i don't think that's a good idea, it might irritate the new piercing. i got my tongue pierced a little over a year ago, what i did was suck on ice chips, which kept the swelling down.. not greatly but it did help & it also helped a lot with the pain. i also would rinse my mouth often with listerine that contained ANTISEPTIC. the antiseptic has some numbing properties and it helped me a lot. other than that try some ibuprofen as well. hope i helped you.
Don't put any sort of cream near it as it will irritate it. If you're thinking of doing this because it's sore, drink a frozen coke or suck on some ice. It worked for me. :)
use clove oil. it works better and fasteer than orajel
ask the pharmacist if you could use orajel.
