Assuming that you know what a toothbrush and dental floss are and use them, and assuming that you make the occassional trip to the dentist, neither is harmful. The sugar in sweetened sodas, if left unchallenged by dental hygiene, can promote tooth decay. The artificial sweeteners in "diet" soda is proven not to promote tooth decay.


The acid in diet coke causes tooth decay, regardless, although the acidity in diet coke is less than apple juice/apple cider. Although both will stain your teeth.


They are both horrible for your teeth, but if you want to choose one then go with the diet coke because it doesn't have as much sugars in it.
