The pros and cons of pacifiers

Pacifiers help babies (and their parents) get through periods of crankiness, crying, and pain. They are ideal for those times when the baby is either not hungry or too full to eat—but still needs the comfort that sucking provides.

Pacifiers as we know them today, with the familiar guard and handle, were first patented around 1900. Although they have been widely used ever since, pacifiers sometimes raise questions from parents and medical professionals. Many studies have examined their benefits and drawbacks.

According to the policy guidelines of the American Academy of Pediatric Dentistry, both finger and pacifier sucking are considered normal behavior in infants and toddlers. And when used correctly, pacifiers don’t cause medical or psychological problems.

Here are some of the advantages of using a pacifier:

  • Soothes and quiets the child

  • Produces an actual pain-relieving effect if the child is hurt or uncomfortable

  • Helps development of muscles around the mouth

  • Slightly decreases the risk for sudden infant death syndrome

Parents should also be aware of the potential health issues:

  • Overuse of pacifiers, especially past age 3, may interfere with the normal positioning of teeth and shape of the mouth, particularly when permanent front teeth are emerging.

  • Increased chance of dental cavities. Never dip a pacifier in honey or other sugary liquids.

  • Increased risk for latex allergies if a latex pacifier is used

  • Possible early weaning if the infant is breast-fed

  • Contamination with germs if the pacifier is not properly cleaned. Wash pacifiers often with warm, soapy water and rinse thoroughly.

  • Choking and suffocating hazards. Never use the nipple from a baby bottle as a pacifier. Never hang a pacifier on a string around the baby’s neck.

  • Possible increased risk for ear infections

If you have questions or concerns about pacifiers, talk with your child’s dentist.
