Are you looking for some Invisalign before and after pictures before committing to your orthodontic treatment? Well, you've come to the right place.

Clear aligners like Invisalign are becoming more and more popular in the UK, especially among adults and teens. They provide an effective yet discreet way to straighten teeth, and they work for around 90% of people. We understand it's a big decision though, especially as the price of Invisalign makes it a significant investment.

So, if you're leaning towards this treatment but want to see some other people's Invisalign results first, keep reading. Here we feature cases from four patients with different alignment problems, as well as some time-lapse videos showing Invisalign before and after transformations.

Invisalign costs not in your budget? Here's what we recommend…

Many people experience good results with Invisalign. You can find before after pictures from real patients below in this article.

But since Invisalign costs up to £5.500 for complex treatments, you might be looking for a more affordable alternative?

We recommend SmileWhite Aligners. They can treat complex cases, like Invisalign. But they are up to 40% cheaper. In addition, you'll get free retainers and whitening to complete your dazzling smile.

Invisalign before and after: Gaps and Underbite

What will your teeth look like after Invisalign?

This 23-year-old male patient had an underbite malocclusion, meaning his upper teeth sat behind his lower teeth. He also had noticeable gaps between several of his teeth (diastema). But if you saw his teeth after Invisalign treatment, you would never guess what they looked like before.



This was quite a severe Invisalign case and took 24 months to correct, involving 55 aligners for the upper teeth and 60 for the lower.

As you can see from these pictures of teeth gaps before and after Invisalign, the aesthetics of the smile were much improved. Closing gaps in teeth can also make them easier to clean, since it reduces the chances of bits of food getting trapped between them.

Invisalign before and after: Overcrowding

The next case was much more straightforward to treat, taking just 12 months and using 32 upper trays and 33 lower. The patient required a small amount of IPR (interproximal reduction), which involves the dentist filing down the tooth enamel in certain places. This creates more space for the teeth to fit into alignment better.



Looking at the before and after photos, the overcrowding is not immediately obvious from the front view. However, the open mouth view shows more clearly how several of the teeth were out of alignment, and you can also see this from the side.

If you are conscious of how your teeth look, even if all your friends think they are fine, Invisalign aligners could be a great solution. Having metal braces fitted might feel a little extreme to you, but clear aligners let you straighten your teeth much more subtly.

If you only need slight tooth movement, you might be a good candidate for Invisalign Lite, a treatment designed for milder cases. You may also want to consider direct-to-consumer aligners, also know as at-home aligners, which don't require regular visits to a dentist. Instead, you check in online and your dentist tracks your progress via an app.

NewSmile is a Canadian company that brought its clear aligners to the UK market in 2022. NewSmile aligners are made from the clearest material and the company offers excellent service at the best price.

They don't have any physical locations, so you'll need to purchase an aligner kit to get started. One of their Impression Specialists will guide you through the process on a video call when you're ready.

NewSmile aligners are very affordable, costing just £1,395 (currently discounted to £1,295). But even better, this price includes whitening foam to use in your aligners, plus your first set of retainers!

Choose their daytime package for treatment in 4-6 months, or nighttime aligners for a more discreet treatment that takes 8-10 months. Both options come with 0% interest payment plans available.

Invisalign open bite treatment results

In this next case, the patient had a significant open bite as well as a posterior crossbite. In plain terms, this means:

  • There is a gap between the top and bottom front teeth when biting
  • The top teeth at the back sit inside the bottom teeth, when they should be outside
  • The upper arch is quite narrow

Having an overbite can lead to problems with eating and speech, as well as poor facial aesthetics. But it's reassuring to know that cases like this don't always require traditional braces.



Despite the amount of correction needed, this case took just 13 months to treat, using 27 sets of aligners. The patient needed Invisalign attachments and had to wear elastics with his aligners throughout the treatment to aid tooth movement. The elastics hook onto the top and bottom aligners to encourage greater tooth movement. They're usually attached to molar teeth so are not too visible.

Although this patient's treatment was successful, some cases of overbite which require vertical tooth movement may not be treatable with the Invisalign system. Instead, clear fixed braces are a good alternative to metal braces for patients who want a less noticeable treatment.

Overbite before and after Invisalign

At the opposite extreme to an open bite, an overbite (or deep bite) means the upper front teeth sit too far down in relation to the lower teeth. Look at this patient's before and after pictures, and you'll see that her bottom teeth were hardly visible when she smiled. She also had some quite significant crowding.



This treatment took 18 months, which is about the average time for Invisalign. It's also worth noting that this patient was 49 years old when she began her treatment, so it's really never too late to get your teeth straightened if you're unhappy with how they look.

Invisalign results time lapse video

This patient, who had treatment with Invisalign Comprehensive for overcrowding, has published a fascinating Invisalign time lapse video documenting his treatment. The video shows the front view first, then the view from the top. You can see that there was significant movement to one of his premolar teeth which was positioned too far into his mouth.

This is one of the benefits of choosing Invisalign over some other clear aligner brands; Invisalign have been operating for the longest and have been developing their technology for over 20 years, meaning they can perform more complex tooth movement and treat up to 90% of cases.

Not had enough of looking in other people's mouths yet?

We have one more video for you, from an Invisalign Elite provider in Canada. These before and after images show that the Invisalign system can be effective in even some of the worst cases of crowding, diastema and crossbite.


Not only are Invisalign aligners comfortable and discreet, but these aligners are also effective on 90% of orthodontic cases – even some of the most severe and extreme – as these before and after pictures have shown. Invisalign treatment results show a noticeable improvement in smile aesthetics, as well as in bite function.

If you're still undecided, why not read some Invisalign reviews which we have compiled? These give a better idea of what it's actually like to wear clear aligners.

Invisalign isn't the only option…

There are more affordable aligner brands like Smile White, which can achieve the same before-after results in most cases.
