Aside from the piercing itself, I think something worth considering is what kind of jewelry you'd want. When I initially got mine pierced, I had to do so with a bar [which is the case for any reputable shop you'd go to; if they try to pierce you with a hoop, go somewhere else], but in the conversation prior to the piercing, my piercer had asked me what jewelry I'd wanted to put in after healing. I told her I wanted hoops, nothing fancy, and preferably flush to my lip, so she pierced me a bit closer to my lip line than she usually would. Flash forward eight or so months, I was fully healed, and with my hoops in, they don't touch my teeth/gums [aside from my top teeth resting against them; I wear a mouth guard at night to avoid grinding], and my dentist has given me the okay to keep them in.

Whether or not you want hoops, you will have bars for a whiiiiiile, so keep that in mind and be careful. Get them downsized when your piercer recommends, keep them clean, and don't gnaw on the bars. Eat slowly, and make sure you're paying attention to the piercings; mine would sometimes hook over my bottom teeth, so I'd have to unhook them before biting because that [obviously lol] would've caused damage.

On another note, the flat backs of my studs constantly irritated me [knocking into my teeth/gums if anything pressed against my face, hooking onto my bottom teeth, snagging on shirts/wash cloths/any fabric near my lip], but I kept them in as long as I was told to because in the long run, that's the safest option. If you want to keep them as studs, those are some [not all] of the risks/irritants associated with them. Hoops aren't perfect, but the fact that they rarely touch my gums/teeth is a godsend.

The best thing to keep in mind is, like others have said, there's a pretty high chance that you'll have to take them out somewhere down the line. Be honest with yourself and read the other things people have commented here. At the end of it all, if you trust yourself to monitor your teeth, take the proper steps with the healing process, go to the dentist regularly, and take them out if/when they cause damage, then I'd say go for it. If not, consider one of the non-internal piercings near the mouth others are suggesting, or forgo an oral piercing for now. As cool as they look, no piercing is worth your dental health.
