Teeth whitening has become extremely popular over the past several years. It is a great way to improve your appearance; it is reasonably priced; non-surgical; and non-invasive.
The treatment involves wearing custom made trays which carry the whitening agent. The length of time they are worn daily varies from thirty minutes to overnight. The treatment takes approximately seven to ten days, depending on the shade you require.
Typically, one would expect up to seven shades whiter. Most people are suitable for this treatment, however, you should speak to your Dentist and discuss all options.
