Dr. Ashley Lucas explains that apple cider vinegar softens tooth enamel for about 30 minutes. Brushing during this window strips the enamel, which doesn't grow back. Rinse with water instead and wait at least 30 minutes before brushing.

This one surprises almost everyone. But after drinking apple cider vinegar, your enamel temporarily softens for about 30 minutes. It's going to be easier to infiltrate through the enamel. If you brush during that window, you're going to be more likely to scrape away the protective surface of your teeth, which you do not want. Enamel does not grow back. The better approach is simple. Rinse your mouth with plain water and wait at least 30 minutes before brushing your teeth. Your saliva will naturally neutralize the acid and reharm harden the enamel.
