Teeth Whitening?

My teeth have gotten pretty stained from coffee, wine, and smoking. Any suggestions on how to take care of this AS quickly as possible. I'm going on a big trip in 11 days, and I want a WHITE smile. I already have bleaching trays from the dentist, so if you have a bleaching gel to suggest... that would be great. I don't want the kind that you have to keep on over night. Just for 30 min. Also if you know of any home remedys. Also from EXPERIENCE only... how much does it cost (generally) to get them whitened in the dental office?? I know I shouldn't smoke.... blah blah blah!

In addition to bleaching solution, whitening strips are increasingly being used as a preferred tooth whitening product. For instance, you are now able to get your hands on a set of Crest Whitestrips Supreme from any convenience store. The flexible, invisible strips are coated with an enamel-safe tooth bleaching gel. To whiten your teeth, you simply place the strips on your teeth and wear them for about 15 to 30 minutes each day. After a period of about 21 days, you should be able to see a significant difference on the brightness of your teeth. The most common option used as homemade teeth whitening agent is baking soda, which has a mild bleaching action. Given that it is used in baking, it also implies safety. Baking soda is sprinkled on the toothbrush, and teeth then cleaned using a gentle, circular motion. Care should still be taken though, especially for people with gum sensitivity. Old wives' recipes often state that a paste of baking powder, a little salt, and a few drops of white vinegar, works effectively. Salt, used exactly as baking soda, is also touted as being a good teeth whitener. However, it might just be its osmosis, dehydrating action that makes teeth appear whiter, since dehydrated teeth look whiter. Lemon juice is often used, but it had high acidic levels, so teeth can weaken in the long run. Other natural, fruit options regard rubbing the inside of an orange peel on the teeth. A strawberry cut in half and the inside rubbed on teeth also works. Mashed strawberry can also be applied with a toothbrush. Apple cider vinegar is also said to be effective. Dried orange rind, and walnut bark, is also good. For other effective home teeth whitening solutions, you may wish to read about them here : http://teeth-whitening.my-fashion-house.…
