How Do Pacifiers Affect My Child’s Teeth?


The thumb, pacifier, or another object babies feel most comfortable sucking on can soothe them when they’re not feeling well. It has been found that long-term use of pacifiers can cause serious oral health problems, including improper alignment of teeth, changes in the roof of the mouth, and tooth decay. 

To prevent dental problems associated with pacifiers, limit their use whenever possible until your child is weaned off them immediately, preferably after the first year, but no later than their fourth or fifth year.

As they progress, they are at a much higher risk for developing teeth problems that will not be self-correctable. Consequently, it may be necessary to spend a lot of money on dental treatments that could have been avoided in the future. Childrens Dentistry Las Vegas dentists understand the importance of preventive dentistry. Throughout this guide, you will find all the information you need about pacifier use, when it is appropriate to stop using them, how to limit their use, and how to wean your child from them.

What Are Pacifiers For?

A baby’s instinct to suck on something is natural and a form of self-soothing. 

As a result of pacifier use, it has many benefits, such as easing sleep, providing comfort for babies, reducing Sudden Infant Death Syndrome (SIDS), reducing pain, and soothing a crying baby.

Using a thumb-sucker is similar to using a pacifier and is used for the same purpose as using a pacifier. Despite this, thumb-sucking is less ideal, as it is known that the child’s fingernails harbor a lot of bacteria that can get into the mouth of the child and cause them to become sick. Because thumb-sucking cannot be physically removed from a child, it can also be challenging to break that habit in the future.

Even if you are weaning your child off of pacifiers, you should ensure that your child doesn’t simply replace them with thumb sucking, which can cause the same dental issues as pacifier usage.

What is the perfect time to stop giving pacifiers to your child?

As much as you can safely use pacifiers for the first year of your baby’s life, anything beyond this point no longer has a place in the baby’s life. Pacifier use doesn’t need to be completely cut off at this point, but it’s best if you wean your child off it as soon as possible.

The shape of the mouth’s roof and the teeth’ alignment may be affected when a pacifier is used for an extended period. Whether you decide to stop your child’s pacifier use depends on your preference, but they should stop using it by age four to avoid serious dental problems.

A child’s first year: A pacifier provides children with a natural soothing sensation, similar to what they might experience from breastfeeding during this first year. A pacifier can assist the baby in falling asleep and improving their feelings of relaxation.

1 to 2 years old: At the 1-year mark, the instinctual desire to suck on something to soothe yourself is not as strong, and it might be a good idea to wean a baby of it to avoid it becoming a habit at a later date.

2 to 4 years old: Children tend to discontinue using pacifiers on their own naturally. Weaning your child from the pacifier should be implemented if they do not show signs of stopping using it. 

Older than four years: Pacifiers are associated with a much higher risk of dental problems for children beyond this age.

Why Pacifiers Can Be Harmful

Several health problems are associated with using pacifiers for long periods, including problems with the mouth, teeth, skin, and social problems. In addition, pacifiers used outside of the period when your child’s teeth began to grow can cause the following problems:

  • An open bite or overbite
  • A buck’s teeth
  • A decaying tooth
  • Changes to the mouth’s roof
  • Skin irritation caused by rubbing
  • An impediment to speech
  • Problems related to eating
  • Issues of social concern
  • Tooth alignment problems

Harms of pacifiers

Pacifiers and Their Harm

There are many benefits to using a pacifier. If you feel that your child is still relatively young and the use of the pacifier has too many benefits to remove immediately, then you can make these changes to reduce harm to your child.

  • Ventilated pacifiers should be used
  • Maintain a clean environment
  • Keep it away from sweet liquids
  • Alternate comfort methods
  • Breastfeeding
  • Sippy cups can be used

A Guide to Weaning Your Child Off of Pacifiers

Life without a pacifier can be difficult when you’ve been accustomed to one since infancy, but these tips can help. Consider these options:

  • Vinegar can be dipped into the pacifier
  • Reduce satisfaction by cutting or piercing the pacifier
  • Please don’t bring it on vacation
  • Reinforce positive behavior
  • Exchange the pacifier for something else
  • Slowly reduce their use of it to wean them off of it
  • Don’t reward your child if they don’t use it


Pacifiers are great for babies during the first year of their lives, but when used regularly, they can cause more harm than good. Even though weaning off pacifiers early reduces the risk of serious oral health and social problems, taking something away from your child that helps them sleep and offers them a lot of comforts can be challenging. Using a pacifier excessively is one of the worst things you can do to your baby. The best option is to breastfeed. 

In addition to rocking your baby back and forth, you can also give them a special toy or blanket to comfort them or use white noise to relax them. Kids dentist Las Vegas believes in the importance of preventative dentistry.
