A smile with pearly white teeth always leaves a positive impression. That's why teeth whitening has become so popular and important for modern people. But is cold light whitening suitable for everyone? We're curious too! Let's explore some basics about cold light whitening.
How Cold Light Whitening Works
Cold light whitening uses a neutral whitening agent. Under the light emitted by the whitening lamp, the agent gradually penetrates the teeth,removing stains to achieve whitening effects. The chemical reaction that whitens teeth occurs in about 45 minutes. The hydrogen peroxide solution used in the treatment has been safely applied to teeth for over a century. Most ultraviolet and infrared rays are filtered out, so the light shines coolly on the teeth, meaning the process is very safe.
How Safe is Cold Light Teeth Whitening?
Cold light whitening has been safely used for decades in teeth bleaching. The process avoids contact with gums and causes no damage to tooth structure or enamel. Its single-use, non-irritating, side-effect-free whitening results last over two years. It is therefore widely recognized as the most effective and safest teeth bleaching technology available today.
Who should not undergo cold light whitening?
1. Patients with tetracycline-stained teeth cannot benefit from cold light whitening. For such cases, only covering methods like porcelain veneers can achieve whitening.
2. Individuals with cavities or dead pulp teeth are unsuitable for cold light whitening.
3. Cold light whitening is ineffective for individuals with enamel hypoplasia. Therefore, it is crucial to consult a dentist beforehand to confirm whether your teeth can be improved through this procedure.
4. Yellow substances in tobacco adhere to teeth, gradually depositing pigments that penetrate deep into the enamel, causing the tooth surface to yellow and darken.While long-term smokers may see temporary color improvement after whitening, the habit is often difficult to quit. Subsequent smoking will quickly reintroduce stains, rendering the procedure largely ineffective.
