At Great Marsh Pediatric Dentistry, we understand that decisions about your child’s health can feel overwhelming. One question we often hear from parents is whether pacifiers are helping or hurting their baby’s teeth. Pacifiers can be a source of great comfort for your little one, but they also come with potential dental implications. Let's explore the benefits, risks, and practical tips for using pacifiers to help you make informed choices for your child.

The Benefits of Pacifiers 

Pacifiers are more than just a way to soothe your baby—they can actually provide surprising benefits that go beyond keeping them calm.

1. Comfort and Security

Pacifiers are often a baby’s first source of comfort. The sucking reflex is natural and calming for infants, which is why many babies take to pacifiers so quickly. Whether it’s soothing a fussy newborn or helping ease them into sleep, pacifiers can be a helpful tool for parents trying to meet their baby’s emotional needs.

2. Sudden Infant Death Syndrome (SIDS) Risk Reduction

Some studies have found that pacifier use during sleep is linked to a lower risk of Sudden Infant Death Syndrome (SIDS). While the reasons aren’t fully understood, the American Academy of Pediatrics suggests that pacifiers may help by promoting lighter sleep or improving airway positioning.

3. Non-Nutritive Sucking

Pacifiers provide a safe outlet for non-nutritive sucking, which can satisfy your baby’s instinct to suck even when they’re not hungry. This can help reduce their reliance on thumb-sucking, which may pose greater challenges for maintaining healthy teeth later on.

The Potential Risks of Pacifiers

While pacifiers can be a lifesaver in many situations, they are not without potential downsides. It’s important to balance the benefits with an understanding of their risks.

1. Dental Alignment Issues

Prolonged use of pacifiers, especially beyond age 18 months, can affect the natural alignment of your baby’s teeth. Over time, this might lead to an open bite or crossbite, as the repeated pressure shifts teeth and jaws out of their optimal position.

2. Increased Risk of Ear Infections.

Pacifier use beyond 6 months is associated with increased risk of otitis media (aka ear infections).  If your little one seems prone to ear infections, weaning the pacifier in the second six months of life can be greatly beneficial.

3. Hygiene and Sanitation Concerns

Pacifiers are prone to gathering germs and dirt, which can expose babies to risk of infections. Regular cleaning and sterilization is essential, and parents must be vigilant, especially when babies drop pacifiers in less-than-clean environments.

Best Practices for Pacifier Use

If you decide to use a pacifier, adopting a balanced approach can help you reap the benefits while minimizing any potential harm to your baby’s oral health. Here are some tips to keep pacifier use safe and healthy.

1. Choose Orthodontic Pacifiers

Orthodontic pacifiers are designed to support the natural development of your baby’s teeth and jaw. They have a flatter design that creates less pressure on developing gums and teeth, reducing the risk of alignment issues.

2. Set Limits on Use

We recommend keeping pacifier use limited to key moments, such as soothing your little one at bedtime or during a particularly fussy spell. Begin to gradually phase out pacifier use after your baby turns one, aiming to eliminate it entirely by age 18 months to avoid long-term dental effects.

3. Keep It Clean

Wash pacifiers regularly with warm, soapy water and inspect them for signs of wear and tear. Replace pacifiers often to ensure your baby isn’t using a damaged or unsafe product.

4. Encourage Other Comfort Techniques

As your baby grows, introduce other comfort techniques, such as cuddling with a soft toy or listening to gentle music, to help reduce their reliance on the pacifier.

Frequently Asked Questions

What are the long-term effects of pacifier use on teeth?

Prolonged pacifier use—especially beyond age 18 months—can lead to dental alignment issues such as open bites or crossbites. To prevent this, it’s best to limit pacifier use early and plan for gradual weaning before your baby’s second birthday.

How do I help my child transition away from pacifiers?

Transitioning away from pacifiers can take time and patience. Start by limiting use to specific times, like bedtime only. Gradually reduce availability, and offer alternative soothing methods such as a favorite blanket or calming bedtime routine. For older toddlers, involving them in the process (e.g., donating their pacifiers to “other babies in need”) can make parting easier. You can also have the “Paci Fairy” visit and swap the pacifiers for a toy or go to Build-A-Bear and put the pacifier inside the bear.

Conclusion

Pacifiers can be a wonderfully helpful tool when used thoughtfully, offering comfort and even helping to promote safer sleep. At the same time, long-term use can impact your baby’s developing teeth and jaw alignment. By staying informed and adopting healthy habits, you can protect your child’s smile while meeting their needs.
