How can you achieve a whiter smile safely?
A whiter smile is usually achieved by treating surface stains, bleaching natural teeth, or changing tooth shape with restorations after an examination.
What can a smile consultation reveal about tooth colour?
A smile consultation separates extrinsic stains from changes inside enamel and dentine, then checks cavities, gum health, existing fillings, crowns, and tooth wear.
Which options can improve your smile’s colour or shape?
A clinician may polish stain, prescribe peroxide trays, provide in-clinic bleaching, or discuss bonding and veneers when colour or shape cannot be corrected by bleaching alone.
When should a dentist assess a dark or painful tooth?
Reduce tobacco and frequent staining drinks, clean between teeth, and seek care for a dark single tooth, pain, bleeding, or a patch that does not polish away.
What should you ask about whitening and restorations?
Ask whether bleaching can address your shade, how restorations will match, and which option preserves the most natural tooth tissue.
Frequently asked questions
How long does a whiter smile last?
The result changes as new surface stain forms and as natural teeth age; maintenance depends on diet, hygiene, and the treatment used.
Are veneers the same as whitening?
No. Veneers or bonding alter the visible surface or shape, while bleaching changes the colour of natural tooth tissue.
