Home remedies for teeth whitening include oil pulling, eating crunchy fruits and vegetables, and brushing on a mixture of baking soda and lemon juice, reports Natural Society. These techniques are effective and do not require extensive dental knowledge.
Oil pulling is an ancient Indian treatment that involves swishing with a tablespoon of pure oil, preferably coconut oil, for approximately 20 minutes. Afterward, the individual spits out the oil instead of swallowing it, notes WebMD.
Apples, carrots and celery are good choices for crunchy snacks that can whiten teeth. These crispy foods remove bacteria and stains during chewing. The acids they contain, which are similar to the ones found in teeth-whitening products, are also a huge bonus, according to Natural Society.
Combining a small amount of baking soda with fresh lemon juice is one of the most popular home remedies for whitening teeth. Those who practice this method apply the mixture to their teeth, leave it on for about a minute and promptly remove it with a toothbrush, explains Natural Society.
Wood ash is also commonly used for teeth whitening, but using it is dangerous due to the presence of potassium hydroxide, or lye, states Dodge. Rubbing sea salt on teeth also whitens them and may brighten them. However, sea salt is often mixed with vinegar, which can permanently damage teeth.
