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.
A tooth is not a lever. A tooth could be part of the lever formed by the jaw. A tooth could be a wedge.
A small hard bristled brush on the end of a hanle about 200mm long for the cleaning of teeth, there are also electricaly run versions of this.
