What 𮯌 means
It carries the tooth-decay meaning into a Japanese simplified form. “Extended shinjitai” means an unofficial simplification applied to kanji outside Japan’s everyday-use list. Here, 歯 (“tooth”) replaces 齒. An oracle-bone form of the older character pairs teeth with an insect, likely evoking decay; Shuowen Jiezi defines it as teeth eaten by worms. Japanese references also give “toothache.”
