Tooth Whitening

(Teeth Whitening)

Tooth whitening is a procedure that aims to make discolored teeth appear whiter. Discoloration can occur due to two main causes: extrinsic factors, such as stains from food, beverages, and smoking, and intrinsic factors, such as the accumulation of pigmented substances during tooth development or in cases of tooth decay. Therefore, there are several methods of tooth whitening depending on the underlying cause of discoloration.


  1. In-office Power Bleaching: This is a tooth whitening procedure performed by a dentist in a clinic using highly concentrated bleaching agents. Various techniques and tools may be used.
  2. At-home Bleaching: This involves using a custom-made tray provided by a dentist to perform tooth whitening at home. The dentist will take impressions of the mouth to create a bleaching tray, and the patient will be instructed to apply the bleaching gel into the tray and wear it during sleep.
  3. In-office Assisted Bleaching: This is a combination of both in-office and at-home bleaching. It is typically recommended when the initial tooth color is highly pigmented. The procedure starts in the dental clinic and continues at home.
  4. Over-the-counter Bleaching: This refers to tooth whitening products available for self-use without the need for professional supervision. These products can be purchased from general stores, pharmacies, and beauty product retailers.
  5. Internal Bleaching: This is a tooth whitening procedure used for individual discolored teeth, usually caused by tooth decay. It focuses on whitening a specific tooth and not the entire mouth.

  1. Avoid consuming dark-colored or highly pigmented food and beverages. This includes refraining from smoking for at least one week. It is recommended to use straws when drinking dark-colored beverages or opt for lighter alternatives.


  2. Practice good oral hygiene by consistently brushing your teeth using the correct technique, especially after meals and before bedtime.


  3. Regularly consult with a dentist if your teeth start to show signs of discoloration. Generally, tooth sensitivity from whitening treatments subsides within 1-2 days, but in some cases, it may last up to one month. In such cases, the dentist may recommend using a toothpaste containing potassium nitrate to reduce sensitivity.
