editing teeth?

[leftypony]

My friend has very yellow teeth ... being the good friend that I am, I'd like to brighten up her smile without the cost of bleach trays. Any tips for achieving a natural looking bright smile with photoshop?

This is just a snap shot that I thought would be easy to practice on.
