For Whiter and Brighter Smiles: What Is Teeth Whitening?
Teeth whitening (bleaching) is the process of lightening teeth that have become yellowed or stained over time using professional whitening techniques. The goal is to achieve a healthy and aesthetic appearance without damaging the natural tooth structure. As one of the most popular cosmetic dental procedures today, teeth whitening is widely preferred for its quick and safe results.
Factors such as coffee, tea, smoking, and consumption of colored foods and beverages can cause discoloration over time. Teeth whitening removes these stains, restoring the teeth to their natural, brighter shade.
Types of Teeth Whitening
Teeth whitening can be performed either in a dental clinic or at home:
In-Office Whitening (Professional Whitening)
Performed by a dentist using a special gel and light source. Results are achieved within a single session, with teeth lightened by 2–3 shades. It offers fast and effective results.
At-Home Whitening
Personalized trays and whitening gels provided by the dentist are used at home. With 4–6 hours of daily use, noticeable results can be achieved within about a week.
Combined Whitening
A combination of in-office and at-home techniques for patients seeking long-lasting results.

The whitening effect is long-lasting but may fade over time depending on lifestyle. A touch-up every 6–12 months can maintain the brightness.
