Assuming you have it done at a good professional piercing studio, none really. But I know the "dental community" (these are my dentist's words) hates them, because people can break their teeth on them, or they can hurt the gums.
However, that would generally only happen if you weren't wearing the proper type of or size or jewelry, if it were placed improperly, etc. On many people, the back of a labret (middle, and kind of low) piercing will rub against their front bottom teeth's gums, making them recede. I have a middle and side lip piercing that I wear with either studs or rings, and the jewelry NEVER touches my teeth when it's at rest, when I'm talking, or when I'm eating, so I'm fine. I also have a scrumper (aka smiley, aka upper frenulum) piercing, and that doesn't hurt my teeth either, despite my dentist's claims.
That would be the professional body piercers concern during your tongue piercing.
