I heard charcoal is bad for your teeth because it grinds the enamel over many years.

I have this toothpaste. I bought it from Costco when it was on sale a while back. It doesn't really make your teeth as sensitive as other whitening toothpastes (especially 3D ones), but I instead noticed it's harder on my gums. Overall decent toothpaste, but everyone has a preferred one. Just figured you all should know.

Tried to pull the best tl;dr summary I could find out of the PDF for anyone not looking to read in full:
The results showed increasing Ra values for all treatment groups after brushing for the equivalent
of one month and three months. A tooth’s rough enamel would be a strategic place for bacteria to
adhere to the tooth’s surface. The presence of bacteria in the oral cavity is one of the causes of high
caries and periodontal disease risk [8]. The threshold value for Ra that might cause the retention of
bacteria is 0.2 μm [8]. An Ra value above the threshold would be a strategic place for bacterial growth
and the accumulation of plaque causing a high risk of caries and periodontitis [8].

Based on the research that has been done, after brushing for the equivalent of one month, the Ra
values of the three groups were still below the threshold. However, after brushing for the equivalent of
three months, the Ra value of Charcoal® Formula toothpaste crossed the threshold of bacterial
retention. The increased Ra value nearly doubled from the initial roughness. Therefore, people need to
reconsider the use of toothpastes containing charcoal for the long term (more than three months)

I heard that coconut oil toothpaste makes your teeth more white.

I thought they were sealed systems and didn't need fluid changes? Lifetime fluid.

I saw the deal on Amazon and posted it here. I did not make this product and nor do I have any intention of up selling it. I have used it and found it to be effective so I shared it on RFD. If you don’t like it, scroll past and move on.

No, I think I'll continue to let people know about the harm from using products that are promoted on here. If you want to keep using it, or other people want to, that's fine. But people should know about what they're using.
