Professional whitening: in-office or take-home kit? The complete guide

Whiter teeth in one hour or two weeks? Professional whitening comes in two main forms: in-office treatment and take-home kits. Both work — but in different ways for different needs.

In-office whitening

The dentist applies high-concentration hydrogen peroxide gel (35-40%) to the teeth, activated by LED or laser. Duration: 60-90 minutes. Result: 6-10 shades lighter in a single session.

• Cost in Albania: €150–200 | In Italy/UK: €400–700

Take-home kit

Custom-fitted trays with lower-concentration gel (10-22%). Worn for 1-2 hours per day for 10-14 days. More gradual, natural-looking result.

• Cost in Albania: €80–120 | In Italy/UK: €250–400

How long does whitening last?

With good oral hygiene and avoiding excess coffee and wine, professional whitening lasts 1-3 years.

Does whitening damage teeth?

No, when done correctly. Hydrogen peroxide acts on enamel without structural damage. Temporary sensitivity is normal and disappears within 24-48 hours.
