I need some teeth whitening suggestions/tips?

Tooth whitening: Start with a dental checkup and professional cleaning. Then discuss the many whitening techniques available and what would be best for your situation. They range from in-office whitening, take home bleaching gels in custom trays (my favorite as it's cost effective and you have the trays for future touchups), crest whitestrips, etc.

Bleaching teeth: Avoiding coffee, tea, cherries, blueberries, smoking and other similar foods that cause superficial stains. Using crest white strips can be effective. Whitening toothpastes are just more abrasive and don't really whiten teeth- they just help to scrub off the superficial stain.

See Dentist: Most effective and cost effective treatments provided by your dentist. Whitening strips and whitening toothpaste less effective. Avoid coffee, tea, colas, mustard , saffron, tomato sauce, and other pigmented foods. And most of all, don't smoke.
