It is not normal for your tongue to be numb after piercing. Try exercising the tongue by rolling it and moving it around, if the feeling doesn't come back go see a doctor, the piercer could have hit a nerve in your tongue. I had my tongue pierced but no I didn't experience numbness. If the feeling doesn't come back soon I would go see a doctor, because you have nerves and veins under there that may have been affected. Not to sound like a "Mom" but these problems are why tongue piercing are illegal now and hard to come by. I had to take mine out because it was making a hole on the roof of my mouth from rubbing. So just be careful!! ----------------Tongue piercing is not illegal everywhere, nor is it a majorly dangerous practice. The reason you get problems with rubbing holes inside your mouth has more to do with having the wrong jewelry. BE CAUTIOUS of those piercing outside of an established studio and make sure that YOU, yourself keep your piercing clean. Yes there are nerves in your tongue that can be damaged but it's rare.
