Does toothpaste ruin sterling silver?
Toothpaste contains abrasive particles that can polish off tarnish. These same particles can scratch silver up as well. In particular, you should avoid using toothpaste on sterling silver, highly-polished silver, or anything that is silver-plated. These items are very soft and can be easily damaged by the toothpaste.
