Actually, with oral piercings, that 'white stuff' is a fact of life just like the crust on external piercings. It definitely doesn't mean an infection is present unless the tongue is !Very tender, !Dark red, or !If the secretion is tinged green. The white ooze in oral piercings is totally normal. You know how if you cut your lip by accident, rather than a scab (as with an external injury - and that's what a piercing is, an injury)there is a white film. Now, your tongue doesn't really scab exactly, but it does secrete a sticky whitish-yellowish fluid that looks, well, kinda like snot. Take some Motrin, swish with warm salt water (boil the water, let it cool, ad 1/2 tsp per 8oz water) twice daily. Don't eat spicy stuff,don't smoke, don't drink alcohol, don't put other people's bodyparts in your mouth, try to avoid dairy. Throat lozenges are really soothing, both because of their numbing effect and the suck motion. Be gentle, and patient with your new piercings. Tongues heal very fast, although it's REALLY uncomfortable at first, it will be over soon.
I'm no doctor, clearly, but I've worked in the same studio for seven years now. I pierce tongues pretty much on the daily.
