Below, we introduce three mainstream cosmetic dentistry methods to help you achieve a perfect smile.
Option 1: Laser Teeth Whitening
Whitening Principle: Utilizes high-energy laser light to catalyze hydrogen peroxide, effectively removing surface stains through oxidation. Suitable For: Moderate tetracycline staining, drug-induced discoloration, or fluorosis, ideal for those seeking rapid whitening without periodontal disease or cavities.
Key reminder: The primary advantage of this method is its short treatment time and impressive whitening results. However, be sure to consult a professional for an assessment before treatment to avoid varying degrees of sensitivity afterward.
Option 2: Cold Light Teeth Whitening
Whitening Principle:Blue light with a wavelength between 480–520 nanometers is transmitted via optical fibers and directed through specially treated lenses onto a specialized whitening agent applied to the tooth surface. Within 30–40 minutes, the whitening agent penetrates through dentinal tubules, reacting with surface and deep-seated stains through oxidation-reduction processes to restore tooth whiteness.
Indications: Individuals with genetically yellow teeth, as well as those experiencing tooth discoloration or staining due to long-term smoking, coffee consumption, medication use, etc.
It is important to note that while this method delivers immediate whitening results with no side effects and causes no damage to teeth, individuals with severe tooth discoloration may require a second cold light treatment. Post-treatment sensitivity may occur to varying degrees.
Option 3: Cosmetic Porcelain Veneers
Whitening Principle: A thin layer is first removed from the tooth surface. Then, ultra-thin porcelain veneers (approximately 0.2mm thick) are bonded to the tooth surface to achieve whitening. This effectively smooths uneven tooth surfaces or repairs imperfections and also provides some teeth alignment correction.
Indications: Individuals with drug-induced tooth discoloration or those dissatisfied with laser or cold light whitening results.
