NewSmile's Custom Clear Retainers — an upper and lower set custom-made from your digital scan, crafted from BPA-free, dental-grade thermoplastic. Maintain the straighter smile you've achieved for 75% less than Australian dental clinics. Your teeth are continually shifting as you age due to bone density changes in your jaw, and teeth have a strong tendency to relapse after orthodontic movement — even years after treatment. A custom retainer worn nightly is the only way to permanently protect your results. Prevents teeth shifting after braces, Invisalign®, or clear aligners Upper and lower set — custom-made from your digital scan Dental-grade, BPA-free thermoplastic — nearly invisible 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. Wear as directed for life. Need extra durability?
