What Makes Clear Aligners Ideal for Adults?

How the Process Works (and Why It Matters)

When researching the best clear aligners for adults Europe residents can access, understanding the process is critical.

Step 1 – Online Assessment

Most providers, including Smileie, begin with an online assessment or eligibility survey to determine if you’re a suitable candidate for remote orthodontic treatment.

Step 2 – Impression Kit at Home

You receive an impression kit (available in the Shop along with chewies, aligner cleaner, and aligner case) to create moulds of your teeth from home.

Step 3 – Digital Treatment Plan

A customised treatment plan shows how your teeth will move for smile correction, spacing, or crowding adjustments.

Step 4 – Aligner Delivery & Monitoring

Your aligner trays are delivered to your home, with progress tracked through dental monitoring.
