1, put vinegar (old vinegar, white vinegar is ok, but not vinegar essence) in your mouth 1 to 3 minutes, then spit it out and brush your teeth. The effect is very good! But even the teeth will feel very sour, and the numbness (feeling will last for about 2 minutes) will not last. Do it often, about once every two months, and it will be fine. Otherwise, it's bad for your teeth. It is an emergency method (such as finding yellow teeth before going out on a date) and can also get rid of bad breath.

2. Dry the orange peel, grind it into powder, brush your teeth with toothpaste, and your teeth will soon turn white.

4. After brushing your teeth, wipe each tooth with lemon juice.

5, chew raw peanuts, don't swallow, use peanut crumbs as toothpaste to brush your teeth, which can make your teeth white.

6. Use cuttlefish bones, crush them and put them in a toothbrush for toothpaste.
