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 (for example, before going out on a date, I found my teeth are so yellow). Well, it can also get rid of bad breath:)

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

3. When brushing your teeth, using some yeast powder on your toothbrush can help whiten your teeth (a method commonly used by MODEL).

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

Chew raw peanuts, don't swallow them, and brush your teeth with peanut crumbs as toothpaste, which can make your teeth white.

6, use the bones of cuttlefish, crush them and put them in a toothbrush to make toothpaste, which is immediate (cuttlefish is cuttlefish, squid. It has a big white bone. If you scrape with your nails, a lot of white powder will come out. If this powder is used as toothpaste, teeth will turn white. )
