Why Kids Need Palate Expanders and How They Work

A palate expander is a special little tool made out of metal and plastic, shaped to fit snugly in the roof of the mouth. It’s mostly used for kids, as their jaws are still growing. The work of a palate expander is to make the upper jaw a bit wider, making more room for the permanent teeth to grow in, or helping the top and bottom teeth fit together better.

Imagine the expander as a tiny, friendly robot. It puts a gentle nudge on the two sides of the upper jaw, slowly helping them move apart. This gentle and slight push causes the jaw to create new bone, making the upper jaw wider over time. It’s quite an amazing process!

Why Some Kids Vomit

Like I’ve said earlier, a palate expander can cause a kid to vomit. This isn’t super common, but it actually happens. This might be because the expander feels strange and new in the mouth and may tickle the gag reflex, causing a kid to throw up. It might also be because the whole process feels a bit scary and stressful, which can make a kid’s tummy upset.

Just like some kids love the excitement of a roller coaster ride and others feel sick to their stomachs, the reaction to a palate expander can vary. Some might only feel sick right after the expander is put in or adjusted, while others might feel upset for a few days as they get used to the expander.
