I had my wisdom tooth deteriorating and it started making a smell (I go to the dentist tomorrow). I kept brushing etc.. but it wouldn't go away and I broke off pieces of the tooth and out came this tiny thing that I remember reading about once but can't figure out how to search the word is right on the tip of my tongue basically it's like a nucleus or whatever of germs like a germ factory like a tiny little ball of germs does anyone know what I'm talking about. I wanna say it starts with the letter p it was about 1/20th of an inch
