The smiley piercing goes through the frenulum (the small web of skin that connects the gum to the upper lip), and can only be seen when the wearer is smiling (hence the name). Due to its discrete placement, low pain level and fast healing time, the smiley piercing is fast becoming one of the most popular piercings of our time. Ball closure rings and horseshoes are the most commonly worn jewellery styles in the smiley piercing, but they can also be fitted with smooth hinged rings for an even more subtle look.
