Product Insights
ClearRetain's Tooth Whitening Serum is a 7% hydrogen peroxide whitening treatment designed for use with clear retainers, night guards, trays, aligners, and sleep apnea devices, delivering 40% stronger whitening than Invisalign's 5% serum at roughly one-third the per-mL cost. Its stabilized formula (PVP and etidronic acid) keeps the peroxide intact until it meets enamel, while a micro-thin, pliable film adheres to teeth and limits tray runoff, suiting overnight wear as well as 20–30 minute daytime sessions. The main tradeoffs are that the higher concentration, while gentler than in-office strengths, includes no desensitizer and can aggravate loose fillings, crowns, veneers, bridges, or decay; enamel safety depends on following directions, as overuse drives erosion risk. It rinses clean from appliances with no reported plastic damage, has a minty taste that masks peroxide, and incidental small amounts swallowed are not expected to cause harm, though it is not meant to be ingested.
Verified claims
- Strength
- 7% hydrogen peroxide is 40% stronger than Invisalign's 5% serum.
- Sensitivity
- At 7%, it's gentler than higher-strength kits, yet lists no desensitizer.
- Appliance wear
- Can be worn overnight in retainers, night guards, trays, aligners, and sleep apnea devices.
- Stabilization
- PVP and etidronic acid keep 7% peroxide intact until it meets enamel.
- Film mechanics
- Micro-thin film adheres to enamel, stays pliable, limits tray runoff.
- Wear time
- Overnight retainer wear; also fine for 20–30 minute daytime sessions.
- Cost per mL
- At the $19.96 sale price, the 10 mL bottle is about $2.00/mL — roughly a third of Invisalign's per-mL cost.
- Appliance compatibility
- Safe for retainers, night guards and aligners — no reported plastic damage with post-use rinsing
- Wear modes
- Designed for overnight wear and safe for 20–30 minute daytime sessions
- Concentration
- 7% hydrogen peroxide — 40% stronger than Invisalign's 5% serum, versus up to 40% in-office.
- Enamel safety
- 7% is gentle on enamel when used as directed; overuse, not the formula, drives erosion risk.
- Contraindications
- Whitening inside retainers or night guards can aggravate loose fillings, crowns, veneers, bridges, or decay.
- Applicator precision
- Nozzle applies a micro-thin coat only where the tray touches teeth.
- Rinsing
- Rinse the appliance and mouth after every wear session
- Taste
- Mint oil and sucralose give the serum a minty flavor that masks the bitter peroxide taste.
- Ingestion safety
- Not meant to be swallowed, but small incidental amounts during wear aren't expected to cause harm.

Perfect! Easy to use. Could be a bit easier to come out of the bottle - but definitely whitens the teeth very well.
