Are Black Triangles Normal?
Black triangles are the small space that can develop between two teeth at the gum line. They are very common and can occur in patients of any age. Most of the time, black triangles are not anything to be worried about and are simply a cosmetic concern but occasionally, they can be a symptom of an underlying condition such as periodontal disease, bone loss, or other medical issues.
Causes of Black Triangles in Teeth
As we age, our gum tissue naturally thins and recedes. When those black triangles form, it can be a hindrance on your oral health depending on the size of the space. Large black triangles can create a food trap and lead to an increased buildup of plaque and bacteria which can quickly lead to tooth decay.
Patients who are undergoing orthodontic treatment may notice the appearance of black triangles as their teeth straighten. Teeth that are tapered at the root will often have a little bit of space between teeth along the gum line which may not have been obvious before if the teeth were crowded and overlapping. As the teeth begin to straighten and become properly aligned, black triangles can appear. This is often a simple fix with interproximal reduction which simply means that your doctor will use a thin dental file to knock off some of the tooth structure between teeth so that the orthodontic appliance can work to pull the teeth closer together. This typically will close any black triangles that appear during orthodontic treatment.
There are a few treatment options available for patients who are bothered by black triangles and their smile. Your dentist can place dental bonding to build up to service in the open space or they can even apply dental veneers which will give you an entire new tooth shape and close the space.
Other options include gum grafting and gum rejuvenation with filler injections of hyaluronic acid. A gum graft is a more invasive surgery than filler injections but it will last four years with good oral care whereas filler injections will need to be redone every six months or so.
Depending on the cause of your black triangles, your dentist may advise one treatment above another. If you have underlying periodontal disease, it is very important to have that addressed and taken care of before things worsen and you start to experience bone loss and tooth loss. A simple deep cleaning may be all you need to get your teeth and gums healthy!
Black triangles will not go away on their own and they were only get larger overtime. If you have black triangles in your teeth, discuss them with your dentist even if they do not bother you cosmetically. After any treatment, it is important to improve your oral hygiene practices and continue seeing your dentist at least twice a year unless otherwise advised to visit more frequently.
