Facts about pacifier use
Prolonged pacifier use can silently change a childâs bite, jaw growth, and tooth alignment.
According to guidance from the American Academy of Pediatric Dentistry (AAPD), pacifiers are considered safe and appropriate during infancy, especially in the first year of life. However, when use continues beyond early toddler years, it can interfere with normal oral and facial developmentâoften without obvious symptoms at first.
Long-term pacifier habits are associated with open bite, increased overjet, altered tongue posture, and changes in how the upper and lower jaws grow. These changes may affect speech development, chewing efficiency, and can increase the likelihood of needing orthodontic treatment later in childhood.
The AAPD recommends gradually discontinuing pacifier use by around age 2â3, when the risk of long-term dental effects increases. Early guidance, gentle habit-breaking, and routine dental visits allow most childrenâs bites to self-correct naturallyâprotecting healthy jaw growth and a well-aligned smile without unnecessary intervention.
