if you took your stomach acid poured it into a cup and then dropped one of your teeth inside the acid would immediately begin breaking them down the tooth's enamel would start to dissolve and depending on the material the Cup itself would begin to deteriorate so if stomach acid is this strong why doesn't it eat through the walls of your stomach well it's because they're coated in a thick layer of mucus this mucus protects the stomach lining by creating a barrier that Shields against the stomach acid without the mucus your stomach would literally eat itself
