Is teeth whitening available on the NHS?
No. Teeth whitening is a cosmetic treatment and is not funded by the NHS. The NHS covers only clinically necessary dental treatment. Whitening a healthy but discoloured tooth is not clinically necessary and therefore falls outside NHS provision entirely. All teeth whitening in the UK is self-funded.
Professional whitening options and costs
In-chair Zoom whitening — £350–£600
Zoom is the most widely recognised brand of in-office whitening in the UK. The dentist applies a high-concentration hydrogen peroxide gel (25–40%) to your teeth, activates it with a special light, and repeats for 3–4 cycles over 45–60 minutes. Results are immediate — typically 6–10 shades lighter in one visit. Most Zoom treatments are followed by a custom take-home tray kit for maintenance.
Laser / LED whitening — £300–£800
Uses similar peroxide concentrations to Zoom, activated by a laser or LED lamp rather than the Zoom-specific light. Results and duration are comparable. Price variation is wider — budget providers charge from £300, premium practices charge £700+. Be cautious of very cheap "laser whitening" marketed by beauty salons, which is illegal in the UK unless performed or supervised by a dentist.
Dentist-supplied home trays — £150–£400
Custom-fitted silicone trays are made from impressions of your teeth. The dentist provides a course of whitening gel (10–16% carbamide peroxide, legal for home use). You wear the trays for 1–2 hours per day or overnight for 2–4 weeks. Results are gentler than in-chair but can be equivalent over time. Take-home trays are the best value for patients who are not in a hurry.
Combined treatment — £450–£700
Many practices offer an in-chair session followed by a take-home tray kit for top-ups. This is often the best result — the in-chair session gives instant lift, and the trays allow you to maintain and extend the result at home.
Why are prices so variable?
- Whitening agent concentration: professional-grade (6–40% hydrogen peroxide) vs OTC (under 0.1% in EU-regulated products sold in the UK)
- Brand: Zoom vs Enlighten vs Boutique vs generic
- Location: central London adds 30–50% to prices
- Tray quality: custom-fitted trays deliver gel more accurately than stock trays
- Follow-up gel included: some packages include extra gel tubes; others charge per syringe (£15–£30 each)
How long does whitening last?
Professional whitening typically lasts 1–3 years before a noticeable relapse occurs. This depends heavily on diet (coffee, red wine, tea, turmeric) and tobacco use. Occasional home top-ups (1 night per month with your existing trays and a new gel syringe) can extend results indefinitely. Most patients top up once or twice a year at a cost of £30–£80 per course.
Sensitivity and safety
Tooth sensitivity during whitening is the most common side effect, affecting around 30–40% of patients. It is temporary — usually resolving within 24–48 hours of stopping treatment. Sensitivity is managed by using a lower-concentration gel, spacing out sessions, or using a sensitivity-reducing gel (e.g., Tooth Mousse). Professional whitening by a dentist is safe; non-dental whitening services (beauty salons, online kits with illegal concentrations) carry risks of chemical burns and permanent sensitivity.
OTC vs professional whitening
| OTC kits (£10–£50) | Professional (£150–£800) | |
|---|---|---|
| Peroxide concentration | Under 0.1% | 6–40% (dentist-supervised) |
| Whitening effect | Mild (1–2 shades) | Significant (6–10 shades) |
| Custom-fit trays | No | Yes (home kits) |
| Safety monitoring | None | Dentist screens for suitability |
| Result speed | 3–6 weeks | 1 hour to 4 weeks |
Frequently asked questions
How much does teeth whitening cost in the UK?
In-chair professional whitening costs £350–£800. Dentist-supplied home trays cost £150–£400. Over-the-counter pharmacy kits cost £10–£50 but deliver much more limited results.
Is teeth whitening available on the NHS?
No. Teeth whitening is a cosmetic treatment and is not funded by the NHS in any UK nation.
Is it safe to whiten your teeth?
Yes, when performed by or under the supervision of a dentist using properly regulated products. Peroxide concentrations above 0.1% may only be used in the UK by dental professionals. Avoid beauty salon whitening — it is illegal and potentially harmful.
How white will my teeth get?
Most patients achieve 6–10 shades lighter with in-chair Zoom or a full home-tray course. Teeth with grey or tetracycline staining respond less well than yellow/brown staining. The dentist can give you a realistic expectation at consultation.
Will whitening work on crowns, veneers or fillings?
No — whitening gel only works on natural tooth enamel. Existing restorations will not change colour. If you have prominent white restorations that you want to match, discuss the order of treatment with your dentist — whiten first, then replace the restorations to match.
How often can I whiten my teeth?
In-chair whitening: no more than twice a year for most patients. Home trays: a full course once or twice a year, with single-night top-ups monthly. Excessive whitening can cause permanent sensitivity.
