If your smile makes your shirt look brighter, I suggest you start using a tooth whitening kit. Don't rely on relatives - they lie. "It's nothing darling, just a mild discoloration. You're beautiful just as you are."

Teeth are not what they may seem to the unaided eye. If your tooth discoloration is caused by the yucky stuff trapped in your enamel pores, whitening kits can help.

So now say 'bye-bye' to your yellow dirty teeth. It's time for beautiful white teeth.
