White bread and refined flour products, such as crackers and simple biscuits, are harmful because the refined starches are quickly metabolized into simple sugars by enzymes in the saliva. When these foods are chewed, they form a sticky paste that clings to the tooth surfaces. This residue offers a readily available food source for bacteria, thus supporting acid production and raising the risk of interdental decay. Opting for whole-grain alternatives significantly reduces this rapid sugar conversion.
