12. Baking Soda Teeth Whitening

Baking soda is a popular DIY method for achieving brighter, whiter teeth at home. To safely use this method, combine a teaspoon of baking soda with a small amount of water to form a thick paste. Gently brush your teeth with this mixture for no more than two minutes, once or twice a week. According to dental experts at Colgate, baking soda effectively removes surface stains due to its mild abrasive properties. However, they caution against overuse, as excessive brushing can lead to enamel erosion. Always follow up with regular toothpaste to maintain optimal oral health.
