Are Invisalign Retainers Supposed to be Tight?

Have you recently started Invisalign treatment and noticed your aligners were a little too snug for comfort? This is exactly the way they should feel! Let’s dive into why below!


New Invisalign Aligners and Retainers Help Guide Your Teeth 

According to Dr. Nathan Kryn, Orthodontist at NC Oral Surgery and Orthodontics, each new Invisalign aligner or retainer will initially feel tight, but not painful. They are initially snug in order to guide the teeth into their new positions established by the Invisalign aligner.

Why do my aligners feel loose over time?

After one to two weeks, the aligners may not feel as tight as they were initially and that is okay. The feeling of looseness signifies that the teeth have begun to move. Although Invisalign aligners and retainers may initially feel snug and gradually feel looser over time, they are very comfortable to wear. They also do not affect the surrounding gum tissue since they are custom-trimmed to only cover the teeth.

What materials make Invisalign retainers?

Invisalign clear aligners are made of flexible plastic, specifically, a patented thermoplastic material created exclusively for Invisalign treatment. Invisalign aligners are also FDA-approved and contain no BPA, BPS, latex, or gluten. 

Since Invisalign is created to be “invisible,” the aligners are thin, clear, and fit snugly over the teeth. This helps your teeth move slowly over time until your smile is exactly the way you planned!
