Deformed teeth and pacifiers: all about the effects of pacifiers

Teeth can be deformed by the pacifier

Pacifier, pacifier, towel, thumb or cuddly toy, the sucking reflex is innate to the baby. In the mother's womb, some fetuses already suck their thumb. After birth, this reflex allows them not only to feed themselves (at the breast, bottle) but also to reassure and calm themselves in case of need (crying, falling asleep, etc.)

As children grow up, many of them are unable to break this ingrained habit. However, the pacifier can lead to growth problems and orthodontic deformities.

In this article we talk about the long-term effects of pacifiers and give you some tips on how to help your child part with them.

Harmful effects of pacifiers 

Teeth damaged by the pacifier

Teeth can be deformed by the use of a pacifier (or other sucking device). It is important to know that in the medium and long term, the use of a pacifier can hinder the growth of milk teeth and even permanent teeth.

Here are some dental problems your child may face:

Upper or lower teeth towards the front

Deformation by the pacifier: forward teeth.

The thumb or pacifier can cause a forward pull. This has two consequences. The first is to shift the upper and lower jaws. The second is that the upper incisors come forward.  

To learn more about front teeth as a consequence of the pacifier, discover our article devoted to this subject.

Teeth that grow backwards

This is the opposite phenomenon of the teeth moving forward. Here the traction is made towards the back, causing the teeth to push in the opposite direction.

Teeth too far apart

Deformation by the teat: teeth spread.

The presence of a pacifier can prevent the teeth from being positioned correctly. It creates a space between the teeth.

Caries and other oral infections

The pacifier is usually lying around and is not necessarily disinfected as needed before each use. These microbes and bacteria that settle on the pacifier can cause oral infections such as cavities.

To avoid this problem, practice strict oral hygiene: wash and sterilize the pacifier every time it falls on the floor, don't put the pacifier in your mouth to clean it, and remember to brush your child's teeth thoroughly after every meal.

Teat: deformation of the mouth and palate

Not only can a child's teeth be deformed by the use of a pacifier, but it can also affect the positioning of the jaw. If used too often, this forward pull of the jaw during sucking hinders growth.

There are two main types of jaw deformities related to the pacifier.

The gap in the tooth

The upper and lower jaws no longer touch when the mouth is closed. A space is created between the two.
In addition to the unsightly side, the gap in the teeth can have consequences on speech and chewing.

The cross bite

A crossbite occurs when the jaws are not aligned. This misalignment of the jaw or teeth can lead to :

  • Deformities in the mouth,
  • Joint pain,
  • Chewing problems,
  • An unaestheticism.

Teeth deformed by the pacifier: how to avoid it and help your child to stop using it?

At what age should a child's pacifier be removed?

There is no guidance on the exact age at which a child should stop sucking his thumb or using a pacifier. However, dental professionals agree that it is best for a child to stop around 2 or 3 years old. For more information on this topic, see our article onage at which to remove the pacifier.

Starting school is often a good opportunity to stop using pacifiers: the child takes a step that he knows is important.

Before this age, oral deformities can still be prevented. And if they have already occurred, teeth deformed by pacifier use can still correct themselves.  

The main problem parents face when trying to get their child to stop using a pacifier is habit. Whether it's for entertainment, relaxation or sleep, the child has developed a habit of sucking his thumb or pacifier.

So, like all habits, the best thing is to try to replace it gradually by something else without rushing because banning the pacifier would only lead to misunderstanding and frustration.

The orthodontic pacifier: a solution?

Using an orthodontic teat could be a solution.

One of the preventive and corrective solutions to preserve the child's dental capital is the orthodontic pacifier. Specially designed to reduce the harmful effects on the teeth, it is an alternative to traditional pacifiers. However, it is necessary to be well informed before buying a pacifier because many so-called "orthodontic" pacifiers are not.

The orthodontic pacifier can for example be adopted from an early age. This way, the child is used to it from a very young age and growth problems are limited.

It can also be offered later to help the child separate from his thumb or pacifier.

Other possible techniques to stop the pacifier

For getting a child to stop using a pacifierThere are a multitude of tricks that can be used. Each child is different and one technique will not necessarily work for all children. The best thing to do is to follow the child's rhythm and not to make him feel guilty if he can't stop.

Help your child stop using a pacifier before his or her teeth become deformed.

Here are some examples that may help you:

  • Turn the situation into a game,
  • Distract him with other activities, when the child wants to use his pacifier out of boredom,
  • If he is old enough: make him aware of the consequences of using a pacifier,
  • Leave the pacifier at home only,
  • Read books on stopping pacifiers,
  • Offer a blanket to fall asleep,
  • Offer a hug as a guide to comfort.

If, despite your best efforts, your child cannot do without his pacifier and suffers from oral deformities, do not panic! These deformities are completely reversible with dental or orthodontic care.
