Hi Dear !
_______________________________________________________
Brushing teeth twice in a day is very important because  when we eat our food (sugar) or carbohydrate it stick to the teeth and there is self cleansing process in our teeth with the help of acids which will lead to tooth decay if we don't brush daily because toothpaste is basic in nature it will neutralize the acidic effect also it is very important to brush just after sleeping because in all night our tooth will decay easily.

Answer 2

We must brush our teeth twice a day. It helps us in maintaining a fresh breath. If we do not brush our teeth twice a day, bacteria would build up. It prevents from the build up of plaque, which may cause gingivitis. Brushing our teeth twice a day, makes our teeth stronger, fresher and whiter faster.
