Grillz are a popular fashion accessory worn by many hip hop artists and fans alike. However, there are several synonyms for this term that can be used interchangeably. Some of these include "grills," "fronts," "gold teeth," and "diamond teeth." Each of these terms refers to the same type of jewelry, typically made of gold or silver and often encrusted with diamonds or other precious stones. While grillz have been a staple in hip hop culture for years, they have recently gained mainstream popularity and can be found in many jewelry stores and online shops.
