Tooth eruption and migration theories: can they account for the presence of a 13,000-year-old mesiodens in the vault of the palate?

A case of a mesiodens in the vault of the palate of a skull estimated to be approximately 13,000 years old is presented. The currently cited theories of tooth eruption were considered, and it was concluded that only the newly formulated BVT (blood vessel thrust) theory of tooth eruption can account for the migration of this mesiodens into that position.
