A smile is a huge part of any first impression, and keeping your teeth looking pearly white could be easier than you think. For example, did you know that the colour of lipstick you choose can have a huge effect on how white your teeth look?

S! TV headed along to the Listerine Wear Your Smile event to get some more expert whitening tips and to chat to Xposé's Lisa Cannon about how she keeps her own smile bright at all times.

If you're looking for a simple and effective whitening system, try Lisa's favourite, the new Listerine Advanced White multi-action mouthwash which makes teeth appear brighter and whiter in just two weeks.
