An inmate at the Washington State Penitentiary has filed a federal lawsuit claiming prison officials refused to provide him with dentures after removing all of his rotten teeth, forcing him to live on a diet of soft and blended food. Jimmy de la Mater arrived at the Walla Walla prison in September 2013. Three months later, one of his teeth broke when he bit into an apple, and the prison’s dental staff pulled the rest. But because he would be in prison for less than five years, the lawsuit claims, state officials refused to provide the 42-year-old with dentures.
