Vinegar is not only bad for a person's teeth, it is among the greatest contributors to tooth enamel loss, according to Sharecare. A study of teenagers revealed a dramatic increase in enamel erosion among those who regularly consume vinegar-laden foods, such as salad dressings, potato chips and pickles.
Teens suffer the greatest risk of enamel erosion because their enamel isn't fully mature, reports Sharecare, though all people face risks. Using a mouth rinse after consuming foods or drinks with vinegar minimizes the risks of erosion. WebMD also notes that the acid in vinegar is bad for the esophagus as well.
