Almost every parent gets a deadline for the pacifier, and almost nobody gets the same one. One year, from a pediatrician. Two, from a relative. Three, from the dentist. Whenever they decide to give it up, from the internet.
The published guidance is more useful than any of those, because it is not a single deadline at all. It is three separate thresholds, each attached to a different risk and each asking something different of you: ear infections, in the second half of the first year; the bite, from around 18 months; and a genuine outer limit at 36 months.
Here is what each one says, where the evidence is strong and where it is thin, and why the most common mistake is not waiting too long — it is taking the pacifier away too early and getting a thumb instead.
Why the Pacifier Is Not the Same Problem as the Thumb
The two habits get lumped together as "nonnutritive sucking," and for the bite they do behave similarly. For everything else they are not the same problem, and the differences run in the pacifier's favor.
The pacifier has a documented benefit no thumb has. The American Academy of Pediatric Dentistry's Policy on Pacifiers, adopted in 2022, states it plainly: "the AAP recommends offering a pacifier when an infant is placed to sleep due to its protective effect on the incidence of sudden infant death syndrome (SIDS), but a pacifier should not be forced on resistant infants." The AAPD lists the rest of the benefit column too — helping premature infants develop the sucking reflex, comfort and soothing, an analgesic effect during minor procedures, and "preventing a persistent finger-sucking habit."
That last one deserves more attention than it gets, because it cuts directly against the instinct to wean early. The AAPD writes: "Allowing the habit to continue beyond 14 months of age may help prevent a persistent finger habit because forced early cessation of pacifier usage has been associated with prolonged finger sucking."
Read that twice if you have a one-year-old and a plan to take the pacifier this month. A pacifier can be left at home, put in a drawer, or handed to the "pacifier fairy." A thumb travels. Trading the first habit for the second is a downgrade, and the AAPD is telling you it happens when the first one is ended under pressure. Our guide to thumb sucking and when to worry covers the other side of that trade; if your child already has both, treat the thumb as the harder one.
The First Threshold: The Second Six Months, and Ear Infections
The earliest risk on the list has nothing to do with teeth.
The AAPD states flatly that "pacifier use is a risk factor for otitis media in infants and children," and adds a specific, actionable finding: "the incidence of acute otitis media may be reduced by decreasing or eliminating use of a pacifier in the second 6 months of life."
That sentence rests on an unusually practical study. Niemelä and colleagues published a controlled trial in Pediatrics in 2000 across 14 Finnish well-baby clinics, paired by size and parental social class, with one of each pair randomly assigned to an intervention: nurses counseled parents of children under 18 months to limit pacifier use, with a leaflet and instructions to restrict it. They recruited 272 children at the intervention clinics and 212 at the controls.
Continuous pacifier use at 7 to 18 months fell 21 percent in the intervention group, and acute otitis media per person-month at risk was 29 percent lower at the intervention clinics. Comparing children directly rather than clinics, "the children who did not use a pacifier continuously in either of the clinics had 33% fewer AOM episodes than the children who did." The authors' conclusion is the most useful line a parent of a six-to-twelve-month-old can take away: "Its restriction to the moments when the child was falling asleep effectively prevented episodes of AOM."
Nobody told those families to throw the pacifier out. They were told to stop letting it live in the child's mouth all day. That is the first threshold, and it is not a weaning deadline — it is a narrowing. Pacifier for sleep onset, which is the use the SIDS evidence supports anyway. Not for the stroller, the car seat, the grocery store, or the floor time between lunch and nap. If your child is prone to ear infections, this is the change worth making first.
The Second Threshold: Around 18 Months, and the Bite
The second threshold is set by a tooth.
The AAPD notes that "to limit the development of a posterior crossbite, discontinuing or limiting pacifier use when canines emerge (approximately 18 months of age) has been recommended," and its closing policy statement names the same window: use "beyond 18 months can influence the developing orofacial complex, leading to anterior open bite, posterior crossbite, and Class II malocclusion."
Three findings in that policy matter for how you plan around this.
Duration beats frequency. The AAPD reports that "malocclusion was affected by duration more than frequency," and that "the percentage of open bite was significantly greater as the duration of nonnutritive sucking continued beyond 3 years of age." A pacifier used intensely for a short stretch is a different exposure from one used lightly for years. That is good news if you are narrowing use rather than ending it — and bad news if you are quietly letting it ride.
The pacifier shape is not the solution. One systematic review found orthodontic pacifiers "induce less open bite compared to conventional pacifiers," but the AAPD also reports that "two reviews comparing orthodontic versus conventional pacifiers stated evidence was insufficient to support a preference," and that pacifiers "interact with the palate differently based on their fit (ie, design and size) regardless of whether they are labeled conventional or orthodontic." The clearest test: in a prospective study of toddlers averaging 20 months who already had an anterior open bite, a thin-neck pacifier beat the conventional one on overbite and overjet changes at P less than 0.001 — and yet "no improvement in either pacifier group compared to cessation of pacifier use was found." Buying a better pacifier does not substitute for using it less.
The finger is worse for some things. The AAPD notes that "increased overjet and a Class II malocclusion are more strongly associated with a finger habit versus a pacifier habit" — another reason not to force the trade.
If a dentist or orthodontist has already flagged a bite change, our guide to whether myofunctional therapy can fix an overbite explains which bite problems are habit-driven and which belong with an orthodontist instead.
The Third Threshold: 36 Months, and a Deadline That Is Not Flexible
The outer limit is stated the same way by both the dental and the speech-language organizations.
The AAPD's policy asks providers to give parents anticipatory guidance that includes "the discontinuance of nonnutritive sucking habits by 36 months of age," and recommends establishing a dental home by 12 months precisely so there is time for that conversation. The American Speech-Language-Hearing Association's practice portal on orofacial myofunctional disorders lists "chronic nonnutritive sucking and chewing habits past 3 years of age" among the contributing causes, notes that "prolonged nonnutritive sucking is a risk factor for increased malocclusion," and cites the same target of stopping by three.
The AAP's parent-facing guidance on pacifiers and thumb sucking sounds looser, and parents who find both documents sometimes read a contradiction into them. It says that if a child "sucks strongly on a pacifier or his thumb or fingers beyond 2 to 4 years of age," the "behavior may affect the shape of their mouth or how their teeth are lining up."
There is no contradiction. The AAP page describes where the visible damage usually shows up; the AAPD sets the date by which you should be clear of it. And both agree on the reassuring part: the AAPD says "an anterior open bite with pacifier use will improve after elimination of the pacifier before age 3," and the AAP says that if sucking stops before the permanent front teeth come in, "there's a good chance their bite will correct itself."
So the third birthday is not a cliff edge where harm begins. It is where the window for free self-correction starts closing, and where a habit becomes a pattern worth addressing deliberately.
What About Speech? The Weakest Argument, Honestly Stated
Pacifier-and-speech is the claim parents hear most often and the one with the least behind it. The AAPD reviewed it directly and wrote: "Evidence linking pacifier use to concerns with speech development or speech delay is limited. Recent research suggested that while prolonged day-to-day pacifier use lasting several hours may have significance with atypical speech errors, a strong speech-related justification against pacifier use is not evident."
The study most often cited on the other side is worth reading properly. Barbosa and colleagues assessed 128 three- to five-year-olds across three preschools in Punta Arenas, Chile, using parent questionnaires on sucking history with speech scored by a licensed speech pathologist against age norms. They found a three-fold increase in the relative odds of a speech disorder for finger sucking (OR 2.99, 95% CI 1.10 to 8.00) and for pacifier use of three or more years (OR 3.42, 95% CI 1.08 to 10.81). Those are real associations — drawn from 128 children in one city, with retrospective parent recall and confidence intervals wide enough that the true effect could be nearly nothing or very large.
The stronger version of the speech concern is not about pronunciation at all. It is about where the tongue learns to live. A pacifier held in the mouth for hours keeps the tongue low and forward and the lips apart, and ASHA describes the typical oral resting posture as the opposite — "the lips closed; nasal breathing." A low, forward resting tongue is the posture associated with a tongue thrust swallow and with the lisp that will not clear with articulation practice alone, and it travels with mouth breathing more often than with any one habit.
That is a mechanism argument, not a trial result, and it should be offered to you as one. It is a good reason to keep the pacifier on a schedule. It is not a reason to believe a pacifier has already cost your two-year-old their speech.
How to Actually Retire It
Here the evidence thins out in a way worth knowing about, because it means the confident step-by-step plans you will find online are not built on trials.
The 2015 Cochrane review by Borrie and colleagues evaluated interventions for stopping non-nutritive sucking habits and found six randomized or quasi-randomized trials covering 252 children aged two and a half to 18, all at high risk of bias. And then this: "Digit sucking was the only NNSH assessed in the studies." Not one trial studied how to stop a pacifier habit — everything tested, from palatal cribs to reinforcement schedules, was tested on thumbs. What the review does support, at low quality, is the general shape of the behavioral approach: pooled data from two trials of positive reinforcement favored it over no treatment in the short term (RR 6.16, 95% CI 1.18 to 32.10), and one trial of 57 children found the same in the long term (RR 6.25, 95% CI 1.65 to 23.65).
The AAPD is specific about which direction to push: "positive reward for pacifier cessation (eg, recognition or incentive for each day of non-use) is preferable to negative reinforcement (eg, criticism, restraint) to avoid power struggles which could extend the duration of the habit." The AAP says the same in plainer language — praise and star charts work, "avoid harsh words, teasing, or punishment," and stop any method that leaves your child afraid or tense.
Taken together, a sequence that follows the three thresholds rather than fighting them:
Second half of the first year. Narrow, do not remove. Pacifier for sleep onset and real distress, nothing else. This is the ear-infection change, and it also shrinks the habit you will eventually end.
From about 18 months. Set the end date and work backward. Daytime use is finished. If the pacifier is still in the car or the diaper bag, it comes out of both.
Between 2 and 3. Retire it, with the child involved. Most families do better with one clear, celebrated event — the last pacifier goes into a box, gets mailed to the pacifier fairy, gets traded for a chosen toy — than with weeks of negotiation. Expect two or three rough nights and plan a replacement comfort, because the pacifier was doing a job.
If it is still here at 3. Stop improvising. This is the threshold at which both the AAPD and ASHA treat the habit as a clinical matter rather than a phase, and a structured program beats another round of reminders.
A note on timing you can control: do not schedule this for the same month as a new sibling, a move, a hospital stay, or the start of daycare. The pacifier is a coping tool, and taking a coping tool away during the event it would have covered is how a two-day transition becomes a two-month one.
The Safety Rules That Have Nothing to Do With Age
Four of the AAPD's pacifier rules apply at every age, and they are easy to miss because they sit in a different part of the conversation from weaning.
- Single-piece construction. Pacifiers made in one piece "are less likely to break apart and become a choking hazard," and they should be checked regularly for "structural wear that poses a safety risk."
- Shield size. The AAP recommends the shield "be firm, have ventholes, and measure at least 1.5 inches across (ie, large enough not to pass completely into the mouth)."
- No straps, cords, or attachments. The US Consumer Product Safety Commission prohibits them, and the AAP's parent guidance says never to tie a pacifier to a crib or around a child's neck or hand. Clip-and-ribbon sets sold as accessories are not an exception.
- Never dip it in honey. The AAPD notes that the FDA recommends against pacifiers containing or dipped in honey, because honey contains Clostridium botulinum spores, and that "cases of infant botulism in Texas were attributed to commercially-available honey-filled pacifiers." Those products still turn up at markets and online.
And one that applies to every rigid thing a toddler drinks or sucks on: the measured injury risk is about falling, not about the object. The same 2012 Pediatrics analysis we covered in our comparison of cup types attributed 86.1 percent of bottle, pacifier, and sippy cup injuries in children under three to a fall while using the product, with the mouth the most commonly injured area.
When It Is Worth Having Someone Look
Most pacifier transitions need patience, not a professional. A few are telling you something, and the signals are specific rather than a general sense that it is going badly. Worth an evaluation:
- A dentist or orthodontist has named an anterior open bite, a posterior crossbite, or a narrow palate.
- Your child's lips are apart at rest, or they breathe through the mouth while reading, watching television, or sleeping — the pacifier may have been a passenger rather than the cause, and the airway question comes first.
- The tongue sits forward or between the teeth at rest, or pushes forward on a swallow.
- A lisp or distorted /s/, /z/, or /sh/ has not cleared with articulation practice.
- The habit is still present at three, a thumb replaced it, or your child is past four and still sucking strongly on anything.
For the habit itself, our thumb sucking and pacifier habit elimination program is built around the child's own motivation rather than appliances or aversive tastes, because a child who understands why they are stopping is the one who actually stops. For the pattern a long habit can leave behind, myofunctional therapy for kids covers what resting posture, lip seal, and swallow retraining look like at each age.
What We Do With This at Bloom
Laura Friedman, MS, CCC-SLP, QOM holds both a CCC-SLP and a Qualified Orofacial Myologist credential, which is why pacifier questions get answered here with two lenses rather than one: what the habit may have done to the bite, which belongs with your dentist, and what the mouth is now doing at rest, which is ours.
An orofacial myofunctional therapy evaluation looks at tongue resting posture, lip seal, nasal versus mouth breathing, and the swallow — the four things a long sucking habit is most likely to have shaped. Sometimes the finding is that the habit left nothing behind and the teeth will sort themselves out, which is an answer we will give you plainly rather than selling you a plan. Sessions run in person at our Dallas office and by telehealth nationwide, and habit work translates well to a screen because the coaching is aimed at the parent and at the child's own awareness.
Frequently Asked Questions
When should a child stop using a pacifier?
There is no single date, but there is a firm outer limit. The AAPD's 2022 Policy on Pacifiers asks for "the discontinuance of nonnutritive sucking habits by 36 months of age," and notes that use "after 12 months of age can increase the risk of acute otitis media and beyond 18 months can influence the developing orofacial complex." Read as a staircase: narrow to sleep in the second half of the first year, get deliberate from around 18 months when the canines arrive, be done by the third birthday.
Is it bad to give a baby a pacifier for sleep?
No — for an infant that is the use with the best evidence behind it. The AAPD policy states that "the AAP recommends offering a pacifier when an infant is placed to sleep due to its protective effect on the incidence of sudden infant death syndrome (SIDS), but a pacifier should not be forced on resistant infants." If you are breastfeeding, the AAP advises waiting "until breastfeeding is going well," which "usually takes about 3 to 4 weeks."
Do pacifiers cause speech delays?
This is the weakest of the arguments for weaning. The AAPD's own reading of the literature is that "evidence linking pacifier use to concerns with speech development or speech delay is limited," and that "a strong speech-related justification against pacifier use is not evident." The study most often cited found roughly three-fold odds of a speech disorder with pacifier use of three years or more, but in 128 preschoolers with a confidence interval from 1.08 to 10.81. The better reason to retire it on time is the bite and the resting posture.
Is it better to stop cold turkey or taper off?
Nobody has tested this for pacifiers. The 2015 Cochrane review on stopping non-nutritive sucking habits covered six trials and 252 children and states that "digit sucking was the only NNSH assessed in the studies." It did find, at low quality, that positive reinforcement beat no treatment. In practice, narrowing use to one place and then ending it is easier than an abrupt stop, because it shrinks the habit first.
Are orthodontic pacifiers better for the teeth?
Not reliably. The AAPD cites a review finding orthodontic pacifiers "induce less open bite," but also two reviews concluding "evidence was insufficient to support a preference for orthodontic pacifiers preventing malocclusions." In a prospective study, a thin-neck pacifier beat a conventional one on bite changes but produced "no improvement in either pacifier group compared to cessation of pacifier use." Duration matters more than design.
My child gave up the pacifier and started sucking their thumb. What now?
This is a known trade, and it is the main reason not to rush an infant off the pacifier: the AAPD notes that "forced early cessation of pacifier usage has been associated with prolonged finger sucking," and that letting the habit continue past 14 months may actually help prevent a persistent finger habit. If the swap has already happened, you are working on the harder of the two habits, and a structured habit-elimination program is a better next step than more reminders.
Will an open bite caused by a pacifier correct itself?
Often, if the habit ends early enough. The AAPD states that "an anterior open bite with pacifier use will improve after elimination of the pacifier before age 3," and the AAP says that if sucking stops before the permanent front teeth come in, "there's a good chance their bite will correct itself." What does not self-correct on its own is a forward resting tongue or a thrust swallow pattern that outlasted the habit — a separate question from the teeth, and the one a myofunctional evaluation answers.
Not Sure Whether the Pacifier Left Anything Behind?
If a dentist has mentioned the bite, or the habit is still here past three, it is worth twenty minutes of someone's attention. Schedule a free consultation with Laura Friedman, MS, CCC-SLP, QOM — in person in Dallas or online nationwide — and we will tell you plainly whether anything needs retraining or whether time will do the work.
