False teeth could one day be a thing of the past, thanks to the discovery of an antibody that sparks the regeneration of lost teeth. By inhibiting the action of a gene called USAG-1, the antibody increases the availability of certain growth factors, and could eventually be used to help people grow a new set of pearly whites.
Publishing their work in the journal Science Advances, a team of researchers describes how they genetically modified mice to suffer from tooth agenesis, where some teeth fail to develop. Injecting pregnant mice from this line with the USAG-1 antibody, however, resulted in normal tooth development among their offspring. Moreover, a single administration of the antibody caused the growth of a whole new tooth in regular mice.
