Everything has peaks and valleys in it when viewed with the help of microscope. Our tooth enamel also has. The particles of sugary foods stick in the valleys. Some bacteria attack that part and start eating the sugar particle but with it they also eat the enamel.

Answer:
Sugar present in chocolates and sweets gets broken to acids by bacteria present in the mouth. This lowers the pH in the mouth. Tooth enamel is made up of calcium phosphate, which gets corroded when the pH in the mouth is below 5.5. To prevent tooth enamel from decay, toothpaste is used because it is alkaline and neutralises the acid produced in the mouth and helps to prevent lowering of pH in mouth.
