Below is a chart comparing results with the information found on the Internet
Teeth cleaner experiment Info on the Internet
Baking Soda Very abrasive Not mentioned
Arm and Hammer Not abrasive Peroxides harmful to gums
Topol Slightly abrasive Very, very abrasive First of all, the Internet sites did not mention baking soda as a teeth cleaner at all. This could be a problem, since people who actually use plain baking soda to brush their teeth. They are probably unaware of the damage that it can cause given the lack of information on the subject. Baking soda was very, very abrasive. Second, the Internet sites did not comment on whether Arm and Hammer toothpastes were abrasive, but they did point out that baking soda-based toothpastes contain peroxides that can harm your gums with their bleaching agents. Next, the Internet sites warned against use of harsh toothpastes such as Topol describing them as much too abrasive. In the experiment it was discovered that Topol is only slightly abrasive, and in particular, its abrasiveness is insignificant in comparison to baking soda. It is odd that the site should warn against Topol and not against
baking soda when the latter is so much more abrasive. In comparing my results, they have realized that the information on the Internet is quite
limited: it did not mention baking soda, it did not comment on whether Arm and Hammer was abrasive, and it warned how abrasive Topol is.
