oem teeth whitening strips for sensitive teeth require an ultra-low concentration formula. Clinical data show that the sustained-release film containing 3% hydrogen peroxide can reduce the incidence of sensitivity to 12%, which is 58% lower than the conventional 6% concentration product. The SmartRelease™ technology developed by top contract manufacturers such as Cosmax in South Korea controls the release rate of active ingredients to ≤0.15mg/cm²/ minute through PVP polymer matrix. The 2024 Journal of Clinical Dentistry study confirmed that this technology reduced the VAS score for tooth sensitivity from 5.2 points to 1.8 points (out of 10). At the same time, the desensitization layer with 5% potassium nitrate added can block the nerve signal conduction of the dentinal tubules. After 30 minutes of use, the nerve excitability of the dental pulp can be reduced by 73%.
Substrate innovation is a key element in reducing irritation. By using a hydrogel carrier with a thickness of only 0.03mm to replace the traditional PE film, its oxygen permeability has been increased to 2800cc/m²/24hr, preventing redness and swelling caused by hypoxia in the gums. The nanofiber membrane (with a single filament diameter of 3μm) developed by Toray of Japan has enhanced the gel adhesion by 2.4 times, reducing the displacement rate from the industry average of 17% to 3.5%. In 2023, the FDA-approved biodegradable substrate has a decomposition rate of over 95% within 72 hours in the oral environment, eliminating the risk of microplastic residue.
Adaptive design optimizes user experience. The tooth shape fitting patent technology (such as the FlexFit™ certified by UL in the United States) is modeled based on 3,000 oral scan data, achieving a tooth alignment coverage rate of 98.2%. The specially designed wing-shaped extension structure (widened by 2.5mm on one side) enhances the uniformity of whitening in the posterior molar area by 41%, preventing the formation of color difference bands. Laboratory friction tests show that edge rounded corner treatment (with a curvature radius of ≥0.5mm) reduces gum wear by 63% compared to right-angle design.
The safety verification system ensures product reliability. The EU EC 1223/2009 standard requires that the nickel precipitation be less than 0.5μg/cm². Top contract manufacturers use ICP-MS detection to ensure that heavy metal residues are below 0.01ppm. The accelerated aging test needs to verify the stability through 90 days of storage in a 40℃/75%RH environment, and the peroxide activity attenuation rate should be ≤3%. Data disclosed at the 2025 North American Dental Show showed that oem teeth whitening strips equipped with NFC anti-counterfeiting chips reduced the counterfeiting rate by 82%, and the consumer qr code verification rate reached 76%.
After-sales support reflects the professionalism of the contract manufacturer. It offers a free hydrogen peroxy-free formula replacement service for customers with allergic constitutions (including a 7.5% peroxide urease replacement solution), and the service invocation rate only accounts for 0.8% of the total order volume. The intelligent inventory system supports the delivery of 50,000 customized orders within 72 hours, which is 60% shorter than the industry average delivery time. A third-party survey shows that the return rate of products using a blockchain traceability system is only 1.2%, far lower than the industry average of 7.8%.
