1.How many teeth?
Newborn babies do not usually have any teeth.Their front teeth begin to grow when they are about six months old.Most children have all their "milk"teeth by the time they are two years old.There are 20 teeth altogether.
The front teeth are used to cut food by biting.The back "doble"teeth are used to grind up the food.This makes the food easier to swallow.
Foods that are sticky and have a lot of sugar in them will make holes in the teeth if the teeth are not cleaned with a brush.
The "milk"teeth start to fall out when children are six or seven years old.The new teeth that grow in their place have to last forever!
