Did people use soot to brush there teeth?

Yes, people used soot to brush their teeth. Soot is a black powder that is produced when something burns. It is made up of tiny particles of carbon and other chemicals. Soot has been used for centuries as a cleaning agent, and it was once a common ingredient in toothpaste.

Soot was used to clean teeth because it is abrasive. This means that it can help to remove plaque and tartar from the teeth. Soot was also used to whiten teeth. The black color of soot can help to make teeth look whiter.

However, soot is not a good choice for brushing teeth today. It is too abrasive and can damage the teeth. There are many other, more effective ways to clean teeth.
