# In-Chair Teeth Whitening — UK price comparison

## Quick answer

In-chair teeth whitening — professional-strength gel applied at the practice, often activated by an LED lamp or laser, in a single appointment of about 60–90 minutes — typically costs £300–£700 in the UK. Packages that add custom home trays for top-ups sit at the top of that range and usually give the most durable result. Whitening is legally dentistry: only GDC-registered dental professionals may perform it, so 'laser whitening' in beauty salons is illegal however clinical it looks. It's cosmetic, never NHS-funded, and only lightens natural teeth — not crowns, veneers or fillings.

## Key facts

- Typical private cost: £300–£700
- Typical UK cost: £300–£700 per session; combined in-chair + home-tray packages at the top of the range
- A visible shade change in a single 60–90 minute appointment
- Legally dentistry — only GDC registrants may perform it; salon 'laser whitening' is illegal
- Temporary sensitivity for 24–48 hours is common; a 'white diet' is advised for the first days
- Results typically last 1–3 years; home trays make top-ups cheap
- Never available on the NHS — whitening is cosmetic
