Everyone's Weighing In on the Pacifier — Here's What Actually Affects Their Teeth

You’re at the playground when another parent asks, “Does your little one still use a pacifier?” Before you can answer, someone else has an opinion about when kids should stop, which pacifier is best, or whether pacifiers can really change teeth. Suddenly, a simple pacifier feels like a very big decision!

You don’t need to listen to every opinion you hear. At All Smiles Orthodontics & Children’s Dentistry, we help families understand what actually matters when it comes to your child’s developing smile.

Is Pacifier Use Bad for Teeth?

Not necessarily. Pacifiers can help babies soothe themselves, and the American Academy of Pediatric Dentistry (AAPD) recognizes potential benefits during infancy. The bigger concern is prolonged pacifier use as your child’s mouth and teeth develop.

Think of it this way: Your child’s teeth and jaw are constantly growing and changing. A pacifier puts gentle pressure in the mouth. If that pressure continues for a long time, it can influence how the teeth and jaws develop.

What Actually Matters?

It’s less about whether your child uses a pacifier and more about how often, how strongly, and for how long they use it.

Here are the biggest factors:

  • Age — As children get older, their developing teeth and jaws become more important to consider.
  • Duration — Using a pacifier for an extended period can increase the chance of bite changes.
  • Frequency — A child who uses a pacifier all day puts their teeth under more continuous pressure than a child who uses it only occasionally.
  • Intensity — Strong or persistent sucking can have a greater effect on the developing mouth.

Your child’s individual development: Every smile grows differently, so your child’s dentist can help you understand what’s happening in their mouth.

Prolonged sucking habits can contribute to concerns, such as an open bite or crossbite, where the teeth don't come together as they should.

So, When Should You Start Weaning?

There isn't one magic day when every child must give up their pacifier. The AAPD encourages families to work toward discontinuing nonnutritive sucking habits by around age 3, while limiting prolonged use earlier can help reduce the risk of developing bite changes.

If your little one still loves their pacifier, don't panic! Start by gradually limiting when they use it. You might save it for naps, bedtime, or especially comforting moments. And remember, you don't have to figure it out alone.
