Now we dive into Part 2 of Orthodontic Appliances! Check out these different types of appliances and what they do.


Herbst Appliance

The Herbst appliance is used to correct overbites due to lack of development of the lower jaw. It is cemented in place which eliminates cooperation. Simple braces cannot achieve this correction.
The appliance can be adjusted by the orthodontist to create the ideal position of the lower jaw to the upper teeth.


A device that is used to protect your mouth from injury when you are participating in sports. The use of a mouthguard is especially important for orthodontic patients, to prevent injuries.


Palatal Expander

A palatal expander, also known as a rapid palatal expander, rapid maxillary expansion appliance, palate expander or orthodontic expander, is used to widen the upper jaw so that the upper and lower teeth will fit together better.



A gadget that the orthodontist gives you to wear after your braces are removed. The retainer attaches to your upper and / or lower teeth and holds them in the correct position while your jaw hardens and your teeth get strongly attached to your jaw. At first, you wear the retainer 24 hours a day, and then only at night.


Lower Lingual Holding Arch

This gadget is used to hold spaces for before permanent/adult teeth come in.
