When users complain of whitening unevenness, many manufacturers focus solely on bleaching formulations and overlook how improper frequency settings can lead to motor overheating and undermine product durability. In fact, incorrect vibration frequencies not only reduce activation efficiency but also accelerate enamel fatigue in localized areas, resulting in uneven whitening and increased wear. The Link Between Frequency Settings and Whitening Uniformity First, the frequency of cold-light or sonic activation directly dictates the speed and depth of free-radical generation: Low-Frequency Modes (<20 kHz) lack sufficient energy to break down deeper stains, causing superficial whitening. High-Frequency Modes (>30 kHz) improve penetration but concentrate energy and risk over-oxidation “hot spots.” Frequency Fluctuations: Without proper firmware compensation for voltage drops, load-dependent frequency jumps amplify whitening unevenness. Achieving precise and stable frequency output is therefore fundamental to consistent whitening. How Improper Frequencies Stress Enamel Next, mismatched frequencies impose cyclic stresses on the enamel surface: Micro-fatigue: High-frequency oscillations propagate micro-cracks, diminishing enamel hardness. Chemical-Mechanical Synergy: Vibration accelerates peroxide erosion, increasing surface porosity where stains can re-adhere. Localized Overheating: Excessive frequency settings can lead to motor overheating, transferring heat to tooth surfaces and intensifying chemical attack. Altogether, improper frequency settings are a key driver of both enamel…
