However, dental experts believe that this is only a supportive solution and cannot replace professional bleaching methods.
According to recommendations from the American Dental Association (USA), baking soda has mild abrasive properties, helping to remove stains on the surface of teeth caused by food, drinks such as coffee, tea or tobacco. However, improper or too frequent use can wear out tooth enamel, making teeth more sensitive to temperature and acid.
Baking soda can help improve teeth whiteness to a mild extent, but the effect is not long-lasting and does not affect the color of the inner teeth. Therefore, this method is only suitable for temporary surface cleaning needs.
Note that baking soda works most effectively when used as an ingredient in toothpaste, instead of being formulated strongly at home. Brushing vigorously or in combination with acidic substances like lemon can increase the risk of enamel damage.
Safe use is usually to mix a small amount of baking soda with water or toothpaste, brush lightly for 1-2 minutes and should only be done 1-2 times a week.
