Can Black Triangles be Fixed

145 Black Triangles – Can Black Triangles be Fixed? (1 of 5)

Some patients have visible black triangles between their teeth. When this occurs, patients are often curious what causes the issue, treatment options, and how it impacts their oral health. Gingival embrasure is another term used to describe these black triangles. The triangular spaces appear when there is inadequate gum tissue between the teeth.

Gum recession is the most common cause for black triangles. Issues such as periodontal disease, smoking, and aging can cause receding gums. When the gums are not strong and healthy, they can start to pull away from the teeth, exposing the roots to bacteria and cavities. It is also possible for the gums to be damaged due to aggressive brushing or the use of a firm toothbrush.

The shape of the natural tooth plays an important role in the development of black triangles. Teeth or incisors which are narrow at the gum line and broader at the bottom biting surface can make a patient more likely to have visible triangles. It is also possible for triangles to develop following the movement of teeth after an orthodontic treatment such as braces. When the patient has especially large black triangles after treatment, they may require additional treatment.

Another possible cause for black triangles is when there is bone loss near the base of the tooth. Bone loss may be the result of gum disease, osteoporosis, or other oral health issues.

The shape of the tooth can indeed affect the likelihood of a patient having black triangles. Teeth which are rectangular have straight, symmetrical edges. This allows the teeth to fit together without gaps, meaning there are no gingival embrasures. Oval teeth have space at the bottom from their rounded edges, but the tops of the teeth fit together. This makes it unlikely for black triangles to be present. Teeth which are triangular in shape have a wider edge at the biting surface and are narrower towards the top. This ultimately results in black triangles.

Black triangles may indicate there is an underlying oral health problem which needs to be treated. Patients with new or recently developed gaps between the teeth should follow up with the dentist. The dentist will likely perform an examination to determine the underlying cause. Before the dental professional can treat the cosmetic aspect of black triangles, they must first treat any underlying issues. Below are treatments which are often used to reduce or eliminate the appearance of black triangles.

Oral Hygiene
Patients should avoid using too much force when they are brushing and flossing as it can cause damage and result in the formation of black triangles. When the gaps are minor and patients have otherwise healthy gums, the damage can often be reversed through the use of gentle pressure when brushing.

It is also important for patients to use the proper technique to avoid damaging the teeth and gums. When flossing, the floss should slowly be slid against the teeth to remove any remaining food and debris. Patients should use a gentle circular motion when brushing. It is also critical to use a soft bristled toothbrush as medium to firm bristles can damage the enamel and gums.

Orthodontic Treatment
Some patients find that they have black triangles after they have braces or another type of orthodontic treatment. In some cases, additional treatment may be required to eliminate the spaces. While black triangles can seem like a minor cosmetic issue, it can cause serious oral health issues when it remains untreated.

Dental Resin and Veneers
In cases where the tooth’s shape is causing the appearance of black triangles, the dentist may opt to use a dental resin or veneers for treatment. Dental resin works by filling the gaps between the teeth and giving the tooth a more rectangular shape. It is also very affordable. Teeth which have other cosmetic issues, such as chips and discoloration may benefit from the use of veneers. Veneers are more expensive, however, are an excellent solution which can last for many years.
