Byte Aligners Shut Down: What Happened & Best Alternatives for 2026

By Joanna M.

What Happened to Byte? The Full Story

Byte was one of the fastest-growing direct-to-consumer aligner brands in the US market. Founded in 2017 and acquired by Dentsply Sirona in 2021 for roughly $1 billion, Byte attracted hundreds of thousands of customers with its HyperByte vibration device and aggressive marketing that promised fast results without visiting a dentist.

The cracks started showing well before the company closed. Byte faced mounting complaints from customers who reported tooth movement without adequate clinical oversight, bite changes, and difficulty getting refunds or replacement aligners when treatment went wrong.

On the regulatory front, the FDA issued a Class II recall of Byte's HyperByte device in 2023, citing concerns about how the vibration technology was being marketed relative to its cleared indications. That recall — combined with a broader Federal Trade Commission inquiry into the at-home aligner industry — put serious pressure on the brand.

Dentsply Sirona ultimately decided Byte was not worth saving. The company wound down Byte's operations in late 2024. The customer portal was shut off. Replacement retainer requests stopped being fulfilled. Support lines went dark. Customers who had paid in full — including many still mid-treatment — were left with no path forward.

Why Did Byte Shut Down?

• Parent company pressure: Dentsply Sirona faced corporate turmoil including leadership changes and restructuring. Byte was a non-core asset that had become a liability.
• Regulatory scrutiny: The FDA recall of HyperByte and heightened oversight of the at-home aligner category made Byte's core product proposition harder to defend.
• Consumer complaints at scale: Thousands of customer complaints — ranging from incomplete treatment to unexpected dental damage — created significant legal and reputational exposure.
• Unsustainable unit economics: Like many DTC health brands of the 2017–2022 era, Byte was built on aggressive customer acquisition costs. When growth slowed and refund rates climbed, the model broke.

What Should Byte Customers Do Right Now?

1. Contact your bank or credit card company. If you paid for a treatment plan that was never completed, you may be eligible for a chargeback. Act quickly — most card issuers have time limits on disputes.
2. See a local orthodontist or dentist. If your teeth shifted unexpectedly during Byte treatment, get a professional evaluation before continuing with any other aligner brand.
3. Replace your retainers. After any aligner treatment, retainers hold your results. If Byte was your provider and your retainers are worn out or lost, you need replacements.
4. Document everything. Save your Byte purchase confirmation, treatment photos, and correspondence. Class action lawsuits related to Byte shutting down have been filed.

How to Replace Your Byte Retainers in 2026

Here is what to look for in a provider:

• Fresh impression or scan intake: A good provider takes an accurate mold or 3D scan of your current teeth — not your old Byte records.
• Licensed dental oversight: The retainer should be reviewed by a licensed dental professional before it ships.
• Transparent pricing: Some providers lock you into subscription billing without making it clear upfront.
• Ongoing access: Retainers crack, warp, and get lost. You want a provider who will still be around — unlike Byte.

NewSmile's Retainer Club covers all of these. You start with an at-home impression kit, a licensed dentist reviews your case, and your custom retainer ships as soon as production is complete. No subscription traps, no disappearing portals.

If you grind your teeth at night, consider adding a custom night guard to protect your post-treatment results.

Why NewSmile Is the Best Byte Alternative in 2026

• Fresh impression, not old records: NewSmile takes a new impression of your teeth as they are today — important because teeth move after Byte treatment ends.
• Transparent $99 pricing: No guessing, no hidden fees. One price for a pair of custom Essix retainers.
• Retainer Club for ongoing access: If your retainer breaks or gets lost, NewSmile is still there. Byte customers learned what happens when a provider disappears.
• No regulatory baggage: No FDA recalls, no FTC inquiries, no class action history.
• Night guard option: A custom night guard protects your investment if you grind at night.

FAQ

Can I still use my Byte retainer?

If your Byte retainer still fits well and is not cracked or warped, you can continue using it. Plastic retainers typically last one to three years with regular use. If yours is older, loose-fitting, or visibly damaged, replace it promptly to prevent teeth from shifting back.

How do I replace my Byte retainer now that Byte is closed?

You need a new provider. Take impressions of your current teeth and submit them to a dental lab. NewSmile's at-home retainer process is available across the US without an office visit and uses a fresh impression rather than your old Byte records.

Is NewSmile better than Byte was?

For retainers specifically, yes. NewSmile offers a dedicated retainer replacement program at a transparent price with licensed dental oversight. Byte's core product was aligners and retainers were an afterthought. NewSmile built its entire model around retainers and maintenance.

Did Byte shut down because of the FDA recall?

The FDA Class II recall of the HyperByte device in 2023 was a significant factor, but the shutdown was ultimately a business decision by parent company Dentsply Sirona. The recall, sustained consumer complaints, FTC scrutiny, and Dentsply's corporate restructuring collectively made continuing Byte operations untenable.

Will there be a class action lawsuit against Byte?

Class action lawsuits related to Byte's closure and treatment outcomes have been filed in multiple jurisdictions. If you were a Byte customer who did not complete treatment or experienced unexpected dental changes, consult a consumer protection attorney in your state.
