Evidence That Daily Vinegar Ingestion May Contribute to Erosive Tooth Wear in Adults

Vinegar ingestion at mealtime is gaining popularity for its antiglycemic effects; however, it is among the most acidic consumable substances. This study examined tooth wear in healthy adults participating in an 8-week randomized trial examining the effect of daily vinegar ingestion on insulin sensitivity and visceral fat reduction. Twice daily participants consumed a vinegar drink (two tablespoons vinegar in a cup of water; 3.6 g acetic acid) or a commercial vinegar pill (control, 0.045 g acetic acid) at mealtime. Participants were screened for dental erosion using the basic erosive wear examination (BEWE) by a blinded registered dental hygienist at trial baseline and week 8. Mean BEWE scores did not change in the control group but increased 18% in the vinegar group over the 8-week study (P = .038). Given the current popularity of vinegar as a medicinal agent, practitioners should caution patients who utilize this strategy on the possibility of erosive tooth wear. Trial registration: This trial was registered at ClinicalTrials.gov (NCT03577834) on July 5, 2018 and the institutional review board at Arizona State University provided ethical approval (STUDY00005418).

Keywords: BEWE score; acidic beverage; medicinal vinegar.
