Colgate is always coming out with something new. I was sent over Colgate Optic White toothbrush that has a built-in whitening pen.
This toothbrush is something that I have never seen before and I am happy that Colgate has come out with something like this. This is the best two side toothbrush on one side you have your brush and on the other you have the pen with gel to take all the stains.
After about a week I have seen my teeth get a lot better in color. Not white as I like them but I know over time they will get their. I do also think this is a better way of getting your teeth whitening bleaching them.
