Ndoki - Whitening strips contain peroxide used to bleach your tooth enamel. The FDA only allows products to contain 16% or less of carbamide peroxide, or 6% hydrogen peroxide.
Teeth whiteners can cause a temporary increase in sensitivity, or irritation of gums and soft tissues. Especially potent whiteners can cause an "overbleaching effect" and bleaching is not meant for people with already sensitive teeth.
Also, although not part of your original question I should add a quote from wikipedia: "recent study by Kugel et al. showed that nearly half the initial change in color provided by an intensive in-office treatment (i.e., 1 hour treatment in a dentist's chair) may be lost in seven days. Rebound is experienced when a large proportion of the tooth whitening has come from tooth dehydration (also a significant factor in causing sensitivity). As the tooth rehydrates, tooth color 'rebounds' back toward where it started."
From personal experience no teeth should be as white as they show on TV, and any small benefit you may get from tooth whitening products isn't worth the pain/money. Just brush your teeth (I find baking soda toothpastes the best for keeping teeth 'white') and just be happy with how your body is naturally.
