Does My Child Need Palate Expanders? - What You Need To Know As A Parent

August 10, 2023

The use of palate expanders in pediatric dentistry is a topic of interest and concern for many parents. Palate expanders are orthodontic devices designed to widen the upper jaw in order to correct certain dental issues.

However, the decision to use a palate expander for a child should not be taken lightly, as it requires careful consideration of the child's individual needs and dental health. 

This article aims to provide parents with an objective and comprehensive understanding of palate expanders, including their function, indications, benefits, and potential risks.

By presenting the available evidence and discussing the various factors to consider, parents can make informed decisions regarding the need for palate expanders in their child's dental treatment. Understanding the implications of using palate expanders is crucial for parents who seek to prioritize their child's oral health and overall well-being.

What is a Palate Expander and How Does it Work?

A palate expander – also known as a palatial or jaw expander – is a dental device used to widen the upper jaw and create more space for permanent teeth, promoting proper alignment and reducing the need for future orthodontic interventions. 

This device is typically recommended for children who have narrow upper jaws or overcrowded teeth, as it can help to address these issues at an early stage.

The palate expander works by applying gentle pressure on the upper jaw bones, gradually widening the arch and creating more space. It consists of a metal framework that is custom-made to fit the child's mouth and is attached to the molars using bands or cemented brackets. The expander is activated by turning a screw or key, which gradually widens the device over a period of several weeks or months.

During the expansion process, the child may experience some discomfort, but this can usually be managed with over-the-counter pain relievers. The device may also cause temporary changes in speech, such as lisping or difficulty pronouncing certain sounds, but these typically resolve once the treatment is complete.

It is important for parents to closely follow the orthodontist's instructions regarding the use and maintenance of the palate expander. Regular check-ups are necessary to monitor progress and make any necessary adjustments.

Signs and Symptoms that Indicate the Need for a Palate Expander

An indication that a child may require a palate expander is the presence of a narrow or constricted palate. This can be observed through certain signs and symptoms.

One such sign is a crossbite, where the upper teeth are positioned inside the lower teeth when the child bites down.

Another sign is a crowded or crooked set of teeth, which can be caused by the lack of sufficient space in the mouth due to a narrow palate.

Additionally, children with a narrow palate may experience difficulty breathing through their nose, as the restricted space can obstruct the airway.

They may also exhibit speech problems, such as a lisp or difficulty pronouncing certain sounds, as the restricted palate can affect the movement of the tongue and interfere with proper articulation.

Furthermore, a child with a narrow palate may have a higher risk of developing dental issues, such as cavities or gum disease, as the overcrowded teeth can be more difficult to clean effectively.

Therefore, if a child displays any of these signs or symptoms, it may be necessary to consider a palate expander as part of their orthodontic treatment.


Benefits of Palate Expanders for Children's Dental Health

Palate expanders offer significant advantages for improving children's dental health. These dental appliances are designed to widen the upper jaw and correct certain dental issues related to a narrow palate. 

By expanding the palate, these devices can create more space for teeth to grow properly and align the upper and lower jaws for a more balanced bite.

One of the key benefits of palate expanders is that they can prevent or minimize the need for more invasive orthodontic treatments later in life. By addressing the issue of a narrow palate early on, palate expanders can potentially eliminate the need for tooth extractions or jaw surgery in the future.

Palate expanders also play a crucial role in improving children's breathing and sleep quality. A narrow palate can contribute to airway obstruction and lead to issues such as snoring, sleep apnea, and difficulty breathing during sleep. By widening the upper jaw, palate expanders can help open up the airway, promote proper nasal breathing, and reduce the risk of these breathing-related problems.

Furthermore, palate expanders can enhance facial aesthetics by creating a wider and more harmonious smile. In addition to improving dental health, a properly expanded palate can contribute to a more balanced facial appearance and boost a child's self-esteem.

In general, palatial expanders can prevent the need for invasive treatments, improve breathing and sleep quality, and enhance facial aesthetics. Consulting with a dental professional can help determine if a child would benefit from a palate expander.

Potential Risks and Considerations for Palate Expanders

When considering the use of palate expanders, it is important to be aware of the potential risks and factors that should be taken into consideration.

One potential risk is discomfort and pain. Palate expanders work by applying pressure to the upper jaw, which can cause some discomfort and soreness. However, this discomfort is usually temporary and can be managed with over-the-counter pain relievers.

Another risk is the potential for damage to the teeth and gums. If the palate expander is not properly fitted or adjusted, it can cause irritation to the gums and even damage to the teeth. It is crucial for parents to closely monitor their child's oral health during the use of a palate expander and report any concerns to their orthodontist.

Additionally, palate expanders require regular adjustments, usually every few weeks. This can be inconvenient for both the child and the parents, as frequent orthodontic visits may be necessary.


Understanding whether your child needs a palate expander can seem challenging, but being informed about what they are, why they're used, and the signs to look for can greatly simplify the process. Palate expanders can make a significant difference in your child's oral health, helping prevent complex orthodontic issues down the line, improving their breathing, and even enhancing their facial symmetry.
