How does professional whitening lighten natural teeth?

Professional tooth whitening lightens natural teeth with peroxide gel after the dentist checks the teeth and gums.

Why will whitening not change crowns or veneers?

Peroxide breaks down color compounds in enamel and dentine, but does not change restorations such as crowns or veneers.

What happens during a professional whitening appointment?

The dentist records shade, treats disease, protects gums, applies gel, and explains sensitivity care.

When should unusual tooth colour be assessed?

Arrange assessment for severe sensitivity, gum irritation, a dark single tooth, or unexplained color change.

Which types of discoloration can whitening improve?

Ask which discoloration will respond and whether your existing restorations will match afterward.

Frequently asked questions

Can home care replace an examination?

No. Home care supports the mouth, but it cannot diagnose or repair a dental problem.

What determines treatment?

The affected tissue, severity, symptoms, bite, existing restorations, and health history guide treatment.
