Can you eat normally whilst wearing expander braces?

With limitations: Whether you are referring to a palatal expander or braces that create arch expansion, there are specific food limitations that your orthodontist will review with you to prevent appliance breakage and/or trapping food debris under appliances that could lead to gingival inflammation and discomfort.

With some changes: Eating is the same, just need to avoid real sticky foods that could pull it off.
