What Is Teeth Whitening? A Complete Guide
“In smile design naturalness is essential; I aim for a balanced aesthetic that harmonises with your gums and suits your facial features.”
What Is Teeth Whitening?
Teeth whitening is an aesthetic procedure that lightens discolouration with peroxide-based gels, raising the shade without damaging the tooth surface.
Methods: In-Office and Home
In-office whitening uses high-concentration gel with light for a clear result in one session; home whitening uses custom trays with lower-concentration gel over days. The two can be combined.
How Does It Work?
Peroxide breaks down colour pigments in enamel and dentin to lighten the shade; a cleaning (scaling) beforehand is advised.
Causes of Discolouration
Coffee, tea, smoking, age-related yellowing and some medications cause discolouration; certain intrinsic stains resist whitening.
Who Is It For?
Ideal for adults with healthy teeth and gums; pregnant women and those with active decay/high sensitivity need treatment first.
Durability and Care
Results last months to years depending on diet and habits; reducing staining foods and periodic top-ups are advised.
Frequently Asked Questions
Is teeth whitening harmful?
Under dental supervision it is safe; it does not permanently damage enamel, though temporary sensitivity may occur.
In-office or home — which is better?
In-office is fast and controlled; home is more gradual. In most cases combined gives the best result.
How much lighter?
Usually a few shades; it depends on your starting colour and the method.
Does it cause sensitivity?
Temporary sensitivity may occur; desensitising gels and the right protocol reduce it.
Do crowns/fillings whiten?
No; porcelain/composite do not whiten. They can be renewed to match after whitening.
How long does it last?
Months to years; longer if coffee/tea/smoking are reduced and top-ups are done.
Are over-the-counter products effective?
Low-dose products have limited effect; dental supervision is both safer and more effective.
Why is it advantageous in Istanbul?
Experienced dentists, professional systems and affordable pricing — transparent, all-inclusive planning.
How do I know if whitening is right for me?
If there's no active decay, gum problem or excessive sensitivity, it suits most adults; we make the final decision at the examination. For structural discolouration, a veneer or crown may be needed instead of whitening.
How long does the whitening effect last?
The result is long-lasting, but a slight colour relapse may appear over time depending on lifestyle (tea, coffee, smoking). An annual touch-up session keeps the brightness.
Is home or in-office whitening better?
In-office gives a noticeable result in a single session, while a custom home tray progresses more gradually; the two can also be combined. We choose what suits you together.
