Description

Custom Clear Retainers — Keep the Smile You Paid For

You spent months (and a lot of money) straightening your teeth. A custom retainer is what keeps them that way. Ours are made from your own impressions in FDA-cleared, BPA-free material and shipped to your door — two retainers for $149 (just $75 each), versus the $150–$300+ per retainer most orthodontists charge.

Why you need a retainer

After braces or aligners, teeth naturally try to drift back to their old positions — orthodontists call it “relapse.” A retainer holds everything in place while the bone and tissue around your teeth stabilize, protecting the results you worked for.

How it works — 3 simple steps

  1. Order your kit. We mail you an impression kit with trays, putty, a backup set, and a prepaid return mailer.
  2. Take your impressions at home using our step-by-step guide and how-to video, then mail them back free.
  3. We craft & ship. Our lab fabricates your custom retainers from your exact impressions and delivers them to your door in a few days.

How Oki custom retainers work in three steps

Choose your thickness

1.0 mm
Lowest profile and most “invisible” feel — ideal for comfortable nightly wear with minimal bulk.
1.5 mm
Extra durability and shape retention — best if you clench occasionally or want longer wear life.

Upper, lower, or both?

Follow your orthodontist’s guidance. Many people wear both arches right after treatment, then shift to nighttime wear. Choosing one arch? Pick the one most at risk of shifting — often the lower front teeth. Consistency matters most.

What’s in your kit

  • Three tray sizes + two putty sets (one backup)
  • Prepaid return mailer & step-by-step guide
  • Access to our how-to impression video
  • Two finished custom retainers, made in the USA

Care & when to replace

  • Rinse after each use; brush gently with a soft brush and mild soap (avoid abrasive toothpaste).
  • Let them dry and store in a ventilated case; keep away from heat — hot water can warp them.
  • Avoid harsh chemicals and colored mouthwashes that can stain.
  • Replace if you see cracks, warping, looseness, or if teeth feel “tight” going in.

FAQ

Are these as good as my orthodontist’s retainer?
They’re made from your own impressions in the same type of clear, dental-grade material — at a fraction of the price.

Can a retainer fix grinding?
No — retainers maintain alignment. If you grind or clench, see our custom night guards.

How long do they last?
With good care, typically a year or more. Because you get two, you always have a backup ready.

What if the fit isn’t right?
You’re covered by our 60-night guarantee — free replacement or full refund.

  1. Joey Huang (verified owner) –

    I needed to replace my retainer and I didn’t want to go back to the orthodontist because it was very expensive. I decided to try ordering a custom one online. I was a little nervous at first, but Oki turned out to be an amazing find.
    The impression kit came with clear instructions and was very easy to use. After I sent it back, they actually emailed me to confirm they have received it and even explained that everything looks good before creating the retainer. I really appreciate the attention to detail and the care of the process.
    When I received the finished product, I was surprised how well it fit that there were no tight spots and no discomfort. It feels exactly like the one I used to have from my orthodontist, but this one cost me way less and was done entirely by mail.
    I’ve been wearing it every night for a month now and it is keeping my teeth in place. It’s comfortable, clear, and very well made.
    If you’re looking for a custom retainer and don’t want to spend a fortune, I highly recommend Oki. They’re professional, fast, and clearly care about getting it right.
