A. Whitening toothpaste’s are available I have never really been impressed by the results although some people do think they work.  The best way to whiten your teeth is by going to a dentist and having your teeth whitened.  Be aware of products sold over the internet as they are not always fully certified and some products can damage your teeth.  My personal preference is having custom made guards for your teeth made and sleeping in them for about two weeks with whitening gels.
