치간칫솔 많이들 쓰시는군요
My gums used to get bad because sweets would get stuck between my teeth, but using an interdental brush helped take care of them a bit. There is a huge difference between using an interdental brush and not using one, so I always make sure to pack one when I go on vacation or travel for a few days.
If you have bad gums, try using Changgyeo.
