How Much Does Teeth Whitening Cost in the UK?

Wondering about teeth whitening cost in the UK before you book? It is a sensible question, and the honest answer is that prices vary quite a bit depending on the type of treatment and who provides it.

Here is a clear guide to what professional teeth whitening costs, what affects the price and why the cheapest option is not always the one that delivers.

How much does teeth whitening cost in the UK?

Professional teeth whitening in the UK typically ranges from around £150 to £700, depending on the type of treatment and the practice. Dentist-prescribed take-home kits tend to sit in the middle of that range, while in-chair or combined treatments sit higher. Shop-bought kits are cheaper still, but they are a very different product, which we will come to.

What affects the cost of teeth whitening?

A few things shape the professional teeth whitening cost you are quoted.

• The type of treatmentTake-home whitening, in-chair whitening and combined approaches are priced differently.
• Custom-made traysTrays moulded to your teeth cost more than one-size-fits-all trays, but they deliver a more even result and protect your gums.
• The strength of the gelPrescription-strength gel, which can only be provided by a dental professional, is more effective than the weaker formulas sold over the counter.
• Dentist supervisionHaving your whitening planned and checked by a dentist is part of what you are paying for, and part of what keeps it safe.

Why professional whitening costs more than shop kits

It is tempting to compare a dentist teeth whitening cost with a supermarket kit and wonder why there is such a difference. The answer is that they are not the same thing. In the UK, teeth whitening can only legally be provided by a registered dental professional, and the gel they can prescribe is considerably stronger than anything sold over the counter. You are also paying for custom trays, an assessment of whether whitening is right for your teeth, and a professional keeping an eye on your progress. That combination is what delivers a noticeable, even result safely.

Is professional teeth whitening worth the cost?

For many people, yes. A brighter smile is something you see every day, and professional whitening tends to deliver more reliable results than DIY kits, with far less risk of uneven shade or gum irritation. Whether it is right for you comes down to your goals and your teeth, which is exactly what a consultation is for.
