Tooth Health

Many people use toothpaste as part of their oral health care regimen. However, you should know that some toothpaste can cause problems. Many types of toothpaste are too abrasive and actually strip away tooth enamel which never grows back. The teeth may become sensitive when tooth enamel is worn away. Toothpaste’s abrasiveness is measured by its Relative Dentin Abrasively (RDA). The table below shows the RDA of some common toothpaste. We suggest that you use toothpastes with the lowest RDA ratings. In addition to finding a toothpaste that is minimally abrasive, we suggesting finding one with fluoride.
Fluoride helps strengthen enamel and prevent cavities. Toothpaste contains abrasives which help clean teeth. Unfortunately, these abrasives can sometimes strip away tooth enamel, making teeth sensitive toheat, cold, and sweets.

The RDA table:
0-70 = Low Abrasive
70-100 = Medium Abrasive
100-150 = Highly Abrasive
150-250 = Regarded as Harmful Limit
