In hip hop culture, the term grill refers to a cosmetic dental apparatus worn over the teeth. Grills are made of metal (often silver, gold, or platinum) and are sometimes inlaid with precious stones (traditionally princess-cut diamonds). Grills can cost anywhere from $50 to several thousand dollars, depending on the materials used and the number of teeth covered. Grills can be purchased online or at specialty shops. […]

According to the American Dental Association in June 2006, no studies have shown whether the long-term wearing of grills is safe. Grills made from base metals could cause irritation or allergic reactions. Additionally, school districts in Alabama, Georgia, and Texas have banned grills.
