Does Opalescence whitening cause tooth sensitivity?
The higher concentration formulas can most definitely cause tooth sensitivity. If you experience sensitivity, you should try a less concentrated formula (i.e. 10%). The other option is to use a desensitizing gel immediately after whitening your teeth (i.e. Relief ACP Oral Care Gel, UltraEZ Desensitizing Gel). A study done by Dr. Wm Browning of Medical College of GA tested the sensitivity factor of Opalescence PF 10%, NiteWhite Excel 2Z 10% and Rembrandt XtraComfort 10%. The study found that all exhibited some degree of sensitivity but Opalescence users had less sensitivity and for a significantly shorter period of time.
