ScienceDaily (Mar. 1, 2010) — Several genes affect tooth development in the first year of life, according to the findings of a study conducted at Imperial College London, the University of Bristol in the UK and the University of Oulu in Finland. The research, published February 26 in the open-access journal PLoS Genetics, shows that the teeth of babies with certain genetic variants tend to appear later and that these children have a lower number of teeth by age one. Additionally, those children whose teeth develop later are more likely to need orthodontic treatment.
