Expanders can be removable or fixed to the teeth and can be for either jaw but are usually for the top teeth. When patients are young, we can use an expander to change the shape of the top jaw, rather than just moving the teeth. Expanders widen the jaw, improve the bite and provide room for developing teeth.
