Do you know a good teeth whitening technique?

In office trays: Using custom fitted trays fabricated in the dental office is one of the best treatments to whiten teeth. The trays fit very closely to the teeth and the permits the whitening solution to have contact with the tooth for longer times.

Teeth whitening: Over the counter whitening strips can be helpful, though they only cover the front 6 teeth and some people find them cumbersome. Custom made trays made by a dentist are more effective because they use a higher concentration of whitening solution than what is available over the counter. Avoid anything that requires a rinse with an acid "pre conditioner"-it will erode the enamel, make teeth painful.
