Common reasons include: Faulty PCB design or low-grade electronic components; Software glitches causing misinterpretation of user input or position; Environmental factors like moisture ingress or temperature fluctuations. A failed sensor may not detect excessive brushing pressure or incorrect positioning, raising…
In the rapidly evolving market of oral care devices, particularly electric toothbrushes and whitening applicators, cases of brush discoloration combined with hydrogen peroxide burns are becoming a concern for both users and manufacturers. While these issues may appear superficial at first glance, ignoring them could expose end-users to safety risks and damage the brand's reputation. But is this truly something manufacturers can afford to overlook? What Causes Brush Discoloration? Brush discoloration often results from repeated exposure to whitening gels containing hydrogen peroxide. Factors contributing to this include: High concentrations of peroxide that degrade bristle materials; Heat generated during device operation, accelerating chemical breakdown; Poor-quality bristle polymers that react easily with oxidizing agents. Over time, this leads to noticeable yellowing, fading, or spotting on the brush head—clear signs that chemical damage is taking place. How Hydrogen Peroxide Burns Occur In parallel, hydrogen peroxide burns can affect the user’s soft tissues—particularly gums and lips—when whitening agents leak or are improperly applied. Such burns typically arise from: Overfilled whitening trays or misaligned applicators; Gel seepage caused by poorly fitting devices; Excessive peroxide concentration without proper neutralizing agents. These burns manifest as irritation, whitening of the mucosa, or even pain—and in severe cases, tissue…
In the field of sonic toothbrush manufacturing, button malfunction and uneven bristles might seem like unrelated issues at first glance. However, increasing customer feedback indicates that these two flaws can interact, resulting in product failure, reduced brushing efficiency, and poor user experience. Is this truly an overlooked disaster in oral care design—or a preventable manufacturing defect? How Button Malfunction Triggers Bristle Deformation A button malfunction, such as a stuck or delayed power button, can unintentionally cause the motor to operate erratically. This leads to: Over-vibration during rest periods; Unplanned sudden start/stop cycles; Extended high-speed running without load. Such irregular operation strains the brush head, causing uneven bristles over time as the fibers wear at different rates due to inconsistent pressure and motion. The Role of Uneven Bristles in Brushing Inefficiency Uneven bristles are not merely a cosmetic problem—they seriously undermine brushing quality. They cause: Incomplete plaque removal in certain areas; Over-scrubbing of gum tissue, raising the risk of irritation or recession; Imbalanced motor load, increasing the chance of future button malfunction due to feedback strain on internal electronics. In B2B production, such flaws can damage the brand’s reputation and result in costly product returns. Company web: https://www.powsmart.com/product/electric-toothbrush/ Root Causes Behind Button…
