1, sea salt

Sea salt is a well-known cleaning product with good anti-inflammatory and antibacterial effects. Usually, a little sea salt can be mixed with clear water for gargling, which can not only clean the oral environment, but also inhibit bacterial reproduction and reduce the formation of dental plaque, thus whitening teeth.

2. Lemon

Apply fresh lemon slices to the tooth surface, or use lemon juice. Lemon is rich in vitamins and citric acid, and has a strong cleaning effect, which can help remove oral bacteria, reduce smoke stains and dental plaque, and thus achieve the effect of whitening teeth. Pay attention to rinse your mouth with clear water in time after smearing your teeth, so as to avoid citric acid remaining for a long time and causing certain corrosion to your teeth.

3. Green tea

Usually, you can chew green tea often, or drink green tea water directly, one day 1 cup. If your stomach is cold, you can soak black tea in water. Polyphenols and catechins in green tea can effectively inhibit inflammation, help remove oral bacteria and reduce the formation of dental plaque. Therefore, drinking green tea often can prevent teeth from getting yellow.

Don't throw away the orange peel, collect it, dry it, and then grind it into powder. Sprinkle a little orange peel powder on the toothbrush every time you brush your teeth, brush your teeth gently for half a minute, and then brush your teeth normally with toothpaste. Organic acids contained in orange peel powder can soften tartar and smoke stains and make them easy to remove, thus achieving whitening effect. But this method can't be used for a long time.

5. vinegar

Take a few drops of white vinegar, melt it into a small glass of water, then gargle it in your mouth, let the vinegar fully contact your teeth, spit it out after one minute, and then brush your teeth normally with toothpaste. The acetic acid contained in white vinegar can dissolve the tartar and stains attached to teeth, making it easy to remove. However, due to the corrosion of acetic acid on teeth, this method can only be used temporarily in order not to affect the health of teeth.

6. Peanut powder

Before brushing your teeth every time, take a small amount of peanuts and grind them into powder, mix the powder into paste with a little water, then apply these peanuts to your teeth and leave them for a few minutes before you can brush your teeth with water normally. Peanut contains calcium, iron and other mineral elements, which can not only strengthen teeth, but also achieve the effect of whitening teeth.
