Should Your Toothpaste Contain Baking Soda, or No?
Posted on 8/10/2020 by office
Toothpastes with baking soda have been endorsed by the American Dental Association (ADA). Therefore, a toothpaste with baking soda contains a low-abrasive substance – one that will remove surface stains but will not erode the enamel. The following information will give you further details about the abrasion levels of toothpastes.
What Is the Relative Dentin Abrasion (RDA) Value of Toothpastes?
The relative dentin abrasion (RDA) value measures the abrasiveness of certain toothpastes. Therefore, you can find out if a toothpaste is safe to use from its RDA value. When you brush only with baking soda, it may feel rather gritty and therefore damaging. However, on the Mohs Hardness of Materials Scale (the one used to test the hardness of diamonds), tooth enamel is rated 5. Baking soda ranks at 2.5. Because baking powder is softer than enamel, it is considered lower in abrasion and safe to use when brushing. To elaborate on this finding, the ADA has compiled an RDA chart that shows the abrasiveness of certain toothpastes.
How Are RDA Ratings Computed?
An RDA for a toothpaste between 0 and 70 means that the product is extremely low in abrasiveness. A medium RDA falls between 70 and 100 while a high RDA registers between 100 and 150. A toothpaste with a high level of abrasiveness will have an RDA between 150-250. Plain baking soda has an RDA of 100 while toothpaste with baking soda, on average, comes in at 110 on the RDA scale. Therefore, you can see that baking soda carries a low level of abrasion and therefore can be used to remove surface stains.
We can help you make the right choices in toothpaste for your at-home dental care. Usually, toothpaste with fluoride is a safe and effective dentifrice. However, we realize patients have certain likes and dislikes. We just want to make sure you choose a safe toothpaste for you and your family.
