Well if you already have the silver stuff on your tooth the only way to get it out is if your tooth falls out or if the stuff scrapes off...or you could just lower the amount of sugar intake you have.
Hope I could help!!

when you are visualizing, you are no longer focused in reality.
Some parts of out body itch because of many reason they might be
•Dry Skin
•Bug Bites(bedbug/lice/scabies)
•Itchy skin condition
•Allergic reaction
•Skin Cancer
•Warning of a disease (Diabetes/HIVetc)
(There are other reasons too like:
•Reaction to plants and marine life(poison ivy/other plants you might be allergic to/water/pond)
•Nerve Problem)
Anyways it ming not be something to be afraid of because sometimes my skin too itches without any reason. It can be that we have a dry skin. But if you want to you can go to a dermatologist. Just remember that it is okay to have some rashes and itches. Stay safe
