Tooth Gem
A tooth gem is a gemstone glued onto the enamel of a person's tooth. It can be a single gemstone, or multiple arranged into shapes. They are semi-permanent, lasting from several months to several years. Over time the bond between the tooth and an improperly applied gem may weaken, creating a gap which cannot be cleaned, allowing bacteria to accumulate and can eventually lead to tooth decay. Tooth gems cannot be placed on veneers as they are too smooth. See also * Grill (jewellery) References Types of jewellery Dental modification {{Fashion-stub ...

Gemstone
A gemstone (also called a fine gem, jewel, precious stone, or semiprecious stone) is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments. However, certain rocks (such as lapis lazuli, opal, and obsidian) and occasionally organic materials that are not minerals (such as amber, jet, and pearl) are also used for jewelry and are therefore often considered to be gemstones as well. Most gemstones are hard, but some soft minerals are used in jewelry because of their luster or other physical properties that have aesthetic value. Rarity and notoriety are other characteristics that lend value to gemstones. Apart from jewelry, from earliest antiquity engraved gems and hardstone carvings, such as cups, were major luxury art forms. A gem expert is a gemologist, a gem maker is called a lapidarist or gemcutter; a diamond cutter is called a diamantaire.

Veneer (dentistry)
In dentistry, a veneer is a layer of material placed over a tooth. Veneers can improve the aesthetics of a smile and protect the tooth's surface from damage. There are two main types of material used to fabricate a veneer: composite and dental porcelain. A composite veneer may be directly placed (built-up in the mouth), or indirectly fabricated by a dental technician in a dental lab, and later bonded to the tooth, typically using a resin cement. They are typically used for treatment of adolescent patients who will require a more permanent design once they are fully grown. The lifespan of a composite veneer is approximately four years. In contrast, a porcelain veneer may only be indirectly fabricated. A full veneer crown is described as "a restoration that covers all the coronal tooth surfaces (mesial, distal, facial, lingual and occlusal)". Laminate veneer, on the other hand, is a thin layer that covers only the surface of the tooth and is generally used for aesthetic purposes. ...

Grill (jewellery)
In hip hop culture, a grill (most commonly referred to as grills or grillz), also known as fronts or golds, is a type of dental jewelry worn over the teeth. Grills are made of metal and are generally removable. They began to be worn by hip-hop artists in New York City in the early 1980s, and upgraded during the 1990s in Oakland. They became even more widely popular during the mid-2000s due to the rise of Southern hip hop rap and the more mainstream pop culture status hip hop attained. Characteristics and wearer demographics Grills are made of several types of metal (often silver, gold or platinum) that are sometimes inlaid with precious stones; they are generally removable, though some may be permanently attached to the teeth.Schepp, David"Gold Teeth Are a Gold Mine."''BBC News'' (August 3, 2001).
