Opalescence is a peroxide-based tooth-bleaching system delivered through dentist-supervised in-office or take-home methods.
The short answer
Opalescence is a peroxide-based tooth-bleaching system delivered through dentist-supervised in-office or take-home methods. The timing and intensity depend on the tissue involved and the clinical cause.
How does peroxide bleaching change tooth colour?
The system uses a peroxide gel that breaks down stain molecules in natural enamel and dentine; the exact product and tray method determine how it is used.
What should you do before starting Opalescence bleaching?
For Opalescence bleaching, 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 should bleaching be assessed by a dentist?
Arrange dental care when Opalescence bleaching 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 Opalescence treatment?
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
Can I use more gel to whiten faster?
Use only the amount and schedule provided for the selected product, because excess gel can irritate the gums and increase sensitivity.
Can Opalescence whiten a crown?
No. Bleaching changes natural tooth structure, not ceramic, metal, resin, or implant materials.
