New to whitened teeth, is it strange to be able to see my tongue through me teeth?

Only within the last year have I REALLY been on top of cleaning my teeth well. I'm just making sure its not a symptom of something being wrong or anything. When I put my tongue to the inside of my bottom teeth, I can see a color difference through me teeth, which appears to be my tongue.
