Whiten my smile
To whiten a smile, a dentist first checks the cause of discoloration, then selects professional bleaching, stain removal, or another cosmetic option.
The short answer
To whiten a smile, a dentist first checks the cause of discoloration, then selects professional bleaching, stain removal, or another cosmetic option. The timing and intensity depend on the tissue involved and the clinical cause.
What can cause your tooth colour to look darker?
Tooth colour may reflect surface stains, natural enamel and dentine colour, aging, trauma, medication, or existing restorations.
What should you do before whitening your smile?
For whitening your smile, start with a dental examination that identifies the tissue involved and the cause. Follow the recommended clinical plan, protect the area from further irritation, and record changes in pain, swelling, colour, or function.
When does persistent smile discolouration need dental care?
Arrange dental care when whitening your smile is persistent, worsening, repeatedly returning, or affecting eating, sleeping, or normal mouth opening. Seek prompt care for facial swelling, fever, uncontrolled bleeding, breathing difficulty, or trouble swallowing.
What should you ask about whitening your smile?
Ask what structure is causing the symptom, which examination or imaging is needed, what treatment options fit the finding, and how you should manage the area during recovery. Ask which changes should trigger an earlier review.
Frequently asked questions
Will cleaning alone whiten teeth?
Cleaning can remove deposits and surface stains, while bleaching is needed to change the shade of natural tooth structure.
Why should restorations be checked first?
Whitening can create a shade mismatch if nearby crowns, veneers, or fillings cannot be bleached.
