Though turmeric is notorious for leaving a yellow stain on almost anything and everything, it can be a great tool to naturally brighten and whiten yellow teeth. Although the exact reason as to why it works is not known, many swear by it. Try it to believe it!
Turmeric is also good for sensitive teeth and dental problems like toothaches and gingivitis, thanks to its anti-inflammatory, antiseptic and antibiotic properties. The medicinal properties mainly come from a component in turmeric called curcumin.
Along with turmeric, this homemade natural teeth whitener includes baking soda and coconut oil. Baking soda, also known as sodium bicarbonate (do not confuse with baking powder), works as a mild abrasive to remove stains from your teeth.
