What Is Teeth Whitening? How It Is Done, Methods, Durability and Costs

Teeth whitening is an aesthetic dentistry procedure aimed at making teeth that have yellowed or become stained over time a brighter and more radiant shade. Nowadays, this procedure can be applied both in-office (in a clinical setting) and at home, and aims to lighten the tooth shade without damaging the tooth enamel.

What Is Teeth Whitening?

Teeth whitening is the process of removing discolouration from the tooth surface using special whitening gels and lightening the tooth colour by several shades. This procedure can be effective in removing stains caused by external factors such as tea, coffee and smoking, and in cases of age-related colour changes.

When applied professionally, it ensures controlled, safe and aesthetic results. However, which method is suitable should be determined based on the person's tooth structure and current level of discolouration.

How Is Teeth Whitening Done?

Teeth whitening is planned based on the current shade of the teeth and the patient's needs. Before application, tartar cleaning is performed and the gums are checked. After a healthy oral structure is ensured, the whitening procedure is performed.

Teeth whitening is generally applied using two different methods:

Clinical (In-Office) Whitening

This method is applied by the dentist in the clinical setting. The gums are isolated with a protective barrier and a special whitening gel is applied to the tooth surface. The gel is activated at regular intervals to lighten the tooth shade by several tones. The procedure is usually completed in a single appointment and results are seen quickly.

At-Home Whitening

In this method, a custom-fit tray is prepared by taking a measurement specific to the patient. The whitening gel provided by the dentist is placed inside these trays and applied at home for specific periods. The process can take several days and the colour lightening occurs gradually.

Which method will be preferred is determined based on the level of tooth discolouration and the patient's expectations. When performed under professional control, the procedure produces safe and effective results.

What Is Laser Teeth Whitening?

Laser teeth whitening is a professional tooth whitening method applied in a clinical setting using light or laser technology combined with a special whitening gel. In this procedure, the whitening gel applied to the tooth surface is activated with laser or a special light source, aiming for faster and more effective results.

Before the procedure, the gums are protected with an isolating material. The whitening gel is then applied to the tooth surface and activated with laser light at specific intervals. The treatment is usually completed in a single session and can produce a visible lightening of tooth shade.

Laser teeth whitening is particularly preferred by patients seeking quick results and those with heavy discolouration. However, suitability must always be assessed following a dental examination.

What is Home-Based Whitening?

Home-based whitening is a tooth whitening method carried out under the supervision of a dentist, performed by the patient in their home environment. In this treatment, custom-made transparent trays are prepared based on impressions taken specifically for the patient, and the whitening gel recommended by the dentist is placed in these trays for use over specific periods.

The whitening gel gradually lightens the discolouration on the tooth surface. The treatment usually lasts from several days to a few weeks, and results are seen gradually.

Home-based whitening is a more controlled and gradual process. When planned by a dentist, safe and effective results can be achieved. However, it should always be carried out based on professional advice rather than using randomly purchased products.

Which Method is More Effective?

The effectiveness of tooth whitening varies depending on the current level of discolouration of the teeth and the patient's expectations. Professional whitening applied in a clinical setting (office-type using laser/light) generally produces more noticeable results more quickly and in a shorter timeframe. Home-based whitening provides a more controlled and gradual lightening.

In patients with heavy discolouration who want quick results, professional whitening may be more effective. For lighter colour changes or in people with sensitive teeth tendencies, the home-based method may be preferred. The most suitable method should be determined following an examination.

How Many Shades Does Teeth Whitening Lighten?

Tooth whitening usually produces a lightening of several shades. The results obtained depend on the initial tooth shade, the structure of the enamel, and the method used.

In some patients a noticeable brightening is seen, whilst in other cases a more natural and subtle shade lightening is achieved. The aim is not an artificial whiteness, but a tooth shade that is harmonious with the face and appears healthy.

Is Teeth Whitening Permanent?

Teeth whitening is not a permanent procedure but provides long-lasting results. The duration of the effect depends on a person's dietary habits, smoking use, and oral hygiene.

Staining factors such as tea, coffee, and smoking can cause the whiteness to fade over time. With regular maintenance and, if necessary, touch-up treatments at certain intervals, the whiteness can be preserved.

Is Teeth Whitening Harmful?

Teeth whitening is a safe aesthetic procedure when applied under dental supervision and with appropriate products. Professional whitening gels are designed to lighten shade without damaging tooth enamel.

However, uncontrolled use of products with unknown composition can damage tooth enamel and gums. Therefore, whitening should always be carried out under dental recommendation and supervision.

Does Teeth Whitening Cause Sensitivity?

Following whitening, some patients may experience temporary tooth sensitivity. This is usually short-lived and reduces naturally within a few days.

The intensity of sensitivity may vary depending on tooth structure, the method used, and any existing sensitivity. This condition can be managed through desensitising products recommended by the dentist and correct application protocol.

Teeth Whitening: Who is it Suitable For?

Teeth whitening is suitable for many adults who are dissatisfied with their tooth shade and wish for a brighter smile. Particularly effective results can be achieved in cases of yellowing and staining caused by external factors.

Can be preferred in the following situations:

• Those with staining from tea, coffee, or smoking

• Those experiencing age-related tooth yellowing

• Those wishing for an aesthetically brighter smile

• Individuals with good overall oral health

If cavities, gum disease, or tartar are present before the procedure, these must be treated first.

Teeth Whitening: Who is it Not Suitable For?

As with any aesthetic procedure, teeth whitening may not be recommended in certain situations.

Careful assessment is required in the following cases:

• Those with active gum disease

• Patients with untreated cavities

• Those with severe tooth sensitivity

• Pregnant and breastfeeding individuals

• Patients with numerous restorations or fillings in the anterior region

In these cases, necessary treatments should be planned first, and then suitability should be reassessed. The most appropriate decision is made following a dental examination.
