Pacifiers

Board takeaway

Background and evidence

• Sucking meets nutritive or nonnutritive needs; pacifiers support security and self-soothing. Cultural context may influence family choices.
• This policy draws on a dental/medical literature review, including 557 search results; evidence strength varies by outcome.
• AAP guidance cited here delays introduction in breastfed infants until breastfeeding is established. A systematic review found no effect on breastfeeding prevalence or duration in healthy term infants through 4 months; do not generalize beyond that population/timeframe.

Benefits and appropriate use

• Offer at sleep onset for SIDS risk reduction; do not force a resistant infant. The policy describes good-quality patient-oriented evidence for this benefit.
• Potential uses: premature infants needing sucking-reflex development, early oral stimulation, NICU calming/stress reduction, and adjunctive pain relief during minor infant procedures.
• May be helpful when maternal medication or severe illness prevents breastfeeding.
• May reduce persistent digit sucking. Studies associate introduction before 4 months with less digit sucking and forced early cessation with prolonged finger sucking. Continued use beyond 14 months may help prevent a persistent finger habit; this is not a universal instruction to prolong use.

Safety and hygiene

• Choose one-piece construction to reduce breakage/choking risk. Shield should be firm, ventilated, and at least 1.5 inches across.
• Avoid hazardous cords, straps, or attachments; caregivers should inspect regularly for structural wear.
• Pacifiers harbor microbes and are associated with oral yeast infections. The source describes boiling for 15 minutes or antimicrobial spraying, preferably an agent such as 0.12% chlorhexidine, to reduce contamination; it does not supply a complete home-use protocol.
• Never offer honey-filled or honey-dipped pacifiers to infants or young children: botulinum spores can cause severe neurotoxic illness, including paralysis and respiratory compromise.

Age thresholds and clinical surveillance

• 6–12 months: reducing/eliminating use may lower acute otitis media incidence.
• After 12 months: policy highlights increased acute otitis media risk.
• Around 18 months/canine eruption: limiting or stopping use has been recommended to reduce posterior crossbite; use beyond 18 months can affect orofacial development.
• Before age 3: evaluate transverse occlusion. Habit-associated anterior open bite improves when use ends before this age.
• 36 months or longer: anterior open bite is more frequent; cessation by 36 months remains the policy goal.
• Examine for anterior open bite, posterior crossbite, and associated midline deviation. Duration influences malocclusion more than frequency. Increased overjet/Class II relationships are more strongly linked to digit habits, although the policy also lists Class II among prolonged pacifier risks.
• Speech-delay evidence is limited. Several hours of daily use may relate to atypical speech errors; a strong speech-based argument against all use is unsupported.

Timeline: change the counseling as use continues

These ages are counseling triggers, not guarantees that harm starts on a birthday. Assess duration/frequency, open bite and crossbite, and help families stop with positive reinforcement. Changing pacifier shape does not replace habit cessation. Retain the safety guidance and the sleep-related SIDS association above.

Pacifier design and cessation

• Fit, size, nipple geometry, and shield design affect palatal interaction; transverse narrowing contributes to crossbite. Biometric selection is promising, with further research encouraged.
• Some studies favor orthodontic designs for open bite, but reviews find insufficient evidence to prefer them for preventing malocclusion. Crossbite differences between types are not consistently significant.
• A thin-neck study reported differences between designs but did not demonstrate benefit over cessation.
• Prefer recognition/incentives for non-use over criticism or restraint; power struggles may prolong the habit. Cessation can be child-led or caregiver-supported.
• For a toddler with an emerging open bite or crossbite, address continued use now and follow the occlusal response as the habit ends. Switching to an “orthodontic” design does not provide the demonstrated benefit of cessation.

Common board traps

Answer aloud

What should parents know before introducing a pacifier?

Use it safely for soothing/sleep-related SIDS-risk reduction, with an early cessation plan.

• For breastfeeding infants, wait until breastfeeding is established.
• Choose one-piece construction with a firm vented shield at least 1.5 inches across.
• Avoid cords and honey-filled/honey-dipped pacifiers.

Which ages change pacifier counseling?

Prolonged use changes risk over time; aim to end nonnutritive sucking by 36 months.

• Use positive reinforcement; assess actual use and occlusal effects rather than age alone.

A 20-month-old has an open bite. Should the family just switch designs?

Changing shape does not replace reducing and ending a persistent habit.

• Assess duration, frequency, open bite, and transverse occlusion.
• Help the family limit/stop use with positive reinforcement.
• Do not promise that another pacifier design will correct the bite.
