What is plaque?
It's the stuff that grows on your teeth and gives you gum disease and decay. It's normally white though, so you can't see it, but we've been having fun with some new dye that makes it go pink (or blue if it has been there for ages!)
This dye can be really handy so you can see what's happening with your brushing and flossing. We really like to help our patients look after their teeth so they don't get so many dental problems.
I suspect everyone would have really clean teeth if plaque was pink naturally!
