What is professional teeth whitening?

Professional whitening is a dentist‑supervised treatment that uses peroxide‑based gels to lighten stains inside the enamel.It is stronger and more predictable than shop‑bought strips or DIY kits.

It targets stains caused by:

• coffee and tea
• red wine
• smoking
• everyday food pigments
• natural ageing

‍

Dentists tailor the strength and method to your teeth, making it safer and more effective.

‍

How professional whitening works

1. Dental assessment

A dentist checks your teeth and gums to ensure whitening is safe and suitable.

2. Custom whitening trays or in‑clinic treatment

Depending on your needs, you may receive:

• custom‑made whitening trays
• in‑clinic whitening sessions
• or a combination of both

3. Peroxide gel application

The gel breaks down stain molecules inside the enamel.

4. Gradual shade improvement

Most people see noticeable results within 7–14 days, depending on stain type and consistency.

‍

What results can you expect?

Professional whitening can lighten teeth by several shades, especially if your staining is external.

Results depend on:

• starting shade
• stain depth
• enamel thickness
• consistency of use
• lifestyle habits

‍

Internal stains (e.g., tetracycline, fluorosis) may not respond as well.

‍

Professional whitening vs other options

Is professional whitening safe?

Yes - when supervised by a dentist.

However, temporary side effects may include:

• mild sensitivity

• dryness during treatment

‍

These usually settle within a few days.

‍

Who professional whitening works best for
