About Smile Aligners

Smile Aligners Ltd is a UK-based provider of at-home clear aligner treatment, operating from London. The company offers custom-made, dentist-approved clear aligners designed to straighten teeth without traditional metal braces. Customers can choose between day-time aligners, worn for around 22 hours a day over roughly three to five months, or night-time aligners, worn for around ten hours while sleeping over roughly five to seven months. Treatment can be started either by visiting one of the brand's affiliated scan centres across the UK for a 3D scan or by ordering an at-home impression kit. The company also provides retainers, a range of educational pages covering conditions such as crowding, crossbite, deep bite, and spacing, and support through a Smile Specialist team who review each case before treatment begins.

Does Smile Aligners offer a welcome discount for new customers?

New visitors to the site are offered a percentage discount on their first order, presented through a sign-up prompt on the website. This is aimed at customers who are visiting for the first time and considering starting a treatment plan.

Is there a student discount available?

Smile Aligners provides a dedicated discount for students, offering a set reduction on clear aligner treatment for those who can show valid student identification. This is presented as part of the brand's effort to make treatment more accessible for people on a limited budget.

Are discounts available for military personnel or NHS and public sector workers?

A separate discount is offered to active and retired members of the armed forces, presented as a token of appreciation for their service. In addition, a discount is available for Blue Light Card holders, a scheme generally associated with NHS staff, emergency services, and social care workers. Both discounts require some form of verification before they can be applied.

Does Smile Aligners have a referral scheme?

The brand runs a "refer and earn" programme, allowing existing customers to share a unique referral link with friends. Once a referred friend begins their own aligner treatment and their order is completed, the referrer receives a reward. This is designed to benefit both existing customers and newcomers to the brand.

Is there a loyalty scheme for returning customers?

Based on available information, no formal points-based or tiered loyalty scheme is currently advertised. Ongoing incentives instead appear to be structured around the referral programme and periodic seasonal promotions rather than a dedicated loyalty programme.

Does Smile Aligners offer free delivery?

Aligners and impression kits are delivered directly to the customer's home as part of the standard ordering process. The website does not clearly state a specific delivery fee structure beyond this, so customers who want confirmation on delivery costs for their exact order are best placed to check details at checkout or contact customer support directly.

What are the benefits of signing up to the newsletter or mailing list?

Visitors who submit their email address through the website's sign-up form are offered a discount on their first order, as noted above. This appears to be the primary incentive currently linked to joining the mailing list.

Does Smile Aligners run seasonal promotions?

The brand has featured a Christmas-themed promotional banner on its website, encouraging customers to begin treatment in time for the festive season. As with other seasonal campaigns across many retailers, the specific terms and availability of such offers can change, so current details are best confirmed directly on the website at the time of purchase.

What guarantee does Smile Aligners provide?

The company offers a guarantee for customers who are assessed as unsuitable for treatment. If, after reviewing a customer's impressions or scans, the Smile Specialist team determines that clear aligner treatment is not the right option, a refund is provided. Full terms are set out in the brand's refund policy page.
