other than getting my teeth whitened, which I will do eventually but for now I want to know if I can at all avoid my teeth looking yellowish when wearing bright lipgloss.

Are there any specific shades that make teeth look wider? I heard if you get one that’s darker than your natural color, it will make your teeth look whiter. True? I’m thinking about buying one of these glosses (see link) and can’t decide which shade to get! Opinions please? I have fair skin, light to medium brown hair, and average size/color lips.

Actually, my teeth are already white so I guess it’s not a big deal. The thing is, I don’t want to wear a gloss that makes them look really white, and then wear a different shade the next day that makes them look darker. That’d be wierd and gross! Help
