Teething is a significant developmental milestone in a child's life, but it can also be a challenging time for both infants and parents. It's natural to wonder how long does the teething last.

Teething usually begins when a baby is around 6 months old, although it can start as early as 3 months or as late as 12 months in some cases. The process typically continues until a child has their full set of primary teeth, which is usually around the age of 2 to 3 years. By this age, most children have all 20 primary teeth, which include incisors, canines, and molars.

Throughout the teething period, new teeth usually emerge one at a time, with breaks in between. These eruptions can cause discomfort and irritability in infants, leading to symptoms like excessive drooling, gum swelling, fussiness, and disrupted sleep patterns.

The duration of teething symptoms can vary from child to child. Some infants may experience teething discomfort for only a few days around the time a new tooth is breaking through, while others might have ongoing symptoms for several weeks. However, it's important to note that teething itself is not a continuous process but occurs intermittently as each new tooth comes in.
