What is teeth whitening?

Teeth whitening is a dentist‑led cosmetic treatment that uses safe whitening gels to break down stains and lighten the natural shade of your teeth.

Modern whitening is:

• technology‑driven
• accessible
• convenient
• clinically safe
• designed for predictable results

‍

Whitening works on both surface stains and deeper discolouration inside the tooth.

‍

How whitening works

Whitening gels contain peroxide, a clinically safe ingredient that breaks down stain molecules.

The science behind whitening

• Peroxide enters the enamel
• Oxygen molecules break apart stains
• Tooth colour becomes lighter
• Enamel remains intact

‍

Whitening does not damage enamel when used correctly.

‍

Types of teeth stains

1. Surface stains (extrinsic)

Caused by coffee, tea, red wine, smoking and everyday foods.

2. Deep stains (intrinsic)

Caused by ageing, medication, trauma or long‑term discolouration.

3. Natural tooth colour

Everyone has a unique baseline shade — whitening simply brightens it.

How whitening works

Is teeth whitening safe?

Yes, when supervised by a dentist.

Professional whitening uses regulated gels that:

• protect enamel
• minimise sensitivity
• deliver predictable results
• avoid gum irritation

‍

DIY kits without dentist guidance can cause burns, uneven whitening or sensitivity.

‍

How long whitening takes

Treatment length depends on the method:

• Professional whitening: 1–2 sessions
• Home whitening: 1–3 weeks
• Whitening strips: several weeks

‍

Dentist‑led whitening is the fastest and most reliable.

‍

How long results last

Whitening results typically last:

• 6–12 months with good oral care
• longer with regular maintenance
• shorter if consuming staining foods frequently
