Google displays sample posts

Hi!

We just built our website using WordPress. Everything good so far ??

But when I google my website, google show links to my different menu pages and also links to sample posts which doesn’t exist anymore. Is there a way to make google NOT show these sample posts? It doesn’t loo professional when you see it this way.

See example here:
https://www.google.com/search?q=Vendela%20%26%20Valentin&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:sv-SE:official&client=firefox-a&source=hp&channel=np

Does anyone know how I can change this?

Thanks!
