Daiso interdental brush!

My teeth are thin, so I use the thinnest SSS size... it's 0.7mm. It's L-shaped, so it's easy to hold and use, and I like that it's long. You can get 8 packs for 2,000 won at Daiso! It's so good for removing food debris between your teeth after meals... Once you try this, you'll feel like you have to take it with you when you travel... I actually find this easier to use than dental floss... Everyone should give it a try.
