I want whiter teeth
Whiter teeth may require cleaning or peroxide whitening, depending on the stain and existing restorations.
The short answer
Cleaning removes plaque, calculus, and some external stain, while bleaching changes the color of natural tooth structure through peroxide chemistry. Veneers, crowns, and fillings keep their original shade, so treatment may need to be coordinated with restorations. Use fluoride toothpaste, clean between the teeth, and avoid tobacco and frequent staining drinks if they darken the surface. Have a dentist examine decay, erosion, cracks, gum inflammation, and restorations before starting a whitening product.
What daily habits can help keep teeth looking whiter?
Use fluoride toothpaste, clean between the teeth, and avoid tobacco and frequent staining drinks if they darken the surface. Have a dentist examine decay, erosion, cracks, gum inflammation, and restorations before starting a whitening product.
When should you have an examination before whitening?
Seek an examination before whitening if there is toothache, bleeding, exposed root surface, a dark single tooth, or untreated decay. Stop a whitening product and arrange review if pain or gum burns persist.
When should tooth discolouration be assessed by a dentist?
Ask whether cleaning alone is enough, what shade change is realistic for your natural teeth, and how restorations will match afterward.
How will whitening affect fillings, crowns, and veneers?
Whitening gel is applied to natural tooth structure, not to ceramic or composite restorations.
