Does chocolate cause tooth decay?
Another yes and no answer. Because of the amount of sugar in many types of chocolate and cookie recipes, the answer is yes. Sugar breaks down the enamel in teeth and promotes tooth decay. However, the presence of the cocoa powder in chocolate is actually nearly as beneficial for teeth as fluoride. This is another area where how much chocolate is digested goes a long way toward answering the question. Too much chocolate, and the sugar levels will far outweigh the benefits of the cocoa powder.
