This system does cause teeth sensitivity, at least in my case. However, my hygienist suggested using ACT mouthwash after whitening and daily because it protects the nerve endings that cause the sensitivity.
I have been doing that and it definitely has made a difference for me. They are still sensitive, but nothing like what I have experienced in the past with other whitening attempts.
