I use Oral-B waxed dental floss for my oral care because even brushing with a toothbrush doesn't remove the food particles stuck between my teeth. Oral-B waxed dental floss is a very famous product, isn't it? I continue to use it because it doesn't break easily and food particles stick to the floss well. Whenever I feel like something is still off after brushing, I use Oral-B waxed dental floss to remove all the residue. It's really good.
