Toothpaste Abrasiveness. Posted by admin on Apr 4, 2011 in Blog | Comments Off. The toothpaste you are using may be wearing away the enamel and dentin on your teeth, especially at the gumline! The use of âgritâ in toothpaste is not unlike the use of grit on sandpaper. The more grit there is, the more effective it is at removing stain and plaque. Unfortunately, a significant downside is the destruction of tooth structure. There is an abrasive index for toothpastes called the RDA Index. The higher the value, the more abrasive it is. At or below 45 may be acceptable balance between benefit and risk if you must use toothpaste. Over 45 is a matter of how quickly the loss of tooth structure can occur based on the RDA, frequency of use, type of toothbrush and brushing technique.
