A big key is to not put the strips on after you’ve brushed your teeth. Your teeth are always more sensitive after you brush, and the whitening causes further sensitivity. If you are feeling pain, you should space them out more. I talked to my dentist prior to using the whitening strips, and he gave me the above tips!

Also, the sensodyne doesn’t work right away. Its active ingredient is potassium nitrate, which penetrates into your teeth over a period of about two weeks to block the sensitive nerve endings. My dentist told me to not expect overnight response with the sensodyne.

I always brush my teeth with sensodyne about a week (sometimes more) before I use the whitening stuff – that helps and I try to keep my face away from the cold! 🙂

I had my teeth whitened awhile ago and it went away after about 5 days. So, once you’re done whitening, give it a week for the sensitivity to subside.

I am doing the same; my teeth get sensitive if I do it back to back so I give it  a rest; it also hurts if I just brush my teet I didnt beleive it and lo and behold they hurt


so I’m doing it once a day rather than twice a day my teeth look whiter now

it has hydrogen peroxide they same component they use to bleach the hair

I also saw sodium hydroxide; when I used to do my chemistry class we were always warned not to get in contact with it because it burns; probably why it hurts probably a low strength but can still hurt

It is best to consult your dentist before attempting teeth whitening procedures. In case, you face hypersensitivity during and after the process, a dental care professional will best evaluate the problem and come up with an effective solution. There are several factors that can affect tooth sensitivity post whitening and not all of them originate from the whitening procedures and consulting a professional will help identify it appropriately.

DaisyBride:  here’s an explaining why teeth can become sensitive right after whitening


It’s also good to note not to brush right after whitening as the hydrogen peroxide is an acid (weakens the enamel) and brushing right away can cause more damage. The hydrogen peroxide also messes with your gums which is why a retainer/tray made at the dentist is best for eliminating that  

I personally would recommend not doing whitening long term but maybe a few weeks prior to the event. That said don’t over do it- I spent the first day of Dental school barely smiling because my teeth were so sensitive. Lesson learned!
