Okay here is a question.... I have a gray undertone to my teeth. I have tried numerous?

You can try with 30 second smile toothbrush. It worked for me. Message me if you are interested.

I am in the dental field and have actually performed the chair side bleaching procedure many times for patients and also made trays for them to take home as you have done. Unfortunately I have to explain to them that gray stains and gray overtones just don't bleach as well. For some reason these stains just don't bleach as well as yellow stains.

We have had some gray-stained patients that have had some luck with the chair side bleaching method where the teeth are bleached right in the office. If you haven't tried this method you might want to look into it...and also continue to bleach at home for a week or so after you have the procedure in the office. This might make them a little whiter.

I actually wrote a hub on the three bleaching methods if you would like to take a look..hubpages.com/hub/some-interesting-....

Sorry my news is not so good for you...but most of the time people's teeth are not as stained as they think and actually the gray stains are much less noticeable that the yellow!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
