The Truth About Pacifiers & Your Baby's Teeth

Pacifiers have long been a go-to soothing tool for parents and caregivers, providing comfort to fussy babies and helping them settle down for a peaceful sleep. But what exactly are the implications of pacifier use on your little one's dental health? 

Pacifiers have long been a go-to soothing tool for parents and caregivers, providing comfort to fussy babies and helping them settle down for a peaceful sleep. But what exactly are the implications of pacifier use on your little one's dental health? 

In this article, we'll uncover the truth about pacifiers and their impact on your baby's teeth. While pacifiers can offer benefits like soothing and reducing the risk of sudden infant death syndrome (SIDS), it's essential to understand the potential dental issues associated with prolonged use. 

So, let's explore the facts, discuss the right pacifier choices, and discover effective strategies for successful weaning that promotes good oral health habits for your child's future.


Pacifiers can be a lifesaver when it comes to soothing your little one. They provide a natural instinct for babies to suck, offering them a sense of comfort and security. The gentle sucking action can help calm a fussy baby and even aid in the transition from breastfeeding to bottle feeding.

But that's not all—pacifiers have also been associated with a reduced risk of sudden infant death syndrome (SIDS). Studies have shown that using a pacifier during sleep can help create a safer sleeping environment for your baby. 

However, it's crucial to use pacifiers safely and in moderation. Remember to always follow safe sleep practices and never attach the pacifier to a string or necklace.


Prolonged pacifier use can have implications for your baby's dental health, specifically in terms of teeth and jaw development. Continuous sucking on a pacifier can impact the alignment of the teeth, leading to malocclusion, a condition where the upper and lower teeth do not fit together properly. This can manifest in different ways:

  • Overbite: Prolonged pacifier use can contribute to the development of an overbite, where the upper front teeth excessively overlap the lower front teeth.
  • Crossbite: The continuous sucking motion can also lead to a crossbite, where the upper and lower teeth do not align correctly when the jaws are closed. This can occur in the front teeth (anterior crossbite) or the back teeth (posterior crossbite).
  • Open bite: Prolonged pacifier use may result in an open bite, characterized by a lack of vertical overlap between the upper and lower front teeth when the jaws are closed. This can create a visible space between the front teeth.

Extended pacifier use can significantly contribute to misalignment, causing crooked teeth or gaps between them. The shape of the palate (the roof of the mouth) can also be affected. Excessive pacifier use can narrow and heighten the palate, potentially influencing the development of the dental arches.

It's important to monitor and limit pacifier use as your baby's teeth and jaws are still developing. Regular dental check-ups and guidance from a pediatric dentist can help address any concerns and ensure proper dental alignment and development.


Choosing the right pacifier is crucial for promoting good dental health in your baby. When it comes to nipple shape, you'll find two common options: orthodontic and symmetrical. An orthodontic pacifier is designed to mimic the shape of a baby's natural sucking motion, promoting proper tongue placement and reducing the risk of dental issues. 

On the other hand, symmetrical pacifiers have a nipple shape that doesn't necessarily follow the natural contours of the mouth.

Additionally, consider the material of the pacifier. Silicone pacifiers are firm, durable, and easy to clean. They're also less likely to retain odors or flavors. Latex pacifiers, on the other hand, are softer and more flexible, but they tend to wear down more quickly.


Weaning your baby off the pacifier can be a gradual process that promotes good oral health habits. Here are some effective strategies to consider:

  • Gradual reduction: Start by limiting pacifier use to specific situations, such as sleep times or moments of distress. Gradually decrease the duration of pacifier use each day.
  • Substitution with other comforting methods: Introduce alternative soothing techniques, such as gentle rocking, singing, or providing a favorite stuffed toy or blanket for comfort.
  • Positive reinforcement: Encourage and praise your baby when they don't use the pacifier. Celebrate their progress and consider offering rewards or small treats for reaching milestones in the weaning process.

Remember, each child is different, and weaning may take time and patience. Stay consistent and be flexible with your approach. In the next section, we'll provide essential oral care tips for pacifier users to maintain their dental health during and after the weaning process.


Maintaining good oral hygiene is important for pacifier users to prevent dental issues. Here are some essential tips to keep in mind:

  • Regular cleaning: Clean the pacifier regularly by washing it with warm, soapy water. Avoid dipping it in sugary substances or your own mouth, as this can transfer harmful bacteria.
  • Introduce oral care routines: As your baby grows, start wiping their gums with a clean, damp cloth after feedings. Once teeth erupt, transition to using a soft-bristled infant toothbrush and a smear of fluoride toothpaste.
  • Schedule early dental visits: Consult a pediatric dentist early on, around the age of one, for dental check-ups and guidance on your child's oral health. Regular dental visits help monitor their dental development and address any concerns.

By following these oral care tips, you can promote a healthy mouth for your baby, even during the pacifier weaning process.
