it has an outer layering of acid which reacts with the afood we eat like chocolates..... and it changes the colour of our teeth to yellow and to avoid this we brush our teeth with toothpaste which acts as a base and neutralize the effect of acid.....
therefore it is always advised to brush our teeth twice a day

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.
