1. Whitening teeth with baking soda
Brushing teeth with baking soda may have a certain whitening effect, but long-term use may cause damage to the teeth themselves. It is recommended to try it occasionally, but not for a long time.
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, then dip a small amount of baking soda into a clean cloth or toothbrush and brush your teeth gently.
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 will damage teeth if used too much. It is best not to use it alone.
In fact, baking soda is still very good for whitening teeth, and the effect is also good. However, there are still many ways to whiten teeth with baking soda, which can be matched with edible salt and toothpaste. Therefore, if teeth are whitened, some of the above methods can be adopted for whitening.
