Since our stomach acid is so strong, why does vomiting not scar our throat and mouth?
In: 7
Yes, it does when it is too frequent.
Our throats and mouths are constantly covered by protective mucus (and saliva), which works quite well to limit exposure to the acids. However, if the vomiting is very frequent, the repeated (tiny) exposure adds up. This is most pronounced by erosion of the teeth as acids eat away the enamel in more pronounced ways.
