It is important to have healthy teeth when carrying out whitening procedures.
It is important for patients to ensure they have good oral health before embarking on a course of teeth whitening, it has been claimed. 
Dolph Henderson wrote in a piece for Ozcar Guide that teeth whitening treatments can be simple and effective ways to improve the appearance of a person’s smile. However, it is crucial they have strong underlying dental health to make the procedure worthwhile.
Mr Henderson noted: “Crowns and fillings will not change colour over the teeth, so it is sometimes advisable to change them at the end of treatment so that their colour matches the new shade of your teeth.”
Elsewhere, Cosmetic Dentistry Guide recently reported a new desktop lamp has been created that promises to whiten a person’s teeth.
The maker of the Desktop Teeth Whitener Lamp claims the device can help whiten teeth by up to five shades through just half an hour’s use each day. It is currently retailing in the UK for £250.
