Ø  Dogs have 42 teeth, cats have 30 teeth and pigs have 44 teeth. When you grow up, you will have 32 teeth. That’s if you don’t lose any to cavities.

Ø  A baby’s first teeth usually come in on the top front. They start coming in when a baby is about six to seven months old.

Ø  Even though whales are big, not all of them have teeth. Instead, they have rows of stiff hair-like combs (appendages) that take food out of ocean.

Ø  Mammals have only two sets of teeth, the first set they gen soon after birth, called the ‘milk teeth’ and a large set they acquire as an adult. In all other toothed vertebrates teeth just keep coming, not matter how many they lose there is always another one ready to take its place. These include fish, amphibians, reptiles and birds that have teeth in the first place.
