Did you know that baking soda has been used as a tooth cleanser for over 150 years? Unfortunately, it got the reputation as being abrasive to the enamel. Nothing could be further from the truth. Usually toothpastes are rated on a scale from 0 – 200 according to their abrasiveness.
This is called the RDA value or “Relative Dentin Abrasiveness”. Pure baking soda has an RDA of 7. Did you know the closest RDA to this is 35, which is Arm & Hammer baking soda toothpaste?
There are many reasons for using baking soda for brushing teeth. It is not only the least abrasive substance to use but it also whitens teeth, removes stain, and is also an effective germ killer against the bacteria that cause tooth decay and gum disease.
According to Pubmed, “An earlier clinical study demonstrated that brushing with a commercial Arm & Hammer dentifrice containing baking soda physically removed significantly more plaque than brushing with either of two commercial dentifrices which did not contain baking soda. However, little has been done to confirm these results and to compare baking soda-containing dentifrices with more recently commercialized non-baking soda dentifrice formulations. The objective of this study was to compare commercial dentifrices containing 20% to 65% baking soda and commercial dentifrices without baking soda in enhancing plaque removal efficacy of tooth brushing.”
Baking Soda and Your Teeth:
Sodium bicarbonate is believed to increase the pH in the oral cavity, which in turn neutralizes the harmful effects of bacterial metabolic acids. Sodium bicarbonate has an abrasive nature and can act as a polish agent, effectively eliminating the plaque layered on the tooth enamel. It is shown that sodium bicarbonate has an abrasiveness that is favorable for the enamel. Compared to other dentifrices, Sodium bicarbonate acts as an effective polishing agent. However, it is very important to use it in the proper amount.
Increases calcium uptake by the enamel which strengthens the enamel.
Many studies showed that bicarbonate has the ability to reduce dental plaque acidity and prevent dental cavities. Moreover, it can inhibit plaque formation on teeth and increase calcium uptake by dental enamel. The experts recognized this effect of bicarbonate on teeth back in October 1985 when a tooth powder containing sodium bicarbonate was patented in the USA.
Is a polishing agent
Due to the abrasive nature of sodium bicarbonate, plaque layered on the enamel of teeth are scrubbed off. With reference to the relative dentin abrasion tests done on straight sodium bicarbonate, its abrasiveness is favorable with low abrasivity to the overall state of the enamel. This is as compared to other oral formulations, dentifrices and brands. Sodium bicarbonate, therefore, when used in the correct amount, is an effective polishing agent.
How to Brush with Baking Soda
1. Pour some baking soda into a small dish or container.
2. Dampen your toothbrush with water.
3. Dip the toothbrush in the baking soda and get as much baking soda to stick to it as possible.
4. Brush your teeth for two minutes.
5. Brush the tongue for 20 seconds as well. Many germs live on the tongue.
6. Rinse with water.
