I wouldn't call it that. It's more like a lever. You hold one end of the toothbrush and the other end of the lever is the bristled working end against the teeth and gums. As the fulcrum is on the working end, there is no mechanical advantage for the toothbrush lever.
It works by killing germs i.e. bacteria, viruses, fungi and protozoa. There are two main types of toothbrush sanitizers for consumers. One type uses UV light to kill germs. The other type, which is more effective, uses steam to kill germs. Given that some germs can make us sick, killing the germs found on the toothbrush therefore sanitizes the toothbrush.
A tooth is not a lever. A tooth could be part of the lever formed by the jaw. A tooth could be a wedge.
