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.
By training, I am a American Board Certified Pediatrician. But in my younger years I grew up with natural alternatives. As a mom I have tried to incorporate both for my kids and it has worked wonders. And finally, as I am studying natural & alternative medicines, I realize the beauty and wisdom of living closer to earth. Hence in my practice I integrate both...for acute ailments I follow American Academy of Pediatrics recommendation but for simple and/or chronic conditions I prefer natural alternatives.
In western training we were raised to think that "health is the absence of symptoms and problems". But eastern sensibilities has educated me that "Health is state that allows one to use the full capabilities of their body, mind and intellect. Therefore, healthy living is a balanced state of well being: physically, mentally, socially and spiritually." This implies that healing is not a "one-pill-fits-all", but a personalized experience.
