Pacifier Teeth: Causes, Effects, Damage, and Treatment

Pacifiers often called dummies or soothers are a lifesaver for many parents. They help babies self soothe and even reduce sudden infant death syndrome (SIDS) risk when used safely at bedtime. Pacifiers for teething (a type of teether pacifier) can also comfort sore gums and ease teething pain. However, if used too long, pacifiers can cause dental problems.

“Pacifier teeth” refers to the misalignment of baby teeth caused by prolonged sucking. In this guide, we’ll explain what causes pacifier teeth, the effects on your child’s mouth, and how to prevent and treat these pacifier induced dental issues.

What Are Pacifier Teeth?

Pacifier teeth are not an actual illness, but a nickname for bite changes in toddlers caused by constant pacifier use. In plain terms, this means baby teeth shifting position due to the pressure of sucking on a pacifier (or a thumb) for extended periods. The continuous sucking action can push the upper front teeth outward and even change the shape of the roof of the mouth (palate).

Orthodontists explain that these bite issues often appear as an open bite, overbite, or crossbite various forms of misalignment. The good news is that pacifier teeth aren’t always permanent. Many dental experts note that if the habit stops early (usually by age 3), the bite can often correct itself as the adult teeth come in.

Causes of Pacifier Teeth

Long term pacifier teeth happen for a few clear reasons:

• Extended Use: The most common cause is allowing a child to use a pacifier well beyond infancy. For example, one study found nearly 71% of children still using pacifiers past age 4 showed bite misalignments, compared to only 14% of those who quit by age 2. In other words, the longer a child sucks on a pacifier (or thumb), the more likely their teeth will shift.
• Constant Pressure: Sucking applies steady pressure to the teeth and jaw. Over months or years, that pressure can slowly push teeth out of their normal positions. Toddlers who vigorously suck on pacifiers effectively reshape their mouth to accommodate the pacifier, leading to gaps, buck teeth, or a narrowed palate.
• Duration and Frequency: How often and how long a child uses a pacifier each day matters. Studies show a direct relationship between hours of pacifier use and the severity of malocclusion (tooth misalignment). A child who naps or sleeps with a pacifier is at less risk than one who keeps it in all waking hours.
• Thumb Sucking and Combined Habits: Pacifier teeth aren’t unique to pacifiers. Thumbs, fingers, blankets, or toys that a child sucks on can create the same forces on developing teeth. In fact, experts often say that any prolonged non nutritive sucking habit (pacifier or thumb) can cause similar problems.

In short, the root cause of pacifier teeth is excessive sucking. The risk goes up sharply if the habit continues past about 2-3 years old. After age 3, children’s permanent teeth are beginning to form, so misalignment from pacifiers becomes more problematic.

Effects of Pacifier Teeth on Oral Health

Prolonged pacifier use can lead to several dental issues. These effects are usually most noticeable once a child has a full set of baby teeth. Common problems include:

• Overbite or Open Bite: A classic sign of pacifier teeth is an open bite (where the front teeth don’t touch when the mouth closes) or a deep overbite (upper front teeth protruding over the lowers). Both happen because the pacifier holds the teeth slightly apart or forward.
• Crossbite: Chronic sucking can also cause a crossbite, where upper teeth fit inside the lower teeth on one or both sides. If left uncorrected, crossbites can lead to uneven jaw growth.
• Protruding Front Teeth (Buck Teeth): Many toddlers with pacifier teeth develop front teeth that jut outward. Orthodontists note that constant sucking essentially “flips” the front teeth forward. This can give the child a buck toothed appearance.
• Gum Recession & Cavities: In extreme cases, intensive pacifier use has been linked to gum recession (where the gums pull back from the teeth). Additionally, some parents dip pacifiers in sweet liquids to encourage use. This adds sugar to the mouth, which breeds cavities. Research confirms that pacifier use combined with sugary exposure significantly raises the risk of decay.
• Speech and Eating Difficulties: When bites are significantly misaligned, children may struggle with certain sounds or have trouble biting/chewing food correctly. Speech delays and feeding problems have been observed in kids with severe pacifier induced malocclusion. In some cases, the misalignment can affect a child’s appearance or self esteem as well.

Even though these issues sound alarming, they are often reversible. Doctors emphasize that if pacifier use stops early enough, many of the bite changes will self correct as the child grows. Regular dental check ups can catch any developing problems, so parents know if (or when) orthodontic help is needed.

Preventing and Managing Pacifier Teeth

Thankfully, parents can take practical steps to use pacifiers safely and lower the risk of pacifier teeth. Key strategies include:

• Wash and Replace: Keep pacifiers clean and replace them regularly. Never let children share pacifiers sharing can spread bacteria and prolong use. Using a fresh, undamaged pacifier keeps the habit under control.
• No Sugary Coatings: Avoid dipping pacifiers in honey, sugar, or anything sweet. Not only is this unsafe for infants, but it also places sugar on the teeth and gums, promoting decay. Let the pacifier soothe without added treats.
• Limit Use in Time: Make the pacifier a special tool rather than a constant companion. For example, only give it at naptime or bedtime, not for every fussy moment. Gradually reduce pacifier use as the baby gets older. The American Academy of Pediatric Dentistry (AAPD) advises beginning to wean around age 2 and fully stopping by age 3. This timeline minimizes potential dental effects.
• Choose the Right Pacifier: Use a pacifier that fits your child’s age and mouth. Many pacifiers are labeled by age group. An orthodontic pacifier (with a flat, symmetrical nipple) is often recommended as it theoretically keeps the jaw in a more natural position. Look for BPA free, medical grade silicone designs with a well ventilated shield. While no pacifier can guarantee zero impact, choosing high quality, age appropriate models is the “best pacifier for teeth” strategy.
• Offer Alternatives: When your baby is teething, try offering other relief methods alongside the pacifier. Teething toys, chilled (not frozen) teethers, or a cold, clean washcloth can all give gum pressure without sucking. Breastfeeding can also be soothing and supplies nutrients. By rotating comfort methods (swaddling, rocking, or gentle gum massage), the child won’t rely exclusively on a pacifier.

By combining these tips, parents can greatly reduce the chance of pacifier related damage. Remember: moderation is key. A pacifier used only at sleep time and weaned in toddlerhood generally poses little harm.

Choosing the Best Pacifier

What is the best pacifier to protect teeth? The answer lies in thoughtful selection and limited use. In terms of design, look for orthodontic pacifiers. These have a flat or slightly curved nipple rather than a fully rounded one. They are engineered to distribute pressure evenly over the palate, which can lessen forces on the teeth. Many pediatric dentists favor these orthodontic styles because they encourage a more natural tongue position and jaw alignment.

Material also matters. The best pacifiers for teeth are typically made from one piece, medical grade silicone or natural rubber (latex). These materials are soft and flexible, which is gentler on developing gums and teeth. Always choose a pacifier that is BPA free and meets safety standards. Additionally, pay attention to size. As your baby’s mouth grows, they will need the next size up. An improperly sized pacifier (too small or too large) may sit wrong in the mouth and alter pressure on the bite.

No single pacifier can completely prevent pacifier teeth. The key is combining the “best” pacifier (orthodontic, age appropriate, quality material) with wise usage. Even a top rated pacifier can cause issues if left in constantly. In practice, using the recommended pacifier and putting it away when not needed gives your child comfort without undue risk.

Treatment and Correction of Pacifier Teeth

If your child already shows signs of pacifier teeth, the approach depends on their age and the severity of misalignment:

• Wean as Soon as Possible: The first step is to stop the pacifier habit. Once the pacifier is out of the picture, many bite issues begin to correct themselves. In fact, if a child quits by age 2 (before all baby teeth are in place), the bite often realigns within 6-12 months without intervention. During this catch up period, regularly monitor progress. In mild cases, no further treatment may be needed.
• Encourage Alternatives: For older toddlers resistant to giving up, some parents try gentle strategies. According to orthodontists, one trick is to cut a small slit or hole in the pacifier’s nipple. This breaks the suction and makes it less satisfying to use. Others use sticker charts, positive reinforcement, or even bitter tasting solutions on thumbs for thumb suckers. The goal is to make the habit less appealing so the child quits.
• Dental Consultation: Regardless of age, schedule an exam with your pediatric dentist. They can assess the bite and jaw alignment. Early intervention can prevent more complex problems later. If the pediatric dentist sees any concerning shifts, they may recommend watching for natural correction or, in some cases, fitting the child with a dental appliance to guide the teeth as adult teeth come in.
• Orthodontic Treatment: For children older than about 4 years with persistent pacifier teeth, professional orthodontic treatment is often the solution. This could include braces, expanders, or other appliances to straighten teeth and reshape the jaw. The good news is that corrective treatment for pacifier induced issues is typically very successful. As Oral-B’s pediatric dentist notes, common problems from pacifiers can be “corrected with proper orthodontic treatment”. The earlier any bite issues are addressed, the simpler and shorter the treatment will usually be.

Fixing Pacifier Teeth: Step by Step

1. Wean Immediately: Gradually reducing pacifier use is crucial. Start by limiting it only to bedtime. Reward your toddler when they go without it. The sooner the pacifier is gone, the sooner teeth can shift back.
2. Use Distractions: Introduce new comfort items (like a favorite toy or blanket) or activities to replace pacifier time. Keeping your child engaged helps them forget about the pacifier.
3. Cutting the Pacifier: For stubborn cases (age ~3-4), some parents carefully snip the tip of the pacifier’s nipple. This prevents suction, so sucking on it gives no comfort, prompting the child to lose interest. Always supervise this step for safety.
4. Dental Check Ups: Keep up with regular dental visits. A pediatric dentist can give guidance tailored to your child and catch any needed correction early.
5. Orthodontic Evaluation: If misalignment persists past age 5 or 6 (when adult teeth start coming in), an orthodontist can create a treatment plan. Early orthodontic appliances can guide teeth into place and prevent complex issues.

Most importantly, remember that pacifier teeth can be fixed. While the term sounds frightening, the actual dental issues are usually mild when caught early. In fact, dental experts report that nonpermanent pacifier teeth often “self correct” once the pacifier is gone. Persistent cases are effectively managed with modern braces or aligners, giving children a healthy smile.

FAQs

Q: Do pacifiers help with teething?
A: Yes. Many babies find sucking on a pacifier soothing when they are teething. The sucking motion provides counter pressure on the gums, and a cold pacifier (for example, one kept briefly in the refrigerator) can further ease gum pain. Pacifiers don’t stop teeth from coming in, but they often help comfort babies between feedings and sleep. Always ensure the pacifier is clean and intact when offering it for teething relief.

Q: Do pacifiers ruin teeth or cause permanent damage?
A: Pacifiers themselves don’t rot teeth, but extended use can temporarily change tooth positions. If a child uses a pacifier beyond toddlerhood, the constant pressure can push teeth into new alignments. These changes are called “pacifier teeth.” However, permanent teeth aren’t at risk if the pacifier habit stops in time. Stopping use by around age 3 lets the bite often revert. In cases where pacifier use lasted too long, orthodontic treatment can correct any lingering misalignment. The key is to limit pacifier use to infancy/toddlerhood.

Q: Can pacifier teeth fix themselves when the pacifier is stopped?
A: Often, yes. If pacifier use ends early, many bite issues will self correct on their own as the child grows. Pediatric dentists note that children who quit sucking by about age 2 or 3 tend to see the teeth move back into place within a few months. For older children (4 years and up) or severe cases, self correction is less likely and orthodontic help may be needed. Regular dental check ups can confirm if natural correction is occurring or if intervention (like braces) is advisable.

Q: What is the best pacifier for my child’s teeth?
A: The “best pacifier for teeth” is one that’s used sparingly and is designed to minimize pressure on the mouth. Orthodontic pacifiers (flat or textured nipples) are often recommended because they keep the tongue and jaw in a more natural position. Make sure it’s the right size for your child’s age, and choose a one piece, BPA free silicone model. Remember that no pacifier is completely risk free even the best design should only be used occasionally. Limiting pacifier time is just as important as picking the right shape.

Conclusion

Pacifiers can be a wonderful tool for soothing infants, but parents should use them wisely. Pacifier teeth dental changes from prolonged sucking are common but largely preventable. By stopping the pacifier habit by age 2-3 and following the tips above, most children avoid long term issues. If your toddler does show signs of a shifted bite, know that many pediatric dentists say early problems often resolve on their own once the pacifier is gone. In cases where teeth don’t correct naturally, orthodontic treatment provides an effective fix.

In the end, balance is key: use pacifiers for comfort when needed, but don’t let the habit linger into the preschool years. Keep up with healthy oral habits and regular dental visits to give your child the best outcome.
