It’s no secret that a mouth full of whiter teeth provides benefits, the most obvious being – a brighter more attractive smile. Stains or overall discoloration tends to dull your smile, so regardless of how widely you smile or heartily you laugh, your expressiveness has missing something. Whiter teeth restore this missing dimension to your self-esteem.
What is teeth whitening?
Over time, your teeth can go from white to not-so-bright for a number of reasons, including bad habits, a medical condition, staining agents, dental plaque, or simply wear and tear.
A teeth whitening may bring back the brightness of your teeth so you can look and feel younger and lot more confident.
Teeth whitening can be achieved by either changing the intrinsic color or by removing and controlling the formation of extrinsic stains.
Hydrogen peroxide (H2O2) is the active ingredient most commonly used in whitening products and is delivered as either hydrogen peroxide or carbamide peroxide.
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”.
There are different products available on the market to remove stains. Nevertheless, a professional teeth whitening performed by a skilled dentist has a higher and more stable success, he can correctly diagnose the type, intensity and location of the tooth discoloration.
