Lip piercing
Lip piercing is the practice of piercing one's lip with a stud (barbell) or ring. This practice has some historical precedent, but is known by most as an activity of the youth.
A decorative item is worn in the piercing; commonly a single-ball barbell (also referred to as a 'post'), captive bead ring, spike or, nowadays, an inert plug. Traditional labrets were often clay disks. The modern labret, with a steel ball or spike visible, is a piercing that particularly suits men with round faces and/or beards.
The labret piercing is a relatively straightforward procedure; the lip is held away from the mouth with a clamp, whilst a hollow needle (14g/1.6mm as standard size) is pushed through, usually from inside-out. The jewellery (which should be a little larger than normal, to accommodate for swelling) is then inserted into the end of the needle, which is then removed and the jewellery fastened. Oral piercings heal very quickly and resist infection, but stick to sensible after-care, such as watered-down Listerine and/or salt-water mouthwashes, daily. An unstretched piercing closes up very quickly - in a matter of hours - so if you have a job interview, take the jewellery with you and pop it back in afterwards. Alternatively, clear jewellery is available so as to keep the piercing open without the notice ability of a stud or ring. These are known as 'retainers'. It should be noted that retainers are not suitable to be worn during the initial healing process.
The labret was a traditional piercing among the American North-West Coast Indians, where it was related to status:
The word is from the Latin labrum, lip. It is not French, and should be pronounced "la-bret" not "la-bray."Anthropology
When a mask was being made to represent someone of high status, naturally enough, that mask had a labret. Word Origin
