Tooth Whitening

What is Teeth Whitening?

This type of discoloration is removed by tooth cleaning. In addition to these, aging, root canal treatment, antibiotics used in childhood (tetracycline) and various systemic disorders also cause discoloration on the tooth surface. The process of removing all these colors by applying various whitening materials to the tooth surfaces under the control of a physician is called bleaching.
The whitening rate is proportional to the person’s own tooth color. Teeth can be lightened by at least three to four tones with this procedure.

How is bleaching done?

Teeth whitening is a procedure to lighten the natural color of teeth or remove stains. The procedure usually involves the following steps:

  1. Examination and Assessment: The first step is for the dentist to examine the patient’s teeth and assess whether they are suitable for whitening. If the teeth have cavities, gum disease or other problems, whitening is not recommended before these problems are treated.
  2. Color Determination: The dentist uses a color scale to determine the patient’s tooth color. This helps to determine the initial tooth color and the result that can be achieved after whitening.
  3. Cleaning and Preparation: Before whitening, the teeth are cleaned and the gums are protected. The dentist may apply a special gel or layer to protect the gums and surrounding tissues.
  4. Application of Whitening Gel: In the home whitening method, the dentist provides the patient with a special dental tray and whitening gel. The patient places this gel in the tray and wears it for the specified period of time. In office-based whitening, the dentist applies the whitening gel in the clinic and accelerates the whitening process using a light or laser.
  5. Control and Evaluation of Results: With at-home whitening, the patient needs to use the whitening gel for a certain period of time. Once the treatment is complete, the dentist evaluates the results and recommends re-treatment if necessary. With office-based whitening, the results are usually seen in the same session.


Teeth whitening can be different for each patient and the results may vary from person to person. The dentist will perform an assessment to determine the most suitable whitening method for the patient and plan the treatment accordingly.

Home Application

Home teeth whitening is a procedure performed in the patient’s own home using special whitening products prescribed by the dentist. Home whitening usually involves the following steps:

  1. Examination and Preparation: First, the dentist will examine the patient’s teeth and assess their suitability for whitening. If there is gum disease or other problems, these will be treated. Then, preparatory procedures such as cleaning the teeth and taking impressions are carried out.
  2. Preparing the Dental Tray: The dentist makes a special dental tray to fit the patient’s mouth. These trays ensure that the whitening gel is evenly distributed over the teeth.
  3. Applying the Whitening Gel: The dentist gives the patient detailed instructions on how to use the whitening gel and dental tray. Patients put the gel in the dental tray and attach the trays to their teeth. Then, they keep the trays in their mouth for the specified time.
  4. Monitoring the Whitening Process: Patients usually wear their whitening trays for several hours or overnight. The dentist recommends that the patient undergo this procedure for a certain period of time and follows up as needed.
  5. Evaluation of Results: Once the whitening period is complete, patients are expected to observe the change in their teeth. When the treatment is over, the dentist evaluates the results and recommends additional treatments or check-ups if necessary.


Home teeth whitening can give effective results when practiced regularly and in accordance with the dentist’s instructions. However, this treatment may not be suitable for everyone and should be evaluated by the dentist.

Office Type Application

In-office teeth whitening is a professional procedure performed in a dentist’s clinic. It usually involves the following steps:

  1. Examination and Preparation: First, the dentist examines the patient’s teeth and assesses their suitability for whitening. If there is gum disease or other problems, these will be treated. Then, the teeth are cleaned and prepared for the whitening process.
  2. Color Determination: The dentist uses a special color scale to determine the patient’s tooth color. This helps to determine the initial tooth color and the result that can be achieved after whitening.
  3. Application of the Whitening Gel: The dentist applies a whitening gel and may use a special light or laser to enhance its effect. The gel is left on the teeth for a certain amount of time and then removed.
  4. Control and Evaluation of Results: Once the whitening process is complete, the patient is expected to observe the change in their teeth. Once the treatment is over, the dentist will evaluate the results and recommend additional treatments or check-ups as needed.


In-office teeth whitening provides faster and more effective results. It is safe because it is performed with professional equipment and by an experienced dentist. However, this procedure may not be suitable for everyone and should be evaluated by the dentist. Also, regular maintenance and dental hygiene are important to maintain the long-lasting effects of the treatment.

How Long Does the Treatment Last and When Do Teeth Return to Their Former State?

How long the teeth whitening treatment will last and when the teeth will be restored depends on several factors:

  1. Type of treatment: Home teeth whitening usually takes a few days to a few weeks. In-office teeth whitening, on the other hand, can usually be completed in a single visit.
  2. Patient’s Condition: Every patient’s teeth are different and whitening results vary from person to person. Some patients may take longer to achieve the desired results.
  3. Whitening Level: How much the teeth are whitened also affects the duration of the treatment. A short treatment time may be enough to remove light stains, while deeper stains or discolorations may take longer to correct.
  4. Patient Reaction: Patients may experience sensitivity or discomfort after whitening. In this case, desensitizing products or techniques recommended by the dentist can be used. This may affect the treatment time.
  5. Care and Protection: After teeth whitening, it is important that the patient adheres to dental hygiene and the care instructions given by the dentist. Proper care and regular check-ups can help maintain the whitening results for a long time.


After whitening, teeth usually appear whiter immediately. However, the permanence of whitening results may depend on personal care habits and diet. The color of the teeth may return if habits such as smoking, coffee or tea consumption continue or if dental hygiene is inadequate.

Is Whitening Painful or Harmful to Teeth?

Teeth whitening is usually painless, but some patients may experience slight sensitivity or discomfort during the treatment. This sensitivity is usually temporary after the treatment is over and subsides within a few days.

Teeth whitening usually does not harm dental health, but it can cause problems if it is not performed correctly or if it is performed on unsuitable candidates. For example, teeth whitening may not be recommended for people with tooth decay or gum disease. It may also not be recommended for pregnant or breastfeeding women.

There are concerns that the chemicals used during the whitening process can damage tooth enamel. However, professional teeth whitening is controlled by a dentist and does not damage the enamel. Especially in office-based whitening, the dentist takes special precautions to protect the enamel.

As a result, when done correctly, teeth whitening is generally safe and does not cause discomfort. However, if you have any concerns or are experiencing problems with your dental health, it is important to consult a dentist. The dentist can determine the most appropriate treatment options for you and guide the treatment process.
