Short periods of time with a soother do not usually have much effect on the mouth, but if the soother is given regularly for a long period of time, the mouth may become deformed. In general giving a baby a soother for short periods of time occasionally usually has no serious effect and does not lead to deformation of the mouth. However, if babies often use soothers for long periods of time, it may have certain effects on the baby. For example, it may lead to deformation of the teeth, thus affecting the aesthetics of the baby’s teeth and even their normal function in the future. Serious cases may also affect the development of the baby’s upper and lower jaws, causing the baby to form a high palatal arch, resulting in the upper and lower teeth biting incorrectly, and then there will be a deformation of the mouth. In addition, the frequent use of pacifiers, may lead to excessive dependence on the baby pacifier, the emergence of not using the situation of crying, which has a negative impact on the baby’s sleep quality and physical development. Therefore, when crying, you can use the pacifier appropriately to play a soothing effect, but it is not recommended that babies use it regularly for a long time.
