When I was at the dentist today, I asked them about where to get their dental tools (scrapper). I was sure I could get them on Amazon or WalMart. My dentist said that they keep old tools that they no longer need in the back. She went back and got me three different kinds. She said her tools were a lot better quality than WalMart. I will use these to clean my suppressors if they ever come in. Next time you are at your dentist, ask if they have some old ones.
