Hi, Can you tell me if charcoal is too abrasive to use in toothpaste? My new dentist tells me it is, and that I should only use it once a month. Then he showed me an abrasiveness chart with about 50 different kinds of toothpaste on it, and not a single one had charcoal. Feeling a bit confused.
Thank you, Marissa
Hi Marissa. Below is a chart that I found for toothpaste abrasiveness from Dental Assistant Blog. It lists from the lowest abrasive to what would be considered the most harmful.
Our Ultra Fine Coconut Shell Activated Charcoal Powder falls in the category of the lowest abrasive at 7 and our Detox at 8. Maybe your dentist was thinking of a more gritty charcoal powder and did not realize the incredible fine powders that we carry. Even our Bamboo falls into the low abrasive at 44 microns.
0 – 70 = low abrasive
70 – 100 = medium abrasive
100 – 150 = highly abrasive
150 – 250 = harmful limit
You might want to take a look at this link and see how your present toothpaste is stacking up to charcoal, it is quite revealing! Let me know if you found this helpful.
Keep in mind that dental experts do not all agree on the validity of RDA values, in part because test results have varied in different labs. That said, a general rule of thumb is that whitening toothpaste tends to be more abrasive, and toothpaste for sensitive teeth tends to have low abrasiveness.
