A baby s first tooth usually appears between the ages of 5 and 7 months. Some babies get their first tooth a little earlier and others a little later. Often, the two middle bottom teeth come through the gums first, followed by the middle four upper teeth.
Teething is the process of teeth moving and breaking through the gums.
This is a normal developmental stage for your baby. The following are the most common symptoms of teething. However, each baby may experience symptoms differently. Teething does not cause colds, diarrhea, or high fever, but it can make a baby uncomfortable. If your baby becomes sick around the same time teeth are coming in, it is important to evaluate the symptoms of that illness independently of the teething.
