Brush your teeth with a little baking soda and toothpaste. Brush for three times, and you will find that the teeth become white as jade, and the tooth rust naturally falls off.

Old vinegar and white vinegar can be used to whiten teeth (but vinegar essence can't be used), stay in your mouth for 1 minute to 3 minutes, then spit it out and brush your teeth. You can't do it continuously, but you can use it once every two months or so.

Chew raw peanuts, but don't swallow them. Instead, I use peanut crumbs as toothpaste to brush my teeth. Sticking to them can make your teeth white.

Put the broken bones of cuttlefish in a toothbrush as toothpaste, and the tooth whitening effect will be immediate (cuttlefish is actually squid and squid). There is a big white bone in its body. You can scrape a lot of white powder with your nails. When these powders are used as toothpaste, teeth will turn white. )
