Black discoloration on the grooves of teeth may be caused by untreated dental stains or tartar buildup, or it could result from food debris and bacteria trapped in the tooth's grooves that haven't been properly cleaned, leading to tooth decay. If cavities are left untreated, plaque bacteria can accumulate over time in the grooves, often resulting in black discoloration on the surface of the tooth grooves.
