Baby Teeth, Teething Cycle.
When teeth first start to come in, for some babies they may have sore or tender gums. To help ease their teething pain, gently rubbing your child’s gums with a clean finger, a small, cool spoon or a wet gauze pad.
You can also give the baby a clean teething ring or a frozen baby cloth to chew on. If your child is still cranky and in pain, you may want to consult your dentist or physician. Generally children have a full set of 20 primary teeth by the time they are three years old.
