You can also wash it away with a glass of water. It's common in cafes to get a glass of water with coffee. After every sip of coffee take a sip of water. This helps wit hydration as well.

  coffe does not dehydrate. that myth was debunked long time ago. the reason you get a cup of water to your coffe at cafes is to drink the water BEFORE you drink the coffee. the water helps to neutralize any (bad) taste in your mouth (eg after a meal) so you can get the most out of the aroma of the coffee.

Are you sure they were warning about drinking it, and not its effect of worsening bruxism?

He was incorrect based on the existing evidence. Sugar-laden diets combined with both a mineral poor diet (ergo, no dental remineralization) and a constant subclinical dehydration (did you drink your gallon of water today? no? saliva is the vehicle for said remineralization, and is one of the first to be hit during early stages of dehyrdation; water is required to maintain the pH of your mouth) is bad your teeth. The worst coffee can do is stain already poor enamel. Coffee is hardly acidic, and its a myth that its more destructive. Now, if you drink your coffee with sugar? Thats bad, learn to drink it black. https://www.ada.org/en/~/media/ADA/Public%20Programs/Files/JADA_The%20pH%20of%20beverages%20in%20the%20United%20States https://www.ada.org/en/~/media/ADA/Public%20Programs/Files/J... Anything on this list that is below a pH of 5 you should strongly avoid. pH is a log scale, so, pH of 5 is 10x worse than 6, 4 is 10x worse than 5 or 100x worse than 6; the hydroxyapatite in tooth enamel starts to dissolve at 5.5, and coffee is only 5.11, well within your mouth's ability to handle. If he warned you because you suffer from bruxism, not because of tooth decay, for most people, just follow the normal rules for coffee that everyone else should follow: avoid caffeine 6 hours before bed.

  I agree with you that acidity is the main cause of enamel erosion. The correlation between beverage acidity and tooth decay is such that I think we should highly discourage children from drinking any carbonated or acidified drink . I disagree that "pH of 5 is 10x worse than 6, 4 is 10x worse than 5 or 100x worse than 6". pH is logarithmic with respect to hydrogen ion activity but hydrogen ion activity is not linear with respect to enamel erosion in a human mouth [1].

    Interesting read, thanks. Really drove home the point of how bad soda and energy drinks are.
