1. Try pulling oil
The practise of rinsing the mouth with oil to remove debris and microorganisms is known as "oil pulling." Some study indicates that cleaning the mouth with particular oils may assist to whiten the teeth, while it is not a replacement for consistent brushing and flossing. To test out this technique, however, spit out the oil after rinsing the mouth with it for around 20 minutes after brushing.
2. Using baking soda to brush
The surface of the teeth can be carefully polished clean of stains with baking soda. Although it has been proven to be safe to remove stains, some individuals are concerned that baking soda is too harsh and could damage enamel. Baking soda may be able to lessen plaque since it may also aid to fight bacteria.
3. Peels of lemon, orange, or banana
Some individuals assert that applying the peels of lemons, oranges, or bananas on your teeth would whiten them. Citric acid, which can be found in the peels of some citrus fruits, is thought to help whiten teeth. For around two minutes, gently rub the fruit skins across your teeth. After eating, be sure to completely rinse your mouth and brush your teeth.
4. Activated charcoal
The stains on your teeth can be removed using activated charcoal. Because of its great absorption capacity, charcoal is thought to be able to remove pigments and stains from your teeth. Additionally, it is supposed to eliminate toxins and microorganisms from the mouth.
