Teeth whitening is one of the most effective aesthetic procedures that can create a noticeable difference in a person’s appearance. White teeth, which stand out when speaking and smiling, contribute to a more attractive, elegant, and healthy look. Over time, teeth may become yellowed or stained due to various reasons, but modern teeth whitening methods offer an easy and comfortable way to restore their natural whiteness.
What is Teeth Whitening?
Teeth can change color due to aging, genetic factors, dietary habits, dental treatments, and insufficient oral care. White and healthy teeth not only enhance a person's confidence but also provide an aesthetically pleasing appearance. Teeth whitening (bleaching) is a painless and quick treatment method designed to lighten the natural shade of teeth by several tones.
Before and After Teeth Whitening
Before | After |
---|---|
Yellowed, stained, and dull teeth | Brighter and whiter teeth appearance |
Discoloration due to coffee, tea, and smoking | Teeth free from stains and yellowing |
Uneven tooth coloration | More uniform and balanced tooth color |

What Are the Teeth Whitening Methods?
Teeth whitening is an aesthetic procedure performed by a dentist. The most suitable method is determined based on the individual's tooth structure and degree of discoloration before starting treatment. The most commonly used teeth whitening methods include:
-
Home Teeth Whitening
In the home teeth whitening method, the treatment process takes place at home. The dentist prepares custom whitening trays based on the patient's dental measurements. These trays contain a special whitening gel that directly interacts with the teeth to produce results. The patient can wear the trays for at least 4-6 hours during the day or overnight. The desired whiteness is typically achieved within an average of two weeks.
-
In-Office Teeth Whitening (Laser Teeth Whitening)
Also known as Power Bleaching, this method is performed in a clinic using laser technology. The dentist applies a special whitening gel to the teeth and activates it with laser light. This procedure, which takes approximately one hour, provides fast and effective results. Depending on the severity of tooth discoloration, one or multiple sessions may be required.
-
Combination Teeth Whitening
This method combines both in-office and home whitening techniques. First, laser whitening is performed in the clinic, and then whitening trays are provided for home use. It is ideal for those seeking longer-lasting and more permanent whitening results.
-
Single-Tooth Whitening
Single-tooth whitening is specifically designed for teeth that have darkened following a root canal treatment. During the procedure, the old filling is removed, and a whitening gel is applied inside the tooth. A temporary filling is used throughout the treatment process, and once the desired whiteness is achieved, the procedure is completed with a permanent filling.
