How much does teeth whitening cost in Oslo in 2026?

Dental & Dermal is a combined dental and aesthetics clinic in central Oslo, run by dentist Chenxiao Li. We offer professional teeth whitening with predictable results - and here we give you an honest overview of what it actually costs in 2026.

Price overview: Professional vs. at-home whitening

Teeth whitening prices in Oslo vary significantly depending on the method you choose:

• Professional in-office whitening: 2,900 – 8,000 NOK per treatment
• Take-home kit from your dentist (with custom trays): 2,500 – 4,500 NOK
• Over-the-counter products from the pharmacy: 200 – 800 NOK

At Dental & Dermal, professional teeth whitening starts from 2,900 NOK. This includes consultation, the whitening procedure itself, and a follow-up check. The treatment takes approximately 60–90 minutes and typically delivers 3–8 shades lighter teeth in a single session.

What's the difference between professional and at-home whitening?

Professional whitening uses higher concentrations of bleaching agent (typically 6–38% hydrogen peroxide) combined with LED or laser light to accelerate the process. Results are visible immediately after treatment.

At-home whitening with custom trays from your dentist uses lower concentrations (10–22% carbamide peroxide) and requires daily use for 1–3 weeks. The results are gradual but equally long-lasting.

Over-the-counter products contain very low concentrations and often deliver minimal or temporary results.

How long do results last?

Professional whitening results typically last 1–3 years, depending on lifestyle. Factors affecting longevity:

• Coffee, tea, and red wine stain teeth faster
• Smoking significantly reduces longevity
• Good oral hygiene extends results
• Touch-up treatments after 6–12 months can maintain whiteness

Chenxiao Li recommends an annual touch-up for most patients, which costs significantly less than the initial treatment.

Is teeth whitening safe?

Yes, professional teeth whitening is safe when performed by a qualified dentist. The most common side effects are:

• Temporary sensitivity lasting 24–48 hours
• Mild gum irritation

At Dental & Dermal, Chenxiao Li always conducts a thorough examination before whitening to rule out cavities, cracks, or gum disease that could be aggravated by the treatment.

Who should avoid teeth whitening?

Teeth whitening is not recommended for:

• Pregnant or breastfeeding women
• Children under 18
• Patients with untreated cavities or periodontal disease
• Those with very sensitive teeth without a clarified cause
