The global teeth whitening market was valued at over 7.4 billion US dollars in 2023, with a stable compound annual growth rate of more than 5.2%. Among them, the demand for specialized whitening strips for people with sensitive teeth has significantly increased, accounting for approximately 25% of the segmented market share. Professional oral care brands such as Crest under Procter & Gamble and Colgate have taken the lead in the field of sensitive teeth whitening strips by continuously investing in research and development, spending over 100 million US dollars annually on product innovation. For instance, Crest’s Sensitive White series achieved sales of over 380 million US dollars in the North American market in 2022. Its core patented technology can effectively increase the occlusion rate of dentin tubules to 92%, significantly reducing the incidence of sensitive reactions. A clinical study involving 5,000 users showed that after using this series of products, 78% of users with mild tooth sensitivity reported a reduction of more than 50% in discomfort.
Top sensitive teeth whitening strips manufacturers generally use low-concentration hydrogen peroxide formulations (usually controlled between 5% and 10%), and add desensitizing components such as 0.5%-2% potassium nitrate or stannous fluoride. Take Colgate Sensitive Pro-Relief whitening patches as an example. Its hydrogen peroxide concentration is precisely maintained at 6%, and the pH value is stable within the neutral range of 6.8-7.2 to avoid stimulating the dental pulp nerve. The product thickness is strictly controlled within 0.1 to 0.15 millimeters to ensure that the adhesion error is less than 0.02 millimeters. Third-party laboratory test data in 2023 shows that this product can increase the color scale of teeth by 5 to 8 VITA levels within a 14-day cycle, while keeping the incidence of sensitivity to cold and hot stimuli below 15%. The manufacturing process must pass the ISO 13485 medical device quality management system certification, and the cleanliness of the production environment should reach the 100,000-level standard.
Consumer experience data reveals key trends: Among nearly 120,000 reviews of sensitive teeth whitening patches on the Amazon platform, the repurchase rate of products with a comfort score of 4 stars or above reached 63%, far exceeding the industry average of 45%. The British Dental Journal reported that patches using sustained-release technology (such as Sensodyne True White) increased the proportion of users who used continuously for more than 30 minutes from 55% to 82%. It is worth noting that 40% of users aged 35 to 50 are willing to pay a premium of 20% to 30% for high-end products containing bioactive glass (such as NovaMin), which can form a 3-5 micron hydroxyapatite repair layer within 24 hours. The 2022 NHS Clinical report indicates that among users who used professional desensitizing and whitening patches in compliance with regulations, 87% did not observe a decrease in enamel microhardness after three weeks (test load: 200g, duration: 15 seconds).
Technological innovation continuously drives market transformation. Leading manufacturers are developing controlled-release films with a hydrogen peroxide release rate of ≤ 0.15mg/cm²/ hour, which have a 40% lower stimulation index compared to traditional products. In March 2024, a leading brand launched an intelligent patch that can monitor changes in the oral environment in real time and automatically adjust the release of active ingredients by integrating a pH sensor (with an accuracy of ± 0.2). Industry predictions suggest that by 2027, a new generation of products containing biological enzyme preparations (such as glucanase) will account for 30% of the market share, which can break down 95% of dental plaque pigments within 10 minutes. It is worth noting that according to the FDA’s adverse Event reporting system, the incidence of serious adverse reactions of compliant sensitive whitening patches was only 0.0037% from 2021 to 2023, which is much lower than the 0.018% of ordinary whitening products.
