Until recently I thought there was just the Crest Whitening Strips available to consumers.

So I was going to try them then I read that many people were getting sore gums from using them.

Does anyone have a teeth whitening product that they would recommend?

Thanks.

I think colgate simply white works great.

I tried crest nigh effects and it was a pain.

Good luck

I used Crest Whitestrips, and hated them. I used Colgate Simply White, and decided it was more for short term whitening. It works really quick, but it doesn't last long. Right now, I'm using Crest Night Effects. Last night was my first night. It feels kind of weird, because it is such a thick layer, but the results after just 1 night are awesome.
