We have to brush our teeth, otherwise they decay so soon. But animals, without even the habit of mouthwashing with water, still have their teeth strong and functioning in old life. How this happens.
I searched Google to find an answer, everywhere it is written that the cause is difference in food habit. But do you think animals don’t get carbohydrate foods in their meal. Leave the predator animals…what about the cows and goat, they take vegitable foods like potato, grass, which contain carbohydrate in high amount. Think of guineapig, they take same type of foods like us…beans (cooked), and other stuffs. Even pet dogs take the same food we take, so why they still have so strong teeth?
