Brew a less acidic coffee A recent visit to the dentist opened my eyes to a new aspect of tooth care I hadn't realized: apparently, the acidity of coffee can increase the growth of cavities if the teeth are not brushed directly after.  Unfortunately, brushing the teeth directly after my morning coffee isn't really an option.  Also, unequivocally, giving up my morning coffee isn't an option either.

That led me to wonder, is there any way of brewing a normal coffee in a way that would lead to a beverage with a higher pH, that still has the taste and caffeine of a normal coffee?
You can try switching to cold brew coffee which is reportedly 67% less acidic than regular brewed coffee. 

Regarding the caffeine amount, Wikipedia notes:


  Although less caffeine is extracted with the cold brew method, a higher coffee-to-water ratio is often used, between 2 and 2 1/2 times. This may compensate for this difference in solubility, resulting in a brew with equal, if not more, caffeine (although this is unlikely)


Additionally, despite the name, cold brew coffee can be enjoyed hot as well. Cold brew is essentially a coffee concentrate if steeped long enough. You can cut your cold brew with boiling water and serve it hot (Source), so you don't need to necessarily change the way you enjoy your coffee (if you enjoy it hot). 

Hope this is helpful!
