Baking soda is one of the best ingredients that you can use to get rid of yellow teeth. It will help remove plaque and make your pearly whites shine.
Mix a quarter teaspoon of baking soda with a little toothpaste. Brush your teeth with this gritty mixture and rinse with warm water. Use it once or twice a week.
Alternatively, you can combine baking soda with lemon juice, white vinegar, or hydrogen peroxide.
You can make a whitening mouthwash by mixing one tablespoon of baking soda and one and a half teaspoons of hydrogen peroxide with one cup of cold water. Rinse with the mouthwash two or three times a day.
You can also scrub your teeth gently for at least two minutes with diluted baking soda. Do this twice in the first week, and then every 15 days. It is essential to note that excess use of baking soda can strip your teeth of its natural enamel.
