Types of teeth whitening
We won't go into too much detail about the different options here, because we have a separate teeth whitening guide which gives a more in-depth look at the different ways to whiten your teeth.
But if you want to understand what teeth whitening costs, you first need to know which procedures are available. All whitening treatments can be broken down into two categories: those which involve a dentist, and those which don't.
Let's look first at the options for getting your teeth whitened professionally.
In-office LED and laser whitening
The most expensive procedure, but also the one that gives the fastest results, involves you sitting in the dentist's office for around an hour. Your teeth are coated with a strong bleaching gel, usually containing hydrogen peroxide, and a laser or LED light is shone on them to accelerate the bleaching process.
Here's a quick look at what to expect as a Zoom whitening patient:
It's possible to get your teeth 2-8 shades whiter in just one session. The procedure is supervised by a trained dentist, and they apply a gum shield to protect your gums from the strong gel, so it is considered very safe. However, there is some likelihood of sensitivity from such an intensive treatment.
How much does laser teeth whitening cost?
You'll pay between £500 and £1,000 for laser teeth whitening treatment at the dentist, depending on the system used and the number of sessions required.
Take-home custom bleaching trays
This treatment is administered by a dental professional in-office, but the whitening process itself takes place at home.
The first step is to have custom trays made to precisely fit your mouth. Then, your dentist will provide you with bleaching gel, again containing peroxide, and will show you how to use it correctly and safely. Treatment takes around two weeks, over which time you should notice a considerable difference in the colour of your teeth. You wear the trays for 2-6 hours per day, according to your dentist's instructions.
What does take-home teeth whitening cost?
Take-home kits for teeth whitening cost around £200 – £400 from dentists in the UK. They are a safe way for patients to get brighter, whiter teeth from home.
Combination teeth whitening treatments
If you want instantly whiter teeth and more sustained cosmetic results, you can combine these two options. Some systems require you to complete your treatment at home first, whereas others begin with the chairside whitening session.
What does Enlighten teeth whitening cost?
Enlighten is one teeth whitening brand in the UK which offers combined in-office and take-home whitening treatment. A full course of Enlighten teeth whitening costs around £400 – £750 in the UK.
Philips Zoom is a well-known brand which offers a similar package, but you can also get either treatment separately from dentists that use Zoom whitening.
Whichever professional teeth whitening option you choose, you'll need a dental consultation before you begin. Your dentist will check that you don't have any untreated cavities which might need to be filled first. They'll also look for signs of gum disease, which might make you a poor candidate for tooth whitening.
At-home whitening kits
So, what about teeth whitening treatment which is not overseen by a dentist? Home teeth whitening kits are widely available over-the-counter in pharmacies and online. They usually contain whitening gel, a mouth tray, and sometimes an LED activating light.
Manufacturers are not allowed to use hydrogen peroxide in over-the-counter kits in the UK (at least not in a concentration strong enough to do anything). Therefore, home kits usually contain other peroxide-based ingredients, although some are completely peroxide-free.
What do they cost?
If you look online you'll find these products costing anywhere from £20 to £150 or more. We recommend choosing one which is made in the USA or Europe, where manufacturing standards are high and cosmetic products are closely regulated.
One of our top picks for a teeth whitening kit is Smile Avenue. There are a few reasons why we think this is a great choice if you can't afford the cost of teeth whitening treatments with a dentist:
- Smile Avenue's teeth whitening gel is designed to avoid sensitivity and actively remineralises teeth as you use it.
- You paint the gel directly onto your teeth in a thin layer, so there is no risk of excess gel squirting onto your gums and damaging them.
- The mouthpiece has a built-in LED light for even coverage.
- Very affordable gel refills are available.
- The kit comes with a money-back guarantee.
Another popular option is Snow teeth whitening. Their kits are made in the USA with a strong peroxide formula, and contain enough gel for a whole year's worth of whitening.
Other whitening products
You can also purchase teeth whitening strips, pens, and toothpastes in the UK. These function fine as stain removers, but they don't contain the same strong ingredients that you'll find in professional teeth whitening gel, and so you shouldn't expect drastic whitening results.

Results may vary; some safety concerns
What does NHS teeth whitening cost?
Teeth whitening on the NHS is only offered in certain circumstances where it is considered a medical need. No type of cosmetic dentistry is covered by the NHS.
For example, if your tooth nerve has died and one tooth is considerably discoloured, or you have tetracycline teeth stains, you may get treatment on the NHS. In this case, treatment would be via internal bleaching. Each case is assessed individually, so speak to your dentist to find out if you might be able to get teeth whitening on the NHS.
If you are eligible for teeth whitening on the NHS, you will probably pay the Band 3 treatment fee, which varies depending on where you live in the UK. See full NHS dental fees.
Does dental insurance cover teeth whitening costs?
Most insurance policies don't cover any kind of elective cosmetic dentistry such as professional tooth whitening. If you are being treated as an NHS patient, however, this will be covered under your normal NHS treatment policy allowances.
Some dental payment plans, arranged directly with a local dentist or a chain of clinics, offer a fixed percentage discount off all treatments including cosmetic whitening. It's probably not worth starting a payment plan for this saving alone, but it could be a bonus if you already have this kind of plan in place. Your dentist might also agree to let you pay in instalments.
Other dental financing options are available, including dental loans. However, you should carefully consider whether it's worth taking on debt for cosmetic dental work.
In-office vs. Over-the-counter whitening products
When choosing a teeth whitening procedure, cost is not the only consideration. Here are some other important factors that may influence your decision, some of which we already touched on above:
- How long the treatment takes
- How quickly teeth become brighter
- Whether it causes any sensitivity
- Whether the procedure is safe
- What the risks are
- How long the results will last
Generally speaking, the stronger the concentration of peroxide used in the bleaching gel, and the more intense the procedure, the greater the likelihood of sensitivity.
That said, dentistry manufacturers are working all the time to develop new technologies and ingredients which deliver better results with less discomfort. One benefit of visiting a dental practice, whether for an in-office procedure or take-home trays, is that you can contact your dentist at any time if you have concerns about tooth pain or sensitivity. You don't get the same level of care from buying a product online.
How to keep your teeth white
With teeth whitening prices so high, you'll want to do what you can to prolong your results. Brushing and flossing daily will help a lot, and you may want to use a teeth whitening toothpaste to keep surface stains away.
You can also try to avoid some foods and drinks which are known to stain teeth, such as:
- Tea (including green tea)
- Red wine
- Tomato sauces
Our article about yellow teeth causes and treatments goes into more detail about these and other culprits.
But over time, no matter how careful you are, stains will reappear and you might find yourself wanting to get your teeth whitened again.
In this case, you may be able to purchase ‘top-up' whitening gel refills to use with the tray you already purchased – whether via a dental practice or as part of an over-the-counter kit. If you were happy with your results first time around, you can simply repeat the treatment periodically. You may not need to do it for as long each time, since some of the original whitening effect should still be present.
Of course, you can also return to your dentist for another chairside whitening session, but it's advised to limit this intensive procedure to once a year to avoid damaging your teeth.
You probably already knew that the cost of teeth whitening treatment in the UK varies greatly, but now you have a better understanding of what you're getting for your money.
Ultimately, you'll have to choose the procedure that's right for you depending on your budget, how white you want your teeth to become, and how quickly you want to achieve that shade.
If you have never whitened your teeth before and you are concerned about sensitivity or ending up with unnaturally white teeth, you'll probably be best with a home kit which whitens teeth gradually. Smile Avenue is one which we recommend for its gentle formula and smart application.
On the other hand, if you're hoping for instantly white teeth and you want to achieve the whitest shade possible, you should head to a dental practice offering your preferred brand. You may want to consider veneers or other cosmetic dentistry if you want to truly transform your smile.
In any case, it's best to have a dental consultation before beginning whitening treatment, since there is a greater risk of pain and sensitivity if your teeth and gums are not in good shape.
How much does at-home teeth whitening cost?
This depends on how white you want your teeth to be. If you choose a cheap teeth whitening kit, you can achieve some degree of whitening for around £20. A professional whitening kit will give stronger results for around £50-£100.
For the strongest whitening gel, you'll need to visit a dentist and get a take-home kit, which will cost upwards of £200.
What is the cost of teeth whitening at the dentist?
In-office teeth whitening costs £350 – £1,000, while a take-home kit prescribed by a dental professional costs from £200 – £400 on average. Both are a proven way to get whiter teeth. That said, laser whitening usually gives the most significant difference.
What is the cheapest way to whiten teeth?
You can buy a whitening toothpaste for a few pounds. It might remove some surface stains, but it won't make too much difference to the natural colour of your teeth. So, it's unlikely to give you that brighter, whiter smile you desire.
Over-the-counter treatments like whitening kits will give better results, and are probably a good place to start if the cost of whitening your teeth at the dentist seems too high.
