Why do some Wandsworth practices list under half the median?
6 of 43 published prices are below £192: Smiles@Preventivedental.com (£80), Riverside Dental Practice (£90), Battersea Dental Practice (£95). A figure this far below the borough median is often a narrower product than the rest of the table (a single session, a top-up, or an introductory offer) — check what the practice's fee guide includes before comparing.
Why does the same practice name appear twice?
1 name recurs (Balham Dental Studio / Balham Dental Care). The CQC registers each location separately, and some practices hold two registrations at one address. Each row links to its own CQC registration and each row is counted in the figures above; if the pair is one practice, read it as a single price point.

A low figure is a real published fee, not a quote — complexity can change the price. Always confirm. How we verify
Professional teeth whitening uses hydrogen or carbamide peroxide to lighten teeth. In the UK it is legally only available through a registered dental professional.
Whitening is not permanent. In-chair results typically last one to three years; professional home whitening six months to two years; shop-bought kits a few months at most. A non-smoker who avoids coffee and keeps up hygiene appointments holds results far longer than the averages suggest.
The main things that shorten results are coffee, tea, red wine, dark sauces, berries and smoking. Acidic food and drink weaken enamel over time, making teeth more prone to re-staining. Most dentists suggest a top-up every 6–12 months — if you keep your trays, that usually means a fresh gel syringe (£30–£80) rather than a full course again.
Teeth whitening is the practice of dentistry under UK law — confirmed by the High Court in GDC v Jamous (2013). Only GDC-registered professionals (dentists, dental hygienists, dental therapists, or clinical dental technicians working to a dentist's prescription) may legally perform it.
On peroxide concentration: products releasing 0.1% or less can be sold to consumers (the strips and kits in shops, largely ineffective); 0.1%–6% is restricted to registered professionals; above 6% is banned outright for cosmetic use. Whitening is not permitted for anyone under 18.
If a non-registered person applies whitening gel to your teeth — a salon, a "whitening bar", a mobile provider — they are breaking the law regardless of the product, and the GDC prosecutes these cases with unlimited fines. A BBC investigation in late 2025 found a 26% year-on-year rise in reports of illegal whitening, with providers buying gel far above the legal limit. Before booking, look your dentist up on the free GDC register at olr.gdc-uk.org.
Ask what's included. A £300 quote covering consultation, trays, gel and follow-up beats a £200 quote that charges separately for impressions and each gel syringe. Get the total in writing first.
Keep your trays. Custom trays last years — for a top-up you only buy fresh gel (£30–£80), far cheaper than a new course.
Order matters with other treatments. Whiten before veneers, bonding or crowns — restorations are colour-matched and won't change shade later. Whiten first, wait two weeks for the shade to settle, then match any restorations. See our veneers cost guide and Invisalign cost guide.
