BENEFITS OF BAKING SODA
Brushing teeth with baking soda aids in dislodging plaque built up on the teeth aside from giving you a brighter smile. Common beverages such as coffee, red wine, soda and tea and smoking cigarettes are major contributors to staining of the teeth. In addition to this, plaque accumulates and causes yellowish discoloration. Plaque contributes to dental decay and cavity formation and must be removed on a regular basis. Removal of plaque prevents a person from having bad breath. Baking soda is effective for both problems and has a bleach-like action resulting in effective whitening of teeth. Baking soda is perhaps the most affordable ingredient with a combination of tooth cleaner and whitener. A single box generally lasts for over one hundred brushes and costs around one dollar only.
BAKING SODA FOR TEETH: HOW BAKING SODA WORKS
Baking soda or sodium bicarbonate is a white, crystalline powder which is slightly alkaline in nature. When dissolved in water, this weakly alkaline releases free radicals (molecules that are very unstable and seek to bond to other molecules to increase their stability).
When baking soda is placed in the mouth, free radicals from the mixture interact with the stain molecules on the teeth enamel (protective coating) and oxidize or scrapes off the yellow and brown stains on the teeth. Thus, it breaks down the discoloration of the teeth resulting in brightening and whitening. The alkaline baking soda aids in neutralizing acidic bacterial wastes and facilitates an alkaline environment in your mouth that decay-causing bacteria do not develop well in. The rule of thumb is that, the higher the pH of the mouth the better for our teeth.
