Once treatment is complete, a retainer is worn for a period of time, usually just at night. The retainer helps maintain the new smile and also allows for small adjustments, if needed, once the braces have been removed.
Your orthodontist will go over the options with you and provide specific instructions on the use of your retainers.
PED (Palatal Expander Device)
Both removable and fixed PEDs can be used to address crowding and other issues by expanding the upper jaw to make more room to accommodate tooth movement and/or jaw alignments.
