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.
Teeth whitening kits from the Dentist produce faster and more effective results because they
contain a stronger peroxide-bleaching agent than whitening kits purchased over the counter.
Another benefit of trays and gels from the Dentist is that the trays are custom made and fit your teeth exactly. Over-the-counter trays are generic sized and could allow the bleaching agent to come into contact with your gums, causing irritation.
