SO two days ago i went to school and was going to brush my teeth. when i started brushing i noticed a mustardy taste. me not thinking anything of it i continued to brush with toothpaste to take away the taste. a day later i felt sick with a dry throat smotach felt empty and puffy eyes. My friend said i looked to have an illergic reaction but denied anyting . I am becoming concerned about a possible diease. The other thing is that the tooth brush has a traveling case top for it and after i was done i put the case on right after brushing.
