I’ve been using Smileflex night retainers for a month now, and I’m genuinely impressed. They fit perfectly and are incredibly comfortable to wear overnight—no more sore gums or that bulky feeling I’ve experienced with other brands. The material feels durable and high-quality, and I love that they’re nearly invisible.
This was such an easy process. Thank you to the Smileflex crew for answering all my questions and for being so easy to deal with.
Easy to understand instructions for impressions. Fast turn around and perfect fit!
The Smileflex retainers were faster to get hold of than going through a dentist for retainers, and pricing was transparent and easy-to-stomach. I appreciate not having to make purchasing decisions while someone has their hand in my mouth.
I chose the blue ones so I could tell them apart but the quality of these alone are so noticeable! They feel strong and rigid but not too stiff to be uncomfortable. They feel like they will last a long time. Very happy with this purchase.
Comfortable,good quality!!!!
The first thing I noticed was the premium feel to the retainer. I can't say enough good things about the process. So simple and easy. Extremely happy with my purchase.

Product care information
Storage instructions
Store your retainers in the provided protective case. Avoid exposure to sunlight or heat. Keep dry.
Recommended storage temperature: 5°C–35°C.
Cleaning and maintenance
It's important to maintain the cleanliness and hygiene of your retainers. Do not eat or drink while wearing the retainers.
The Smileflex® Waves™ Cleansing Pod and Smileflex® Premium Cleansing Tablets deliver the best results, removing up to 99.9% of plaque, stains, odours, bacteria and pathogens.
If you're looking for alternative cleaning options, you can also use mild soaps such as curd soap, liquid soap, or dishwashing liquid. However, avoid heavily perfumed soaps.
It's not recommended to clean dental appliances with toothpaste, mouthwash, or water hotter than 50°C. Toothpaste contains abrasive particles that can scratch surfaces, trapping bacteria and making cleaning harder. Mouthwash often contains alcohol and other chemicals that can damage or discolour your appliance over time. Both can reduce the lifespan of your appliance.
Sterilisation
A sterilisation with gas and plasma (<50°C) is possible. Due to the product's thermolability, it is not autoclavable. For daily disinfection, Smileflex® Premium Sterilising Foam removes up to 99.9% of plaque, stains, odours, bacteria and pathogens.

Frequently Asked Questions
You asked, we answered! We’ve put together some of the most commonly asked questions about our custom night 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 or other orthodontic treatment such as aligners. People prefer clear retainers because they find them to be more comfortable than traditional ones that have wires.
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.
Ours are higher quality. Our professional dental studio uses industry leading equipment, materials, and processes to create our Smileflex custom retainers.
Retainers are a different product to aligners (Invisalign). Retainers continue to keep teeth in alignment after orthodontic treatment, while aligners are used as an alternative to braces.
Both retainer products are made from copolyester, however, the density of the materials are different. Our Invisible Retainer Pro™ is recommended for day use as the material is slightly more resilient, making it easy to insert and remove frequently throughout the day for eating, drinking, speaking, etc. Our Night Retainer Max™ on the other hand, is slightly more dense to be more suitable for night-time wear.
It's recommended by orthodontists to wear 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 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 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 retainers once or twice a week while sleeping for the rest of your life.
Absolutely not. Although 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.
