Teeth lose their whiteness for a number of reason. In her younger years, my friend had smoked and also been a coffee and soda drinker. Her teeth were now stained.

There are several ways that you can brighten your smile and whitened your teeth.

If you have time, brushing with baking soda or peroxided may help whiten teeth. You could also brush with teeth whitening toothpaste. However, that could takes weeks or months to see a real difference.

If you want whiter teeth in seven days you have basically two options.

Option #1: A visit to the local dentist for a tooth whitening session.

The drawback is that it is expensive and many do not like the dentist office. You will see good results though.

Option #2: Use a at home teeth whitening kit.

These are vastly cheaper than visiting the tooth specialist. It will take some learning, but the results can be spectacular. Many individuals, including my friend have whitened their teeth with these at home teeth whitening kits. They use teeth whitening gel and a tooth whitening light.

If you are skeptical, many offer free trials. Try it and see the results. You will get whiter teeth in 7 days.
