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.
Nothing if you have any sense. And if you must have a lip ring and nothing else will do, it is best to got to a professional piercer who knows how to do it safely. If you persist on getting it pierced than you ought to know that they use a needle to pierce it and I think they use a lime to get rid of the pain. But, Yes if you had any sense than you wouldn't get it done, especially your tongue. You tongue can swell but if your lucky you won't have to get your tonge removed.
Generally the tongue will prevent that from happening however it's still wise to rinse with a good mouth wash after you have removed the barbell and consumed anything, just to be on the safe side.
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.
