Do You Use Whitening Toothpaste?

[JaniceSW]

Do you use whitening toothpaste consistently and do you see any results?  Do you use the same brand?  What brand have you found most effective?  I heard that the method that dentists use with the light is quite painful. I can't recall the name of the procedure.  Anybody heard about this problem?  I have a lot of dental work, including implants, but I was wondering what people are finding.
