How to whiten your teeth at home

1. Adhesive teeth whitening agent

2 teeth whitening gel or whitening toothpaste

Use an oral rinse made with hydrogen peroxide and water. If used daily before brushing, it will naturally whiten your teeth. The ratio of hydrogen peroxide to water is 50:50. The method of use is as follows.

Hold about 2 tablespoons (30ml) of mouthwash made with hydrogen peroxide and water in your mouth and rinse for 1 minute. When foam begins to form, it means the mouthwash is taking effect. When hydrogen peroxide reacts with bacteria in the mouth, foam is produced.
Spit out the mouthwash and rinse your mouth with water.
Brush your teeth as usual.

4 Baking soda

Wet the toothbrush with water and dip it in baking soda. Wet the toothbrush with water so that the baking soda adheres well.
Brush your teeth for 2 minutes. Spit out baking soda if necessary.
If your mouth feels stinging after brushing your teeth with baking soda, see a dentist. It could mean you have a cavity.

5 Overall lifestyle improvement

Avoid foods and beverages that can stain teeth.
Eating foods that are good for your teeth
