What may be recommended?

Palatal Expansion (Expanders)

A palatal expander is a fixed orthodontic appliance used to gently widen the upper jaw when it is narrow. Generally evidence shows that the most effective expansion is carried out on children between 8 to 10 years old.
Because children’s jaws are still growing, expansion at this age is safe, effective and well tolerated. Palatal expansion can help:

Correct crossbites (top teeth inside the bottom teeth)
Create space for adult teeth (if not enough space)
Eliminate displacement of the lower jaw (sliding off to one side)
Improve the bite and jaw
Early expansion can reduce the need for more complex treatment later on

Process: based off the scan taken in the mouth, we can arrange the fixed expander to be made and it take only a few minute to fit, your child is reviewed every week over 2-4 consecutive weeks and then the appliance left in the mouth for a few months for further review.

Frequently Asked Questions

What Is a Rapid Palatal Expander?

A rapid palatal expander is a custom-made orthodontic device used to gently widen the upper jaw (palate). It works by applying controlled pressure to gradually separate the two halves of the palate, creating more space for teeth to align properly. This treatment is most effective in children while the jaw is still developing.

Some adults may also require significant expansion if they have a narrow upper jaw -this is a different procedure called SARPE (Surgically Assisted Expansion), once growth is finished the main feasible method of this as an adult involves a special surgery.

What are the benefits of palatal expanders?

Choosing a palatal expander in Dublin can provide several long-term benefits:
