A baby’s 20 primary teeth are already present in the jaws at birth and typically begin to appear when a baby is between 6 months and 1 year.
Most children have a full set of 20 primary teeth by the time they are 3. Check out this baby teeth eruption chart to see the order in which teeth break through and at what ages you can expect specific teeth to appear. Every child is different, but usually the first teeth to come in are located in the top and bottom front of their mouth.
When teeth first come in, some babies may have sore or tender gums. Gently rubbing your child’s gums with a clean finger, a small, cool spoon or a wet gauze pad can be soothing. You can also give the baby a clean teething ring to chew on. If your child is still cranky and in pain, consult your dentist or physician.
