치간칫솔이 편한가보네요
It is a two-in-one interdental brush.
Be sure to use an interdental brush after brushing your teeth.
Even after brushing my teeth, foreign matter still came out.
I am currently using this product because it is 0.6mm, making it suitable for people with narrow gaps between their teeth.
It comes with a portable case, so it is convenient to carry around.
There are 10 pages included.
I tried various things, but interdental brushes were the best for removing debris.
Try using it after brushing your teeth.
My teeth are always clean since I started using an interdental brush.
