PACIFIERS: Do they really do structural damage?
Pacifiers can be wonderful tools for soothing infants—and they can have benefits during the early months of life. ❤️
But prolonged pacifier use can affect developing mouth, teeth, palate and orofacial muscles.
With continued use, children may be at increased risk for:
👄 Anterior open bite – the front teeth don’t come together and actually form around the shape of the pacifier
🦷 Posterior crossbite – the upper and lower back teeth don’t align properly causing chewing problems
👄 Changes in the shape and width of the upper dental arch causing narrowing of the jaw and a high vaulted palate
🗣️ Changes in the developing oral-motor environment which may lead to speech disorders
‼️One important point to note: It’s not simply how often a child uses a pacifier—it’s also how long the habit continues.
🦷 The American Academy of Pediatric Dentistry notes that prolonged pacifier use beyond about 18 months potentially negatively influences the developing orofacial complex.
👄 As SLPs, we look beyond speech sounds. We consider the whole orofacial system—including resting posture, tongue position, lip closure, chewing, swallowing and oral habits.
💡 Parents don’t need to feel guilty about pacifier use. The goal is education, gradual weaning when appropriate, and collaboration with your child’s pediatrician, pediatric dentist, SLP and other professionals when needed.
If you’re wondering whether your child’s pacifier use may be affecting their oral development, talk with your pediatric dentist and/or SLP.
❤️ Early awareness can make a difference!
