What was done

Healthy adults participating in an 8-week randomized trial were assigned to consume either a liquid vinegar drink (two tablespoons of vinegar in a cup of water; 3.6 g acetic acid) or a commercial vinegar pill (control; 0.045 g acetic acid) twice daily at mealtime. Erosive tooth wear was assessed at baseline and week 8 using the Basic Erosive Wear Examination (BEWE) by a blinded registered dental hygienist.

What was found

Mean BEWE scores did not change in the control group over the 8-week study but increased by 18% in the liquid vinegar group (P = .038).

Why it matters

Liquid vinegar is widely consumed for metabolic benefits, but regular ingestion can cause measurable enamel erosion in as little as eight weeks.

Limits

The abstract does not state the sample size (n), baseline participant demographics, or absolute BEWE scores. Dental erosion was evaluated as part of a trial focused primarily on metabolic outcomes, and long-term dental consequences or protective strategies were not reported.
