Generally speaking, a baby should begin to develop his/her first tooth around the age of 7 months and should normally have a full set of milk teeth by 2 years of age. Teething is often uncomfortable for your baby since his/her gums will be irritated so you may notice your baby biting on things more than usual, dribbling and appearing unusually fretful. These are common symptoms, and you can help to keep your baby calm by giving him/her a pacifier or teething biscuits.

As all babies are different, some babies may develop teeth as early as 4 months or as late as 13 months of age - these are all considered normal. If your baby is developing teeth rather late, make sure that your baby is getting enough calcium and vitamin D in his/her diet (e.g. by drinking enough milk) to enable the development of a full set of healthy teeth.

There are some instances where a baby may be born with teeth already. This is usually caused by a slightly premature development of teeth in the womb. Such teeth may be not fully formed and are likely to be loose in the gums. Should they fall out, they may end up blocking a baby's breathing track or esophagus, so it's probably best to consult a physician if your baby is born with teeth in order to take care of the situation.
