Using Baking Soda and Aloe Vera
Few people know that aloe vera can whiten teeth, in addition to its well-known benefits for skin and hair. Aloe vera contains vitamins B, C, and E, essential amino acids, and minerals like iron, calcium, magnesium, manganese, and zinc, among other health-promoting components. These nutrients are also particularly effective for whitening teeth.

Additionally, propolis, anthraquinones and saponins in aloe vera contribute to bacterial inhibition, reduction of inflammation and healing of oral wounds.

Pineapple, lemon and soda

A can of sugar-free Coke, 100g of pineapple, two lemons, and two tablespoons of salt create a solution that instantly cleans your teeth, removes tartar, and improves your oral health.
