forever
you ask a tattoo artist and sometimes they fade away
Generally, as long as the frog.
3-5 days
It will last around 2-5 days normally :-)
Not substantiated is the rumor that she has a Rolling Stones logo (Tongue) tattoo.
If there is a regular tattoo/piercing shop, they'll pierce your tongue.
Tattoo ink can last for life when done properly with quality ink. There are many factors that determine the length of time the ink will look nice.
That depends upon how severely the tongue has been burned, but in my experience, if I have burned my tongue I recover within a day at the most.
Some last months some last forever it matters how deep the artist goes
claires acceseries, piercing shop, tattoo parlors etc
Well considering the nature of the tongue and the fact that any intelligent tattooist will not tattoo a tongue just out of shear common sense, there should be no consequences. However should you find an idiot to tattoo your tongue be aware that most pigments can be toxic if ingested, not to mention you run a good chance of choking to death from the localized swelling. Tongues don't like being messed with that way. Tattoos on mucous tissue are very very invasive and can damage the tissue resulting in secondary infection.
