Crest intensive professional effects
Intensive whitening can lighten natural teeth, but results depend on peroxide exposure, tooth structure, stains, and sensitivity.
The short answer
Whitening products use peroxide to alter colored molecules in enamel and dentin. Fillings, crowns, and veneers do not change color, and decay or gum disease should be assessed first.

What is the direct answer?
What does this question mean?
Use the product exactly as directed and discuss tray fit and sensitivity with a dentist. Stop if gum irritation or severe sensitivity occurs.
What can you do next?
Arrange an examination to identify the cause and follow the product or care instructions given for your condition. Do not delay urgent care when swelling, fever, breathing difficulty, or persistent pain is present.
When should you seek dental care?
Seek prompt dental care for worsening symptoms, swelling, fever, trauma, persistent lesions, or difficulty eating, swallowing, breathing, or opening the mouth.
What should you ask the dentist?
Ask what structure is affected, which treatment addresses the cause, and what warning signs should prompt urgent review.
Frequently asked questions
Will whitening change a crown?
No. Whitening affects natural tooth structure, so a crown may remain its original shade.
What should I do while arranging care?
Keep the area clean, follow suitable instructions, and seek urgent help if symptoms worsen or affect breathing or swallowing.
