Tooth discoloration can occur due to developmental dental diseases, the use of medications that cause staining during childhood, plaque buildup, external factors such as frequent consumption of tea, coffee, or smoking, and natural aging. Superficial stains on discolored teeth can be removed through brushing and dental cleaning, while deeper stains require whitening treatments. Whitening procedures can be performed in two ways: in-office whitening and at-home whitening.

It is the fastest and most effective whitening method. Performed in the clinic by a dentist, a whitening agent is applied directly to the patient’s teeth. Using adjustable light intensity and LED technology, effective results are achieved in a short time.
The procedure is straightforward: initially, the lips and other soft tissues are protected with a brief isolation. After clinical preparations, a whitening gel is applied to the teeth, and light is used to activate the gel. Finally, a desensitizing gel is applied for about five minutes to complete the whitening process. Depending on the preferences of the patient and dentist, the treatment can be repeated in one or two sessions. The major advantage of this system is that the patient can see noticeable results within minutes, without leaving the clinic.
Impressions are taken from the patient to create transparent mouth trays. Whitening gels provided by the dentist are placed into these trays, which the patient wears for 3–4 hours daily. The duration of the treatment varies depending on the intensity of the tooth discoloration, the tooth color, the desired shade of whitening, and any sensitivity that may develop.
