Professional white crest
Professional Crest whitening uses peroxide to lighten natural teeth, but suitability depends on gum health, enamel, sensitivity, and existing restorations.
The short answer
Professional Crest whitening can lighten natural tooth colour when used as directed, but it cannot whiten fillings, crowns, veneers, or damaged enamel.
What is the direct answer?
What does this question mean?
Crest whitening products use peroxide-based chemistry to break down some stain molecules within tooth structure. The result depends on the type of discoloration and the condition of the enamel and gums.
What can you do next?
Read the product directions, keep gel or strips off the gums, use a sensitivity toothpaste if appropriate, and stop if you develop significant irritation. A dental examination is useful before whitening when you have decay, cracks, gum disease, or unexplained colour change.
When should you seek dental care?
Seek dental care for pain, cavities, bleeding gums, enamel defects, or a single darkening tooth before whitening. Persistent sensitivity or gum burning also needs review.
What should you ask the dentist?
Ask whether the discoloration is surface stain, internal tooth colour, decay, fluorosis, trauma, or a restoration, and whether whitening is suitable for your enamel and gums.
Frequently asked questions
Can Crest whitening fix a grey tooth?
A grey tooth can have an internal cause such as pulp injury, so it should be examined before whitening.
Why did my gums turn white?
Whitening material touching the gum can temporarily irritate it. Follow the product instructions and contact a clinician if it persists.
Can whitening repair enamel damage?
No. Whitening changes colour; it does not rebuild lost enamel or seal a defect.
