question: Hi! My 11 month old son has a strange \"growth\" in the gums over one of his baby teeth.  It nearly covers the entire tooth.  While attenpting to remove it with a tissue, a white \"plug\" came out of it.  It was not liquid, but gelatinous in consistancy.  Could this be a parasite, or just solidified pus?  What would you recommend we do.  Thx!
