Angel Dust is also known as PCP. It is known as a Hallucinogen, but has the effects of a stimulant, an anesthetic, or a narcotic pain-killer, depending on the amount taken.
They are generally made of porcelain or gold. A dental inlay is a prosthesis made of a solid substance and cemented into a cavity inside a tooth. A dental onlay is similar to an inlay, except that onlays lay on or over a cusp, which is a portion of the toothâs surface.
This means the inlay/onlay doesn't stress the tooth in the way that placing a composite filling directly into the cavity would. Like composite fillings, the material still has a tendency to pick up some stain at the margins. They will discolour and wear more over time than their porcelain and gold counterparts.
