Teeth whitening can be a highly effective way of lightening the natural colour of your teeth without removing any of the tooth surface. It cannot make a complete colour change; but it will lighten the existing shade.
There are a number of reasons why you might get your teeth whitened. Everyone is different; and just as our hair and skin colour vary, so do our teeth. Very few people have brilliant-white teeth, and our teeth can also become more discoloured as we get older.
Your teeth can also be stained on the surface through a lot of colour containing food and drinks such as tea, coffee, red wine and blackcurrant. Smoking can also stain teeth.
Calculus or tartar can also affect the colour of the teeth. Some people may have staining under the surface , which can be caused by certain antibiotics or tiny cracks in the teeth which take up stains. At Hai Dent we can provide in office ZOOM whitening and home whitening.

Bleaching In dentistry is treatment modality involving Oxidative Process that alters Light absorbing and/or light reflecting nature of material structure thereby inceasing the perception of whiteness in terms of Hue.
Hydrogen peroxide (H2O2) is the active ingredient most commonly used in whitening products and is delivered as either hydrogen peroxide or carbamide peroxide. Hydrogen peroxide is analogous to carbamide peroxide as it is released when the stable complex is in contact with water. When it diffuses into the tooth, hydrogen peroxide acts as an oxidising agent that breaks down to produce unstable free radicals. In the spaces between the inorganic salts in tooth enamel, these unstable free radicals attach to organic pigment molecules resulting in small, less heavily pigmented components. Reflecting less light, these smaller molecules create a "whitening effect".
