People can whiten their teeth at home by using over-the-counter bleaching systems that come in the form of adhesive strips, trays and paint-on formulas, notes WebMD. Toothpastes and mouthwashes are also available to maintain the effects of stronger whitening methods.
The best and fastest teeth bleaching services are available from dentists, but these often cost several hundred dollars and are unaffordable for many people. Generic bleaching trays available at drugstores are designed to mimic the trays applied at dental offices, but the home versions are not as specialized and do not prevent bleaching solutions from irritating the gums and causing pain. To avoid this, WebMD recommends waiting at least 30 minutes after brushing teeth to apply trays or strips so the teeth and gums are not raw from toothpaste detergents.
People who are especially sensitive to trays and adhesive strips should try paint-on bleaching solutions, as they cause less irritation. However, this method is not as effective at whitening and may only lighten teeth by a couple of shades. The same is true of whitening toothpastes, but they do not work as well unless an oscillating toothbrush is used for at least two minutes. WebMD also suggests taking advantage of makeup tricks to create the appearance of whiter teeth, such as wearing a true red lipstick without blue or orange undertones.
