We all have teeth. In fact every person on this earth has teethes. We all know teethes are white in colour found in mouth of human beings. Teethes are usually used for purpose of mastication and to maintain food habits and structure of teeth one needs to brush its teeth. Well!! We all know why human beings brush their teeth but now we will know why animals won’t.
The teethes of animals are such that
they do not require brushing. Let’s take an example of snake which does not
require brushing because they use their teeth to capture their prey. They do
not have to eat; they just have to swallow their prey.
The only difference between human beings
and animals is of functional adaptations. For example, in plants the food which
they consume gets stored in cellulose wall. Although, here there is use of
teeth but there is no chewing. The food which they consume is mostly non-sticky
and raw. So, brushing is not important.
In contradiction, the cells of animals are not
closed within walls. This type of case can be present in carnivore’s animals
where they use their teeth only to catch their prey. So, this may be another
reason why animals do not brush their teeth.
It is important for human beings to
brush their teeth because the food which human beings consumed today is very
sticky and may cause dental problems. So, it is highly advisable that a person
should brush their teeth twice a day.
