interdental brush with lid

I use interdental brushes; does everyone else use them? I didn't used to, but as I get older, my teeth seem to be shifting a bit. I wonder if it's just me, haha. So, food particles keep getting stuck in my teeth after meals, so I find myself using these regularly. My dentist also recommended using interdental brushes. As you can see in the picture, they come with a cap, so they're great for carrying around.
