Usually, the teething irritability period lasts about 15-30 days, with individual differences. Some babies may show symptoms such as irritability, crying, fever and salivation during teething, which is called the irritable period. Most babies have been teething for about 1 year, and most of them will not have obvious irritability after they have gradually adapted to the itchy gums and the discomfort caused by the teething process. Parents should always pay attention to the dynamics of their babies’ teething. If your baby is irritable for a long time after teething, you can go to the pediatric department of the hospital for a detailed examination to clarify the cause. In addition, parents should do a good job of oral hygiene care during the teething period, parents can use a clean medical cotton swab or sterilized cotton gauze with light saline to wipe the residue at the gums after each feeding.
