No. For most of human history, people never brushed their teeth. "Inherited' would mean that babies spontaneously would start cleaning their teeth because their brain was hard-wired to give them that urge. But that isn't so. The only natural urge we have is to want to eat or drink stuff that has way too much sugar in it and so make our teeth rot. But brushing your teeth is an acquired habit.
