Relative dentin abrasivity (RDA)

Relative dentin abrasivity (RDA) is a standardised measurement of the abrasive effect that the components of the toothpaste have on a tooth. The RDA scale was developed by the American Dental Association (ADA) and according the ADA safe level of abrasions of toothpaste ranges from 0 to 250.

The more sensitive dentin, the coefficient of the abrasiveness should be lower

  • 30-70 – low abrasive, toothpaste used for sensitive teeth
  • 70-100 – medium abrasive, toothpaste for everyday use
  • 100-250 – highly abrasive, toothpaste used for tooth discoloration and cigarette stains

The RDA indicator in toothpaste COMPLETE CARE is:

SENSITIVE TOOTHPASTE – 38 GUMS PROTECTION TOOTHPASTE – 78 WHITENING TOOTHPASTE– 105

92% of respondents confirm the efficacy of COMPLETE CARE SENSITIVE TOOTHPASTE (protection against hypersensitivity) after only 2 weeks of use * COMPLETE CARE toothpaste do not contain animal ingredients * The study was conducted on 25 subjects on a period of 2 weeks.
