"Actually you cant see animals suffering too much pain cause by their teeth".
The reason is because their teeth is still strong to handle so much cavity. We can also do that only if we dont brush our teeth with toothpaste to preserve its natural protection agains cavity. But since we dont follow their step coz our nature is different from them we are now vulnerable to those reason that will weaken our teeth.
Big reason that make us vulnerable is using a toothpaste without being aware that too much of using it may destroy natural protection of your teeth agains cavity. Toothpaste is dangerous because most of it contains high content of FLOURIDE which claiming that it will protect you from cavity, but reverse is the reality. Google it and you will be shocked in flouride exposed results.
It is true, so now that you know this fact you may stop or lessen your toothpaste consumption in a day. You can just use sodium chloride or asin, it is more cheaper and wont harm you unlike toothpaste with flouride content.
thanks sa DXN coz they made toothpaste without FLOURIDE:)
