TOOTH WHITENING
Sensitivity and soreness following whitening is very common. Your teeth may be especially sensitive to cold air and drinks and if any of the whitening agent gets on your gums, it may cause them to be tender. Sensitivity and soreness will gradually subside after a couple of days. If you are more prone to sensitivity, you may chose to use anti-sensitivity toothpaste before, during, and after whitening.
Try to avoid any darkly or reddish colored foods and beverages (red sauces, coffee, red wine, tea) and smoking for a few hours following whitening. This is when your teeth are most susceptible to absorbing new stain. To maintain your shade for as long as possible, avoid colorants (dark food and drinks, tobacco), use a whitening toothpaste, and have regular cleanings. You may need to use home whitening trays once or twice a month to maintain your shade.
