interdental brush

I only use this one.

As you get older, the gaps between your teeth widen. Whenever I eat, something gets stuck in them no matter what. It’s gotten to the point where I’m afraid to eat out... because I have to poke around every time. Haha. It’s become a habit now, so if I don’t do it, I feel uncomfortable. It’s an absolute must-have for me. I always stock up so I never run out.

It's easy to carry around, affordable, and not very irritating, so I think it's good to use.
