Are sugary liquids worse for teeth than sugary foods?

Neither are good: Both for your teeth, and for your overall health, high sugar snacks/foods can cause havoc. If your teeth are covered with plaque, especially between teeth where you can only clean by flossing or using oral irrigator, sugars will just feed the bacteria in the plaque which will then make acids that will harm your teeth. As my g'mother used to say, "All things in moderation."
