Daith piercing. A Daith piercing (pronounced DÃ¤TH) is an ear piercing that passes through the ear's innermost cartilage fold, the crus of the helix. In most areas this piercing is pronounced day-th which can be compared to the word faith, which is nonstandard. The standard pronunciation is doth like goth.
The heavier your belly piercing jewelry and the more deeply you're pierced, the less likely your new belly button piercing will be to migrate out or reject entirely. This is true even for standard-placement belly button piercings; heavier-gauge jewelry is less likely to migrate out than finer-gauge jewelry (e.g. 16g and smaller). Your piercer may offer you the choice between a bent barbell, a captive ring, or a circular barbell for your belly button piercing starter jewelry.
