After studying more than 1,000 men for up to 30 years, the researchers found that those who drank one or more cups of coffee each day had fewer teeth with bone loss the hallmark of periodontal disease which can lead to loosening and ultimately loss of your teeth. The researchers also found no evidence that even moderate or heavy coffee drinking was associated with any other markers of periodontal damage, such as bleeding of the gums or development of bacteria-collecting pockets around the teeth.

The researchers believe that the antioxidants in the coffee may explain the protective measure of the brew.

Plus, its less acidic than many other common beverages, like fruit juices, sodas, and energy drinks. According to a study in the British Journal of Nutrition, all of those drink but not coffee were shown to weaken teeth's protective enamel.
