Once the Active Phase of your Orthodontic treatment is completed, your orthodontic appliances will be removed.
That is when the Retention Phase starts. This Phase is crucial. When your braces come off, your teeth go through a natural settling process for about 9-12 months. The stability of your orthodontic results depends on diligent retainer wear. Usually, your retainers are to be worn all day and all night, only to be removed when eating or brushing. Be smart! Protect all the hard work you've put into your orthodontic treatment.
Remember to remove your retainer before brushing, and brush your retainer before placing it back in your mouth.
