Retention
After orthodontic treatment, teeth will start falling back and to avoid that happening retention is necessary.
Essix
Essix is a see-through retention appliance and is used after wearing braces.
Essix is usually worn 1-2 days straight and after that only at night. The Essix has to be removed and put in a box when eating or brushing your teeth.
For maintaining the ideal final result, using a retainer for the whole life period is often recommended.
When the Essix brakes or gets lost, it is necessary to turn to your doctor for a new appliance.
