Invisalign vs Braces: Compare Pros and Cons with Cost, Speed & Comfort


If you're trying to choose between Invisalign or braces, there's a lot to consider. Cost, speed of treatment, appearance and comfort will all play a part in your decision between clear aligners and traditional fixed braces.

You might be considering clear ceramic braces or lingual braces too, as an alternative to traditional metal.

Is Invisalign better than braces?

We understand that this is an important choice. After all, once you have begun your orthodontic treatment, you can't easily switch to another type of braces.

So here, we're going to look at all the different aspects of Invisalign vs braces, including:

  • What Invisalign and braces cost
  • Which is faster
  • Whether braces work better than Invisalign
  • The practicalities of wearing clear aligners and fixed braces
  • How to decide which is best for you

Let's get started!

Braces vs Invisalign: Similarities and differences

Whether you want to straighten crowded teeth, close a gap in your teeth, or correct a bad bite, the overall goal of braces and Invisalign clear aligners is the same: to bring your teeth into better alignment.

Straighter teeth not only help you feel more confident, but are also easier to care for in the longer term. In more severe cases, orthodontic work can also improve speech and reduce problems like teeth grinding.

All orthodontic treatment works by applying pressure to teeth to gradually move them. But this is really where the similarities between Invisalign and regular braces end.

Traditional braces involve having brackets cemented to each tooth with a wire joining them. Invisalign, on the other hand, involves a series of removable clear plastic aligners which fit snugly over the teeth.

Aligners are harder to notice

Aligners are very difficult to spot, which is why they are also known as ‘invisible braces'. The fact that they can be removed means it's easier to clean your teeth during your treatment.

However, some people find it inconvenient having to wear them for 20-22 hours per day. You're not allowed to eat or drink anything except water while wearing aligners.

Finally, it's important to not that not everybody is a good candidate for Invisalign. Although they can treat around 90% of cases, the most severe malocclusions will require fixed braces (and perhaps surgery).

There's an easy way to check whether you're one of the 90% though: simply take two minutes to fill in Invisalign's Smile Assessment. You'll get your results straight away!

Here's a table summarising some of the key differences between Invisalign and braces:

Traditional braces



Metal brackets and wires are very noticeable.

Clear plastic aligners are almost invisible.

Eating restrictions

Some foods not allowed.

No restrictions when aligners are removed. No eating with aligners in.


Fiddly to clean; require special care.

Clean teeth as normal when aligners are removed.


Usually just regular checkups and adjustments

Aligners can be lost or damaged


£1,500 - £3,000 or more, depending on complexity

£1,500 - £5,500 on average, depending on complexity


Suitable for all cases

Suitable for 90% of cases.

Clear ceramic braces vs Invisalign

Ceramic braces use clear or tooth-coloured material so the brackets and wire are far less noticeable. However, they are still fixed to the front of your teeth so are generally less comfortable and more obvious than Invisalign.

Still, if you're concerned about aesthetics and Invisalign is not an option for you, clear braces are a good alternative to metal. The cost of clear braces and Invisalign is usually about the same.

Lingual braces vs Invisalign

Lingual braces use metal brackets but they are fixed behind your teeth. This makes them, in a way, even less noticeable than Invisalign. Some people find that lingual braces affect their speech or cause tongue sores at first, but this is usually only a temporary problem.

It's often the case that lingual braces cost more than Invisalign – especially if you choose a brand with custom-fitted brackets.

In the following video dentist, Dr David Bloom explains the differences between lingual braces vs Invisalign, to help you decide which one would be the best fit for your lifestyle.

Invisalign are removable, clear aligners, whereas lingual braces are fixed onto the teeth. Each method straightens the teeth, so how do you choose which type to have? Dr David Bloom explains the differences. Make an appointment with Dr David Bloom here:

Invisalign vs braces: Cost

Price is a big factor when deciding which braces are right for you, so what about the cost of Invisalign vs regular braces in the UK?

The first thing to know is that the cost of any orthodontic work will depend on the complexity and duration of your treatment.

Some people need minor tooth movement which can be achieved in under six months. Others need significant correction that requires 18 months or more.

And it stands to reason that the longer your treatment is, the more time you'll spend in your dentist's office and the more materials will be required. This all pushes up the cost.

Putting treatment length aside, we can say that in general, treatment with metal braces is usually available for slightly less than the price of Invisalign. However, many patients are willing to pay a little extra in return for the convenience and discreetness of Invisalign.

The best way to find out the price for your Invisalign treatment is to book an appointment with an Invisalign provider near you. They will do a full assessment and provide a personalised treatment plan. Many providers offer this initial consultation for free, and you can use Invisalign's search tool to see where your nearest dentists are.

Invisalign dentists usually provide metal braces as well, so they will be able to let you know the price for both options.

Invisalign vs braces: Which is faster?

Another common question is whether Invisalign or braces are faster. It's understandable that you want to get your teeth straightened as fast as possible, and in this case, you may want to opt for Invisalign.

This study found that clear aligners do result in faster treatment times as well as less time in the dentist's chair. This can be especially true for less complex cases.

Do braces work better than Invisalign?

Most patients can be treated just as effectively with Invisalign as with metal braces. However, in around 10% of cases involving complex tooth movement, fixed braces will be a better option.

This report states that “Although it is possible to treat complex malocclusions with plastic systems, the results are less accurate than those achieved with fixed appliances.” So, if you have a more complex case, it may be that fixed braces will give a better result.

You can easily check whether you're a good candidate for Invisalign using their free online Smile Assessment. Or, you can book an appointment to visit an experienced Invisalign provider near you. They will carry out a full assessment and advise you on your treatment options.


Having looked at Invisalign vs braces in detail, we can say that Invisalign might be a better choice if:

  • You want the least noticeable option
  • You need mild or moderate tooth movement
  • You'd prefer to be able to eat what you like and clean your teeth as normal
  • You have the willpower to wear your aligners as directed

On the other hand, fixed braces may be better for you if:

  • You'd like to be able to eat whenever you want
  • You need complex tooth movement
  • You're looking for the very cheapest treatment option

The best way to know about the price and duration of your Invisalign treatment is to visit an Invisalign provider near you for an assessment.

They will be happy to give you all the information you need to decide between braces or Invisalign.


Are braces or Invisalign cheaper?

This depends on the duration and complexity of your tooth movement. Metal braces are generally the cheapest option, but Invisalign prices are often comparable. The best way to know for sure is to book a consultation.

Are braces faster than Invisalign?

No, not necessarily. In fact, in many cases Invisalign is faster than braces. Invisalign treatment can be as short as 3 months, and the average duration is 6-12 months.

We recommend you visit a nearby dentist who provides both options so you can get a personalised treatment plan.

Is Invisalign more comfortable than braces?

It's well known that fixed brace brackets can irritate the gums and cause mouth sores. Clear aligners have a smooth surface which eliminates this problem, making them more comfortable to wear.

Occasionally, patients experience discomfort from one of the edges of their aligners. If this occurs, you can mention it to your dentist or simply use a nail file to smooth the part in question.
