Upper Lip Frenulum Piercing

The upper lip frenulum piercing passes through the webbing underneath the centre of the upper lip. The piercing heals very quickly and is relatively painless. It looks best on someone whose lips retract when they smile — showing off the piercing as well as teeth and drawing attention to the smile.
This piercing is prone to rejection and many people find that they just "fall out" after about a year. This process is relatively harmless.
This piercing is usually performed using an 18ga to 14ga captive bead ring (or sometimes a circular barbell), sized so that the bead rests just below the gumline, between the front teeth. It can of course be performed using other jewelry or sizes that don't show.

This piercing can cause gum erosion and lead to tooth decay due to abrading the enamel.
