A beautiful smile is a powerful thing. It can change your outlook, help you overcome inhibitions and give you greater confidence – in both your professional life and when you are out socialising.
With Invisalign, you can achieve this smile without using traditional fixed braces. This Fact Sheet provides information about the Invisalign System, so you can discover if a clear, convenient and comfortable teeth straightening treatment is the right course of action for you.
If you’ve ever thought about improving your smile, Invisalign could be the clear way forward.
Developed by Align Technology together with leading orthodontists in 1997, Invisalign straightens your teeth using a series of custom-made clear aligners.
Invisalign is an advanced clear aligner system designed to straighten your teeth discreetly and comfortably. Instead of using traditional metal braces, Invisalign uses a series of custom-made, removable aligners that gently guide your teeth into better alignment over time, helping you achieve a straighter smile without the inconvenience of fixed brackets or wires.
Each aligner is made from SmartTrack material, which fits snugly over your upper and lower teeth to provide controlled, consistent movement. This makes it an ideal option for correcting a wide range of issues, including:
Misaligned or crowded upper teeth
Gaps between teeth
Bite problems (such as overbites or crossbites)
Relapse after previous orthodontic treatment
Because the aligners are removable, you can maintain your daily oral hygiene routine with ease, and even pair your treatment with teeth whitening for a brighter, more confident result.
Whether you’re looking to straighten your upper teeth, lower teeth, or both, Invisalign offers a flexible and nearly invisible way to transform your smile. At our Southampton dental practice, we combine the latest digital scanning technology with personalised care to deliver outstanding results using this cutting-edge system.
It takes approximately between 9 and 18 months to create a new smile using Invisalign. Getting there takes just four simple steps:
By using advanced technology, Invisalign can treat a broad range of dental and orthodontic issues that were previously treated with traditional braces – from minor tooth movements to more complex cases. These issues include:
Custom-made to fit your teeth and your lifestyle, Invisalign offers many benefits beyond your brand-new smile:
Treatment length varies depending on your case. Some patients see results for their straighter teeth in as little as 4–6 months, while more complex cases can take 12–18 months.
During your consultation, we’ll give you a realistic timeframe based on your smile goals.
Invisalign isn’t painful, but you may feel mild pressure or tightness when you switch to a new aligner, this is a sign that the aligners are working. The sensation usually fades after a day or two.
You should remove your aligners before eating or drinking anything other than water. Eating with them can damage the plastic and lead to staining. The good news?
There are no food restrictions, as there are with fixed braces.
For the best results, you should wear your aligners for 20–22 hours per day.
Only remove them to eat, drink, brush, and floss. Consistent wear is key to keeping your treatment on track.
If you misplace an aligner, contact us as soon as possible. Depending on your progress, we may advise you to move to the next aligner, wear the previous one temporarily, or order a replacement.
Clean your aligners twice a day using a soft toothbrush and lukewarm water (never hot). You can also use cleaning crystals or specialised solutions to keep them clear and odour-free. Avoid using toothpaste, as it can scratch the surface.
Invisalign can treat a wide range of alignment problems, including crowded teeth, gaps, overbites, underbites, and crossbites.
However, very complex cases may still require fixed braces. We’ll assess your suitability during your initial consultation.
The cost of Invisalign depends on the complexity of your case and the length of treatment.

EXCELLENT Based on 82 reviews Posted on Anita Hair2026-02-26Trustindex verifies that the original source of the review is Google. I’ve had an excellent experience with Costin and Pam at Portland Street Dentist. I decided to get braces just before turning 30, and it’s honestly one of the best decisions I’ve ever made. My teeth are now so straight, and I couldn’t be happier with the results. I was quite nervous at the start and told Costin that I really don’t like dentists or pain, but every single appointment was handled with such care and gentleness. They always made me feel comfortable and reassured throughout the whole process. I would absolutely recommend Portland Street Dentist to anyone considering braces especially if you’re feeling a little anxious like I was! I have also had other dental treatment here, and has been great service every time.Posted on Lewis Ball2026-02-05Trustindex verifies that the original source of the review is Google. I honestly can’t recommend this dentist highly enough! I had Spark orthodontic treatment and the results are absolutely fantastic. My face aches from smiling so much! 😁 Pam and Costin have been incredibly welcoming from the start and the level of care they provide is exceptional. They made every appointment comfortable, reassuring, and kept me informed throughout. I now wouldn’t want to go anywhere else! Thank you both again for such brilliant results!Posted on Jade Mori2025-08-22Trustindex verifies that the original source of the review is Google. Pamela and Costin made me feel welcome and relaxed throughout the process of my dental work. All of my options were explained with pros and cons, and they went the extra mile to ensure that I would leave happy with my new smile (which I really did!). Costin is a perfectionist!Posted on Καλλιόπη Κασάπογλου2025-07-02Trustindex verifies that the original source of the review is Google.

As a nervous patient, Pamela and Costin made me feel at ease from the very beginning. I had a root canal filling, two smaller fillings and a clean. I can honestly say that it's been the best dental experience I've ever had.

Great experience, very personal, welcoming, caring and calming. Highly recommend.Posted on Corina Vasile2024-12-18Trustindex verifies that the original source of the review is Google. My experience with the practice and both Costin and Pamela was absolutely great because I felt safe, really looked after, treated with respect and kindness at all times. This is that type of place where you feel you are at the centre of their efforts and the price is a fair one compared to so many other places. Pamela and Costin worked with me for aprox 3 years now. I first had a crown made and then braces and the result of both is just amazing. Nothing was too much for them and they went beyond and above with their care and assistance so I can enjoy smiling again. Thank you both for a really meaningful experience with an outstanding result😘Posted on Nvk K.n.v2024-10-21Trustindex verifies that the original source of the review is Google.
