A3. TRUE – Toothpaste must undergo tests to measure abrasiveness by RDA (radioactive dentin abrasion) value. The scale can be anywhere between 30 to over 250. The complex testing process involves brushing radioactively treated samples of dentin and then measuring the RDA value. The higher the value, the more abrasive the toothpaste being tested is.
