Mostly, a mouthpiece tray which does not fit properly is responsible for the irritation of the soft tissues. But both these conditions and discomfort do not persist for long and last only for a temporary period of one to three days of the completion of the treatment. In case of acute sensitivity one can follow a few simple measures to reduce or get rid of the teeth whitening risks. Firstly, the mouth tray can be used for a shorter period of time for example, instead of two 60 minute sessions it can be worn for two 30 minutes sessions. Again, the process can be stopped for a few days to allow the teeth to get adjusted to the teeth whitening treatment. Moreover, the dentist or the pharmacist can be asked to prescribe a product containing high fluoride to restore the mineral content of the teeth.
This product should be applied to the tray and to be worn for four minutes before starting the whitening process. Lastly, brushing the teeth with toothpaste meant for sensitive teeth containing potassium nitrate helps soothe the nerve ends of the teeth. Such steps might alleviate the teeth whitening risks and irritations to some degree.
