Apple cider vinegar, like any acidic vinegar, can damage tooth enamel if used excessively. The acetic acid found in apple cider vinegar can erode tooth enamel, which can eventually lead to tooth sensitivity issues. However, it is important to note that most people can consume apple cider vinegar without causing significant damage to their tooth enamel. Here are our two tips for minimizing the potential risks to your teeth if you use apple cider vinegar: 1. Dilution: Do not drink pure apple cider vinegar, dilute it in water. 2. Use an Archie Straw: If you drink diluted apple cider vinegar, use a straw to minimize direct contact with your teeth.
