강해져라피부야
치간칫솔로 꼼꼼하게 양치하시는 분들 많으시네요
This is an interdental brush I always use when brushing my teeth.
It is also good for preventing tartar.
It is also the best for preventing cavities between teeth!!
I use Type I, depending on the user
I've noticed that some people find the L-shape comfortable!
I recommend buying the one with a lid because it allows for cleaner use and is also portable.
