What Causes Tooth Discolouration?
Tooth colour can change with age. Tea, coffee, tobacco products and some foods may contribute to surface staining. Other colour changes may be related to the internal structure of the tooth, medications, trauma or previous dental treatment.
Not every type of discolouration responds to whitening in the same way, which is why assessment before treatment is important.
What Is Teeth Whitening?
Teeth whitening is an aesthetic dental procedure that uses whitening agents in a controlled manner to lighten tooth colour.
The degree of shade change that can be achieved varies between individuals and depends on the starting shade of the teeth.
In-Office Teeth Whitening
In-office whitening is carried out in the clinic by applying whitening products to the teeth while protecting the gum tissues.
The number and duration of appointments may vary according to the system used and the condition of the teeth.
Take-Home Teeth Whitening
For take-home whitening, custom trays may be prepared and a dentist-provided whitening product is used for the prescribed duration and frequency.
The amount of product and duration of use should be determined individually. Unsupervised use of whitening products without dental advice is not recommended.
After Teeth Whitening
Temporary sensitivity may occur after whitening. Reducing habits that contribute to staining and maintaining regular oral care may help preserve the result.
How long the whitening effect lasts may vary according to dietary and oral-care habits.
