In a bizarre case from the UK, a 62-year-old man developed a severe neurological disorder, and doctors learned it probably had something to with his dentures. Or at least, with the stuff keeping them in place. Published on Monday in the online journal BMJ Case Reports, the man had described pain and numbness in his legs that had grown worse over six months. He started out just needing a cane, but eventually he could not even leave his house.
