NewSmile's Extra Thick Clear Retainers — an upper and lower set built for long-term durability, crafted from heavier-gauge, BPA-free dental-grade plastic for patients who want a more robust retainer that holds up to daily wear. 75% less than Australian dental clinics. These are the right choice if you: Have broken or warped standard retainers before Wear your retainers every night without fail (heavy daily users) Do light nighttime grinding in addition to post-orthodontic retention Want a retainer that lasts longer between replacements Custom-made from your digital scan — upper and lower set delivered across Australia, no dental appointments needed. Prevents teeth shifting after braces, Invisalign®, or clear aligners Extra durable heavier-gauge material — custom-fit, nearly invisible BPA-free dental-grade plastic Replace every 6 months as material stretches with daily use Delivered across Australia Why replacements matter: teeth naturally drift back after orthodontic treatment, and jaw bone density changes as you age accelerate this shift. We recommend replacing every 6 months to maintain a precise, protective fit. Looking for standard retainers? Click here for Regular Retainers 👉 Already a NewSmile customer? click here
