I don't think it can, but it is quite possible. If you eat something sugary that you aren't supposed to eat, that could go straight to your blood stream from the hole in your tongue. It can also be dangerous in other ways. Someone I know had an infection around the piercing, and almost lost his tongue. I would just be extra careful with your tongue. It is a very important part of your body...as is anything else on your body.
I don't have a white ring under my tongue.
There is no "lock on a tongue ring" and it's not a ring it's a barbell.
If you have a tongue ring, it makes it hard to make out. the ring always gets in the way.
Google search for "18 gauge tongue ring"!
The same way you did before, except now you have a tongue ring.
No.
No one understands your ungrammatical/incomplete sentence. Also, there really is no such thing as a tongue ring, though there theoretically could be. I believe you mean a tongue STUD.
Yeah. Some tongue ring balls are pretty big and may look tacky on lip rings.
Yes
Well the only way to put anything into a tongue is to use a needle to pierce the tongue first then put a barbell into the newly pierced hole. (Please quit calling it a tongue ring, it's a barbell and not a ring).
No, its not. Go see your piercer.
