For Kids, Teens, and Adults

What is a Palatal Expander?

A palatal expander is a custom-made orthodontic device used to gradually widen the upper jaw (palate). This treatment is most effective in younger patients while the bones of the mouth are still growing. By slowly applying gentle pressure, the appliance separates the two halves of the upper jaw, encouraging natural bone growth and increasing space for permanent teeth to emerge.

How Palatal Expanders Create Space

Palatal expanders gently widen the upper jaw by applying pressure on the upper molars over time. As the expander is activated daily (usually with a small key), it gradually opens the mid-palatal suture, which hasn’t yet fused in children. This process creates more room for permanent teeth to erupt in proper alignment and improves bite function.

Resolving Crossbites and Crowding Issues

When the upper jaw is too narrow, it can lead to a crossbite—where the upper teeth sit inside the lower teeth. This can cause uneven wear, jaw discomfort, and shifting. Crowding occudfsrs when there isn’t enough space for adult teeth, which can lead to misalignment. Palatal expanders correct both issues early, reducing the need for extractions or more invasive treatments later.

Improving Breathing and Bite Alignment

A narrow upper jaw can sometimes restrict airflow through the nasal passages, contributing to mouth breathing or snoring. By widening the palate, expanders can open up the airway and promote healthier breathing habits. Additionally, improving the alignment of the upper and lower jaws supports better function, chewing, and overall facial balance.

How long do you have to wear a palatal expander?

Expansion usually takes a few weeks, but the expander typically remains in place for three to six months to allow new bone to stabilize and prevent relapse.

Will the expander affect my speech or eating?

It may take a few days to adjust, and you might notice a slight lisp or increased saliva at first. Speech and eating habits usually return to normal within a week as you get used to the expander.

What happens if I forget to turn the expander?

Consistency is important for successful results. If you miss a scheduled turn, contact our office for guidance — we may advise adjusting your schedule slightly to stay on track.

Will a gap form between my front teeth?

Yes, it’s normal for a small gap to appear between the upper front teeth during expansion. This is a sign that the expander is working correctly. The gap usually closes naturally with braces or as treatment continues.
