IPA: /pɪˈɔːrɪə/
KK: /pɪˈɔrɪə/
A condition characterized by inflammation and infection of the gums, often resulting in the discharge of pus and loosening of teeth.
The dentist diagnosed her with pyorrhea after noticing the inflammation in her gums.
Pyorrhea is formed from "pyon" (from Greek "πύον", meaning pus) and "rhea" (from Greek "ῥεῖν", meaning to flow). The word describes a condition characterized by the flow of pus, particularly in relation to gum disease.
Think of 'pus' ('pyon') flowing ('rhea') from the gums, which helps you remember that pyorrhea refers to a condition involving pus flow in the mouth.
