Does tooth whitening cause tooth sensitivity?

In some cases patients mention sensitivity while they are doing the treatment. This is due to the
fact that the tooth is slightly more porous during treatment and is reversible after it.
For this reason if you already suffer from sensitivity you’re not a good candidate for dental
bleaching because sensitivity will certainly rise and can be an issue.
From my experience sensitivity is less when you use the night product, for this reason it is my
favorite one.
