Hello sir...     Teeth whitening can be done at home which is called home teeth whitening technique.. This also can be done under the guidance of dentist.... In office teeth whitening is more effective than home bleach technique...      Sensitivity of teeth is due to so many cause like cavitation on your teeth, cervical abrasion,  erosion due to faulty tooth brushing technique... Or enamel erosion due to chemical drinks...     Yes,  listerine  can use as a regular mouth wash twice daily after food...

Home teeth whitening increase your sensetivity. Stop using Listerin it won't help in sensetivity,  use sensodyne rapid relief for one month & sendyne repair & protect for 3 months.  If not got relief,  go to dentist for proper cheakup.

1st book your appointment with your dentist and find out the root cause for your sensitivity. Stop using listerine it has a side effect of sensitivity in few cases. Cant jump into conclusion without seeing your teeth

There comes a bleaching kit at home use but since u already have sensitivity it can increase your sensitivity.u can use listerine for a month and then stop otherwise it can cause staining of teeth.
