Smoking, consumption of tannin rich food (such as grapes, cranberries, green tea), and some cationic substances such as chlorhexidine may cause color change in teeth. These color changes usually occur in regions outside the effect of the toothbrush and paste.

In-office tooth whitening is the fastest and provides the highest whitening effect with minimum tooth sensitivity.

The bleaching process takes about 30 minutes. Some patients may experience dental complaints during this procedure. This condition is usually light and temporary.
