Helps A Bit, At Least
My teeth are a lot older than those of the models shown here and have been through plenty of coffee and cigarettes. I tried these on the two-week regimen and am reporting some success. The strips were easy to apply and held fast to my teeth as long as I wiped them dry with a paper towel just beforehand. It is recommended that you leave them on for a half hour or longer and I thought that may confine me but I was able to drink during the waiting time which went by pretty quickly each evening. No problem talking at all. After completing the procedure I would say that I did notice some lightening in my smile. It probably could help others as well.
