As the popularity of DIY increases, so does the ambition to find a method to whiten teeth using everyday ingredients lying around our house. Remember, “natural” doesn’t always mean healthy. Truly, DIY whitening may brighten your teeth, but harm them in the long run.
Fruits
This method uses acidic fruits such as lemons, oranges, and cider vinegar, also acidic, mixed with an abrasive such as baking soda to brush on your teeth. You could get many surface stains brightened, but long term use will damage the enamel of your teeth. This combination will wear the enamel layer of the tooth, exposing the dentin, which is yellow. Sensitivity will also increase without the protective enamel covering.
Scrubbing
The idea of scouring your teeth with ingredients like a mixture of 
baking soda/peroxide or activated charcoal paste may not put that shine back into your pearly whites. There is no evidence that the use of any product with charcoal is safe or effective, according to the ADA. Both of these mixtures are too abrasive on your teeth. Only the enamel whitens, and the use of gritty substances can wear that layer away. The dentin, as we have said earlier, the soft yellow color. Whitening works on the enamel, not dentin.
Oil Pulling and Tumeric
Save the oils and spices for tasty, healthy meals. Evidence has not verified that swishing coconut in your mouth (oil pulling) or using spices like Tumeric whitens teeth.
