Baking soda can be used for brushing teeth and whitening teeth.

However, baking soda itself is an alkaline substance. If you brush your teeth with alkaline substances for a long time, it will also have a corrosive effect on the teeth themselves, so I suggest you not use it for a long time, otherwise it will do harm to your mouth and teeth. Can not be used for a long time, and whitening teeth depends on daily protection.

1. Methods of whitening teeth with baking soda

1. Use baking soda and salt together

Add some salt and water to a proper amount of baking soda, and mix well, not too thin, so that it can be applied to teeth, and then gently brush your teeth with a clean cloth or toothbrush.

2. Use baking soda with toothpaste

Just sprinkle a little on the toothpaste when brushing your teeth. However, this substance mixed with baking soda and toothpaste can only be used once a day, because baking soda is alkaline, and it will damage teeth if used too much. Don't use it alone.

2. Precautions for whitening teeth with baking soda

Brushing teeth is not white, and the reason why it is white is the visual effect formed by brushing away the tartar and pigment on the tooth surface. Baking soda takes advantage of this cleaning effect to whiten teeth.
