It's not that I neglect brushing my teeth.
I'm worried because my teeth are yellow. I brush my teeth three times a day, and I do it within 30 minutes after meals.
I saw in the newspaper that there are toothpastes that advertise removing tartar and whitening teeth, but honestly, I don't trust them, so I haven't been using them.
