Zoom Teeth Whitening is fairly painless but I have heard and read of many painful experiences which disheartens me and affects many dentists and offices that do uphold high quality and standards when conducting the procedure.
First of all, patients should always be screened for and treat any dental problems prior to whitening treatment to prevent painful incidences.
Furthermore, the procedure includes a step to protect gums from the active whitening solution which may burn.
Although there can be conditions when pain and sensitivity is experienced during and or after a whitening procedure (when whitening gel burns uncovered gums or seeps into the roots), the kit comes with a gel to treat it on the spot as well as post-whitening material and instructions .
One of the major factors in recommending Zoom in-office whitening to patients is that it is done with supervision and any pain and sensitivity can be treated immediately whereas, pain and sensitivity experienced with take-home kits can result in similar painful situations without instructions and material for immediate relief. With the proper precautions and management, the in-office Zoom whitening procedure should be fairly pain free and sick leave is not necessary.
