Q: What is an expander and why is it used?

A: An expander helps coordinate the alignment of the upper and lower jaw to correct cross bites. The orthodontist may also suggest an expander to widen the upper jaw and This will allow more space for permanent teeth to erupt, which avoids possible impactions of teeth (view expander video). Dr. Azar will evaluate your child’s case to see if an expander will help with treatment.
