Teething is a process in which the first set of teeth, called primary teeth, erupt and break through the gums. Although the timing for each child varies, most babies get their first tooth at age 6 to 10 months and have a full set of 20 primary teeth by the age of 3 years.
Teething symptoms may begin about 3 to 5 days before a tooth breaks the skin. But symptoms can be present off and on for 1 to 2 months. The most common symptoms of teething include:
