Test - Abrasivity

Abrasivity Testing of Test Dentifrice Compared with Standard Dentifrices Using Manual and Powered Toothbrushes (Westwood Research Laboratory, Inc.)

Purpose

To evaluate the abrasivity of the test dentifrice when used with standard manual and powered toothbrushes; to compare the abrasivity of the test dentifrice to that of other brands.

​

Abrasivity Scores
	All brushes:	​Standard:
Supersmile	62	45
Colgate Regular	68	52
Crest	70	64

​All of the results with dentin are well below the ADA permissible limit of 250, and are in the middle to lower range of abrasivity of those on the U.S. and world markets. Using the average for all brushes, the abrasivity score of Supersmile was lower than that for Crest or Colgate Regular.
