Tongue Rings, Tongue piercing
The tongue piercing, consists of a barbell through the center of the tongue. To avoid damaging the nervous system, tongue rings are generally placed vertically at the center of the tongue, in front of the "webbing" or lingual frenulum which attaches the tongue to the bottom of the mouth. Alternately, pairs of "snake bite" piercings could be done on either side of center, giving the appearance of fangs. Tongues are often very easy to stretch, so enlarging the hole is also an option after healing. Like with any stretching, this should be done gradually - no faster than one size in 2 months.
