1. Whiten Yellow Teeth at Home: Toothpaste, salt, baking soda, and lemon juice

A tablespoon of toothpaste, a pinch of salt, some baking soda, and four to five drops of lemon juice should all be combined in a bowl. Clean your teeth for 4-5 minutes with this mixture. After just a few use, you’ll notice the difference. Employ this technique every two months.

A word of caution: If you have dental issues, avoid using any of these techniques at once and stay away from at-home whitening.
