Yes, you can

Peter Boulden, DMD answers: Can I buy the toothpaste that will reduce sensitivity prior to Zoom treatment over the counter?

I am extremely nervous now about the Zoom procedure. I never even considered pain involved until I read all these reviews. If there is a toothpaste that will help with the sensitivity prior to getting in the dentist chair, then I would like to purchase it. Thank you for your help!

The active ingredient you're looking for is called Potassium nitrate (and fluoride).  Potassium nitrate works by actually clogging the "pores" (technically called 'tubules') in your tooth, if you will.  This can aid in the sensitivity reduction experienced in whitening.   It takes about 2 weeks to fully 'clog' the pores in the tooth though.
