Invisalign® Express
- Invisalign Express is our quickest treatment option, ideal for very minor orthodontic corrections. The treatment includes up to seven aligners and can usually be completed in as little as six months.
Invisalign® clear aligners
The convenience and comfort of Invisalign clear aligners have made them a popular choice for many people worldwide who are looking to straighten their teeth and help improve their smile.
Why choose Invisalign clear aligners?
Traditional fixed braces are made up of metal, plastic or ceramic brackets which are attached to each of your teeth and joined by a wire. Whilst fixed braces are effective, many people don't like the look or feel of them. Invisalign clear aligners won't compromise your appearance during treatment, as they're almost invisible and can be removed for eating and cleaning your teeth.

Ana Júlia Asanuma
My experience with aligners at Portman Smile Clinic was great from start to finish. The treatment was much faster than I expected and the final result is perfect. I barely felt any pain at all, which really surprised me, as the aligners are very gentle and comfortable. The orthodontists were excellent and always made me feel at ease. The nurses were so kind and supportive, and the reception team was always friendly and helpful. You can really tell that the clinic is very well managed and that they care about their patients. I’m really happy with my smile now and I would 100% recommend Portman Smile Clinic to anyone looking for a smooth and positive orthodontic experience.
Ana Clara Asanuma
I had my aligner treatment at Portman Smile Clinic and I honestly couldn’t be happier with the result. The treatment was really quick and my tooth looks absolutely perfect now. I was a bit nervous at the beginning, but it was almost painless — the aligners were very comfortable and easy to get used to. All the orthodontists were amazing, very kind and professional, and they always explained everything clearly, which made me feel relaxed and confident. The whole team was lovely, from the reception staff to the nurses and management. Everyone was friendly, organised and welcoming every time I visited. I’m so happy I chose Portman Smile Clinic and I would definitely recommend it to anyone thinking about aligners, especially teenagers like me!
