Extra Thick Custom Clear Retainers — an upper and lower set built for long-term durability, crafted from heavier-gauge, BPA-free dental-grade plastic for patients who want a more robust retainer that holds up to daily wear. Up to 75% less than in-office retainers.

These are the right choice if you:

• Have broken or warped standard retainers before
• Wear retainers every night without fail (heavy daily users)
• Do light nighttime grinding in addition to post-orthodontic retention
• Want a retainer that lasts longer between replacements

Each set includes upper and lower retainers plus a home impression kit for a precise, custom fit — no dentist visit needed.

• Prevents teeth shifting after braces, Invisalign®, or clear aligners
• Custom-fit, nearly invisible, and comfortable
• Extra durable, heavier-gauge material
• BPA-free dental-grade plastic
• HSA/FSA eligible
• Fast U.S. shipping and support

Why replacements matter: teeth naturally tend to shift back after orthodontic movement, and bone density changes in the jaw as you age accelerate drift. We recommend replacing retainers every 6 months as the material stretches and wears with daily use. Wear as instructed for life.
