As toothpastes consist of several abrasive substances (like, Aluminium hydroxide), this layer of silver sulphide can be removed by rubbing the article with toothpaste. This reaction leaves the silver metal all shiny. This particular cleaning process can be improved by using hot water and sodium bicarbonate.

Answer:
tooth paste contains abrasive paticles that that can polish off tarnish. these same particles can scratch silver up as well. in particular you avoid using tooth paste on sterling silver, high polished silver or anything that silver plated.
