High Quality Content by WIKIPEDIA articles! In hip hop culture, a grill (also front or golds) is a type of jewelry worn over the teeth. Grills are made of metal and are generally removable. They began to be worn by hip hop artists in the early 1980s, but they became widely popular during the mid-2000s due to the rise of Dirty South rap. Though grills are fitted to the tooth impression of the wearer, whether they are safe for long-term wear is unknown.
