Have you lost or broken your orthodontic retainers? Or recently had your braces removed? Keep your teeth from moving at a fraction of dentist prices! Your custom clear retainers are made right here in Australia by our Smileflex dental technicians. Choose either an upper or lower retainer, or save by selecting the combined option.

Retainers are a different product to aligners (Invisalign). Retainers continue to keep teeth in alignment after braces, while aligners are used as an alternative to braces.

Frequently Asked Questions

You asked, we answered! We’ve put together some of the most commonly asked questions about our custom clear retainers. If you can't find the answers you're looking for below, head over to the Smileflex Help Centre for even more information.

A custom retainer is a thermoformed device created specifically to fit your mouth and is worn to continue to keep teeth straight after braces. People prefer clear retainers because they find them to be more comfortable than traditional ones, and can be worn throughout the day without any wires showing.

After your braces are removed, teeth have the tendency to move back towards their previous position because the ligaments attached need time to heal. A custom retainer prevents the elasticity of the ligaments from moving your teeth, and allows time for your jaw bones to solidify around them.

They are the same. Our professional dental studio uses the same equipment, materials, and processes to create our Smileflex custom retainers. In fact, dentists have been our clients before we began offering our Impression Kit to use at home.

Retainers are a different product to aligner products such as Invisalign. Retainers continue to keep teeth in alignment after braces, while aligners are used as an alternative to braces.

It's recommended to wear your retainers at least 12 hours every day for the first 8 weeks following the completion of your orthodontic treatment. Thereafter, and approval from your orthodontist, you can begin wearing your retainers at night only for at least a year. Wearing them more often is never a bad idea, as long as you take them out to eat and clean them regularly.

If you find your retainers feel tight when putting them on, it can be a sign that your teeth are shifting while your retainers are out, and you might need to start wearing them more frequently. It's also recommended by orthodontists to continue to wear your retainers once or twice a week while sleeping for the rest of your life.

Absolutely not. Although clear retainers are custom-fitted to the mouth, they are cut differently and are not made with a spacer on the front side of the teeth to allow for gel. Retainers are made to fit close to the teeth and gums, and using them as whitening trays would push the gel out of the tray into the mouth.
