Black triangles occur when there is a loss of gum between the teeth. This can occur when there is a loss of bone due to disease, crooked teeth, or poor hygiene, among other reasons. These little "triangles" of "black" space (pictured below) tend to catch more food and plaque in the middle, along with being unaesthetic!  When closing a black triangle space, we can't just stuff a filling in the middle and call it a day. Front teeth require specific anatomy and gentle curves not just for esthetics, but for ease of flossing and cleansing. The purpose of this anatomy makes it harder for plaque to catch in between and, thus, prevent bacterial growth which can lead to further gum loss. To remedy this, we place fillings between the teeth with a device called a Bioclear Matrix (below).  Sample photo provided from https://www.aegisdentalnetwork.com/id/2011/05/the-bioclear-matrix-and-peg-lateral-treatment This plastic Bioclear matrix template allows us to bond a filling that has all the right shapes and curves to give us an aesthetic AND cleansible restoration.  Note how the unesthetic black triangle spaces are now filled with aesthetic restorations that have all the right shapes and sizes. The teeth and gums are easily cleansible and will significantly reduce the amount of plaque trapping between the teeth. This patient's smile now looks many years younger!
