Teeth whitening is now a lucrative business, as many people suffer from diminished confidence due to dental imperfections. That's why we often choose cosmetic procedures to brighten our smiles. But do you know who is suitable for cold light teeth whitening?
Experts indicate that if your teeth exhibit the following conditions, cold light whitening may be an option:
1. Fluorosis: Primarily caused by excessive fluoride in drinking water.Mild cases show cloudy, opaque enamel with a chalky white appearance; moderate cases exhibit yellow or brownish-yellow irregular patches; severe cases involve not only discoloration but also enamel defects on the tooth surface.During tooth development, particularly in children under 8 or pregnant women, taking tetracycline antibiotics (e.g., tetracycline, oxytetracycline, doxycycline) can cause tooth discoloration known as tetracycline staining. This occurs because tetracyclines bind with calcium ions in tooth tissue to form stable tetracycline calcium salts. Discoloration typically worsens with age and stabilizes around age 18.
3. Pigment Deposition: Over time, certain pigmented foods and beverages—including tea, coffee, soy sauce, and tobacco—can accumulate on teeth due to inadequate oral hygiene. These pigments may penetrate deep into tooth structure, causing yellowing or darkening of the enamel surface. Much like stained white clothing that cannot be restored to its original whiteness through washing, conventional teeth cleaning often fails to reverse this discoloration.
4. Enamel Hypoplasia: During tooth development, the surface enamel may form abnormally due to insufficient calcium, phosphorus, vitamins A and D, or exposure to harmful factors. Mild cases present as opaque chalky-white, porous, and rough enamel surfaces that may stain yellowish-brown from food.In severe cases, substantial enamel defects may appear as pitted or band-like lesions, or even complete enamel loss.
5. Dental Caries: Commonly known as cavities or tooth decay, this condition arises when bacteria ferment sugars to produce acids that erode tooth structure. Over time, this softens the tooth, disintegrates dental tissue, and forms black cavities.
6. Non-vital teeth: Often caused by deep caries bacterial infection or direct traumatic impact, resulting in accidental tooth fracture, pulp necrosis, and subsequent discoloration.
From the above, we understand that teeth whitening requires proper methods. Not everyone is suitable for cold light teeth whitening procedures. Individuals who qualify for this method can undergo cosmetic dental enhancement through it.
