Darker teeth can be lightened with special bleach, which can be applied in the dental chair or at home.
Customised plastic trays are made to fit specifically to the shape of your teeth and act as a reservoir for the bleach. After two weeks of night application at home, you should notice a significant difference in the brightness of your teeth. This treatment may not work for some types of discolouration.
Teeth that are discoloured following root canal treatment can sometimes have their original colour returned by bleaching inside the tooth. This can only be carried out in the dental chair.
