Bonding is a nonsurgical process that can be time-consuming. Your dentist may decide to apply several thin layers to fill the space.
2. Custom-made veneers are a popular treatment to fill gaps in black triangles and create a more even, pleasing smile. Your dentist will modify the natural surface of your tooth to create room so that the thin ceramic or porcelain veneer can be cemented in place for a natural, attractive look.
3. Braces can help fill gaps between teeth caused by black triangles. Orthodontic treatment takes time, several months at least, but the aesthetic results you see will be worth it.
4. Injections of hyaluronic acid are a newer method for treating black triangles. Patients have come to prefer this method because it is less painful and recovery is relatively quick.
The treatment you choose depends on the condition of your oral health and the severity of your black triangles. Your dentist will advise you on the approach that is best for you.
