In daily life, some individuals have severely yellowed teeth, which diminishes their confidence. To avoid embarrassment, they may avoid social interactions. Consequently, they resort to whitening strips to mask their imperfections, unaware that this merely provides a superficial solution with very short-lived effects. Therefore, caution is advised when using whitening strips for teeth whitening.
According to experts, the mechanism of whitening strips is straightforward: a thin film encapsulates whitening chemicals that gradually permeate the teeth, achieving a whitening effect over time.
Teeth yellowing or darkening stems from both extrinsic and intrinsic factors. Extrinsic factors involve daily habits like drinking tea, coffee, or smoking, which deposit pigments on teeth over time. Intrinsic factors occur during tooth development when dentin undergoes discoloration due to genetic predisposition, medication, water quality, or other internal/external influences.Clearly, whether caused by extrinsic or intrinsic factors, whitening strips cannot fundamentally eliminate these stains.
It is reported that overseas, whitening strips are generally used as temporary cosmetic treatments for teeth, much like lipstick, typically applied before social events. The current surge in teeth whitening trends within China is concerning. We understand that a set of bright white teeth does not necessarily equate to healthy teeth.The primary ingredient in whitening strips is hydrogen peroxide. Prolonged application may irritate dental nerves, causing sensitivity, cold sensitivity, soreness, or even structural damage to teeth. Therefore, whitening strips should not be used frequently or excessively. Users with poorly developed enamel or significant tooth wear may experience more pronounced sensitivity.
