How often to change the pacifier

　　Although pacifiers can satisfy children's tactile stimulation, they must not make children addicted to these products. If the baby keeps sucking on the pacifier, it will promote the continuous secretion of saliva, resulting in the loss of many digestive enzymes. In addition, sucking on a pacifier can cause spitting up and bloating. This will affect the growth and development of the child's oral and jaw system for a long time. When the child is seven or eight months old, he should try to throw away the bottle, and by the age of one or one and a half years, he should learn to drink from a cup.

　　What's more, there are substances in poor quality pacifiers that are not good for the baby's development.

　　Zhang Jiahao, a dentist at Mackay Hospital, said that long-term use of poor-quality pacifiers and improper sucking postures also caused displacement of deciduous teeth and bottle mouths. The so-called displacement of deciduous teeth refers to the situation that the upper row of deciduous teeth is pushed forward and the lower row of milk is squeezed backward due to long-term pacifier sucking, resulting in the problem of malocclusion and open bite. The bottle mouth refers to the relaxation of the tension between the upper lip and the lower lip due to long-term sucking habits, forming upturned lips.

　　At the same time, the pacifier should be replaced regularly, even if it is not obvious that it is broken, it should be replaced every 3 months. If the pacifier is found to be discolored or cracked, it should be replaced in time.
