This is just a note about information thats been in the news related to
tattoos and piercings. There are many health risks which may or may not
show up right away as a result of putting metals and dyes into your
body. Materials and dyes used in tattooing and body piercing are
unregulated. Most dyes used in tattooing are not approved for cosmetic
purposes and were produced for industrial uses such as car paint.
Some alternative doctors have ways to test for heavy metal toxicity now
and I know a few people who have this toxicity.
One way this happens is from dental fillings (metal one's). So with
tongue piercing, when you have two dissimilar metals in your mouth you
form a battery, and through electrogalvanism you will actually have
current floating in your mouth.

This article has some more info if you're interested.
