Why replacements matter: retainers are worn for life because teeth naturally tend to move over time. As we age, changes in jaw bone density and soft tissues can cause drift, and teeth also tend to relapse after orthodontic movement. Maintain the straighter smile you’ve achieved for less than clinics. Click here for Extra Thick Retainers
Replacement cadence: we recommend changing retainers every 6 months (materials can stretch and wear with daily use). Wear your retainers as instructed for life to keep teeth from shifting back.
