Tea, coffee, tobacco products, acidic beverages consumed in daily life, the use of antibiotics at young ages and even aging can cause discoloration of the teeth. Bleaching is applied to reduce the yellow or brown tones that occur on the teeth. 

Bleaching is a process performed to clean the colored organic or inorganic substances in the enamel and to restore the natural whiteness of the teeth. The patients who will undergo the bleaching procedure are first examined and their suitability for bleaching is checked by the dentist. Firstly the tooth surface is cleaned. Then the tooth tone is determined. During the application, a gingival protective gel is applied to prevent damage to the gingiva and the patient wears glasses to protect their eyes. A concentrated whitening gel containing hydrogen peroxide is applied to the teeth to remove stains, and then a laser is used to heat and activate the applied gel, which quickly whitens your teeth. Bleaching process takes an average of 30-60 minutes. 

Bleaching  is an easy and painless procedure and does not require anesthesia. Depending on the tooth structure, sensitivity may be felt on the first day and the patient can use pain killers if he/she prefers. Patients who have bleaching should avoid tea, coffee, cigarettes, red wine and food dyed foods/drinks for the first few days. 

Depending on the stain status on the teeth, the desired whiteness can be achieved with a single session application, or it may be necessary to repeat the sessions several times. The frequency of recurrence may vary depending on factors such as how much importance the patient attaches to dental hygiene and care, and whether he or she uses tobacco products. 

Bleaching does not harm your teeth, gums and, if any, crowns or veneers in your mouth. However, it is not recommended for those who have a lot of corrosion on their teeth, those who have a disease related to tooth enamel, those who are allergic to hydrogen peroxide or carbamide peroxide, and those who have advanced gum recession.
