What is smile dental whitening?

Smile dental whitening refers to professional whitening treatments designed to lighten stains inside the enamel.

‍

These treatments use dentist‑approved whitening gels: typically carbamide peroxide or hydrogen peroxide, to break down stain molecules and brighten your natural tooth colour.

‍

It’s stronger, safer and more predictable than shop‑bought strips or DIY kits.

‍

How professional smile whitening works

1. Dental assessment

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

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. Whitening gel application

Peroxide‑based gel penetrates enamel and dissolves deep stains.

4. Gradual shade improvement

Most people see results within 7–14 days, with full brightness after 2–4 weeks.

‍

What results can you expect?

Professional whitening can lighten teeth by several shades, especially if your staining is external (coffee, tea, red wine, smoking).

Results depend on:

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

‍

Internal stains (e.g., tetracycline, fluorosis) may require alternative treatments.

‍
