First off why is rodentistry a thing? Apparently, tons of rat owners like for their rats to take a look in their mouth and clean away. Dentist of course don't recommend this and a good old fashion tooth brush is the best way to go.
So gross! Even if every toothbrush in the world disappeared, I promise you wouldn't see me having a rat in my mouth. Ewww, I can't stop thinking about that little rat tongue on her teeth!
