The causes of discolouration in teeth may be ageing, wearing due to acid or trauma, discolouration due to drugs, foods, incorrect tooth brushing habits, bad habits such as smoking, diseases and substances such as fluorine. Many of these can be removed by bleaching(whitening). The cause of discolouration plays an important role in the effectiveness of the bleaching process.

Home Type Whitening
Special moulds are prepared by measuring the teeth of the patient. The patient puts the bleaching agents into these moulds and places them on his teeth. During the periodic checks, the physician decides how long this procedure will be used during the day and how long it will continue. Approximately 2 to 8 hours per day is enough. The application continues for a week or two.
Office Type Whitening
This is a faster and more effective whitening type. It is a professional whitening method performed by the dentist in the clinic. Dentist covers the gums with preservatives. Subsequently, he applies the materials used to bleach the teeth. By using rays, these whitening drugs are provided to the function. The session may take from 45 minutes to 1 hour. Several supportive sessions may be performed until the desired whiteness is achieved.
Bleaching can be applied at almost any age. It is harmless when applied correctly. Depending on the person's smoking, feeding or brushing habits, further reinforcement may be required in the future. Sensitization may occur during the treatment process. Fluorine applications may eliminate these sensitivities. The patient can achieve up to 10 tons of bleaching depending on the case. During treatment, the patient should avoid factors that may cause discolouration.
