I've used Sensodyne for years for sensitivity issues. Last year, I tried a new version with whitening and after a couple of weeks my teeth started hurting all day long. It took me a couple of days until I made the connection. I stopped using that and went back to what is being sold (here in Mexico) as Sensodyne Original.
