What is the primary purpose of a palatal expander in dental treatment?

To improve occlusion
To correct crossbites
To enhance aesthetic appearance
To increase tooth mobility

The correct answer is: To correct crossbites

The primary purpose of a palatal expander in dental treatment is to correct crossbites. A palatal expander works by gradually widening the upper jaw, specifically the palate. This expansion can create sufficient space to allow the upper teeth to align properly with the lower teeth, addressing issues such as a crossbite, where the upper teeth overlap the lower teeth on one or both sides. By providing a more balanced alignment, a palatal expander aids in achieving a functional bite, promotes better dental occlusion, and can enhance overall oral health. The expansion is typically performed over a period of time, providing a non-invasive method to correct skeletal discrepancies in the dental arch. Other options, while related to dental treatments, do not accurately encompass the primary function of the palatal expander.
