Young children or their parents sometimes have concerns about the comfort of the traditional expansion process involving separators followed by placement of metal expanders with sour tasting glue. Previously available alternatives such as full time retainer-style expanders are similarly bulky on the roof of the mouth, influencing speech and swallowing, at least in the short term.
For all of these options, removing food trapped between the roof of the mouth and the appliance at mealtimes is a lifestyle change for patients until the completion of active treatment with the expanders. Additionally, braces on the upper and/or lower front teeth are recommended or requested to address the alignment. As with the expanders, patients need to be careful to avoid hard/sticky foods and to spend extra time on oral hygiene.
