In general, you can keep teeth whitening costs down by choosing products with a lower concentration of hydrogen peroxide. Teeth whitening strips with lower concentrations of whitening agents can minimize teeth whitening costs—they usually have more strips per pack and cost less than the more potent whitening products. And many people find the lower concentration products work better on sensitive teeth, so they are able to keep teeth whitening costs down and reduce their chances of suffering tooth sensitivity or gum irritation.
The Extra Benefits Offset Teeth Whitening Costs
Another way to look at teeth whitening costs is in terms of the costs of not whitening your teeth. In a 2007 study by researchers at Loyola Marymount University (need citation), people with whiter teeth were perceived as more attractive, and they received longer interviews and higher salary offers compared to before their teeth were whitened. In this study, the results suggest that teeth whitening costs are worth it, because a clean, bright smile will give you more confidence and may improve your chances in job interviews, on the dating scene and in everyday communications. Start by buying the best quality whitening products and using them no more frequently than the package directs, and you’ll keep teeth whitening costs down.
