Teeth whitening involves bleaching your teeth to make them lighter. It can’t make your teeth brilliant white, but it can lighten the existing colour by several shades.Want a brighter smile? When it comes to tooth-whitening, you’ve got two options: in-office-based teeth bleaching, or at-home care.Both tooth-whitening options use peroxide-based bleaching agents. At-home systems contain from 3% to 20% peroxide (carbamide or hydrogen peroxides). In-office systems contain from 15% to 43% peroxide.
This all depends on the reasons why your teeth became discoloured, and on your lifestyle choices but the results may last for up to two years before you need another treatment. We will give you plenty of advice on how to maintain the results for longer. Avoiding highly coloured foods, quitting smoking and having a good oral hygiene routine will all help your teeth remain whiter for longer.
