The truth is, the cost of professional teeth whitening in the UK can vary widely — and that’s because several factors influence the final price. While it’s natural to consider the cost, it’s also worth asking yourself: can you really put a price on the confidence that comes with a brighter, whiter smile?
On average, professional teeth whitening treatments range from £350 to £1,000. However, the exact amount you'll pay depends on a few key factors, including:
Ultimately, while cost is a consideration, the long-lasting results and boost in self-esteem that come with professional whitening often make it a worthwhile investment.
Professional teeth whitening is a cosmetic dental treatment designed to make your teeth look healthier, brighter, and noticeably whiter.
The process usually involves safely bleaching the teeth to lighten their shade by several levels. When carried out by a qualified dental professional, it’s a safe and effective way to enhance your smile without causing harm to your teeth or gums.
Teeth whitening — also known as take-home bleaching — is a popular and effective way to achieve a brighter, more radiant smile. Over time, teeth can become stained or discoloured due to factors like ageing, coffee, tea, red wine, smoking, or certain medications. This non-invasive treatment is a safe and reliable solution to restore your teeth’s natural whiteness and boost your overall confidence.
The procedure involves the use of medical-grade whitening gel, which is only available through a licensed dentist. This gel is applied using custom-made trays that are carefully moulded to fit your teeth for maximum comfort and effectiveness. You simply wear the trays at home, typically overnight, for up to 14 consecutive days, depending on your dentist’s guidance and your desired results.
Unlike over-the-counter whitening products, professional take-home whitening is tailored to your individual needs and offers safer, more noticeable results. The gradual process also allows for more control over the final shade, helping you achieve a smile that looks naturally white — never overdone.
Whether you're preparing for a special occasion or simply want to feel more confident day to day, take-home teeth whitening is a convenient and proven way to enhance your smile from the comfort of your own home.
In most cases, teeth whitening is considered a cosmetic treatment and is not covered by the NHS. However, there are exceptions where whitening may be offered on medical grounds — for example, to treat tooth discolouration caused by trauma, illness, or certain medications.
If whitening is deemed medically necessary, it would fall under Band 3 NHS dental charges, which covers more complex procedures.
To find out whether you might be eligible for NHS-supported whitening, it’s best to speak directly with your dentist. You can also visit the official NHS website for up-to-date information on dental treatment eligibility and fee bands.
While cheaper DIY teeth whitening kits might seem like a convenient and affordable option, most dental professionals agree they simply don’t deliver the same results as professional treatments.
But why is that?
The difference comes down to the strength of the whitening ingredients. Under UK and EU regulations, over-the-counter whitening kits can legally contain only up to 0.1% hydrogen peroxide, the active ingredient responsible for bleaching stains and lightening tooth colour. This low concentration means that any visible change is often minimal, and results can take a long time — if they appear at all.
In contrast, professional teeth whitening treatments prescribed by a dentist can contain up to 6% hydrogen peroxide — a significantly higher and more effective concentration. These treatments are custom-made to fit your mouth, ensuring even coverage and reducing the risk of gum irritation or enamel damage when used correctly under professional supervision.
Not only do professional kits deliver faster, more noticeable results, but they’re also safer. Dentists can assess your oral health beforehand and make sure whitening is suitable for you — something DIY kits can’t offer.
So while DIY kits might seem like a budget-friendly option, they often fall short in terms of both effectiveness and safety. If you’re looking for real, lasting whitening results, professional treatment remains the gold standard.
