What is Invisalign and how does it work?
Invisalign is a modern orthodontic system that uses a series of clear, removable aligners to gradually straighten your teeth. Each aligner is custom-made from advanced, medical-grade plastic using 3D digital scans of your mouth.
The treatment works through small, controlled tooth movements. Every one to two weeks, you change to the next set of aligners in the series, each slightly different from the last, guiding your teeth closer to their ideal position.
At Horley & Gatwick Dental Centre, every Invisalign journey starts with a digital intraoral scan and a 3D simulation of your future smile — so you can visualise the results before beginning treatment.
Why patients love Invisalign:
- Discreet, transparent design.
- Comfortable and metal-free.
- Removable for eating, brushing, and special occasions.
- Suitable for adults, teens, and in some cases, younger patients.

What dental issues can Invisalign correct?
Many people associate Invisalign only with mild alignment issues, but the truth is it can correct a wide range of orthodontic concerns. Modern aligner technology can now treat:
- Crowded teeth – where teeth overlap or twist.
- Spacing issues – gaps or diastemas between teeth.
- Overbites and underbites – where upper or lower teeth extend too far.
- Crossbites – when some upper teeth sit inside the lower teeth.
- Open bites – when upper and lower teeth don’t meet properly.
Our experienced orthodontist, Dr Ilias Marinopoulos, is recognised as one of Europe’s leading Invisalign providers and can manage both simple and complex cases successfully. Patients in Horley and Crawley trust his expertise to achieve functional, long-lasting, and aesthetic results.

What are the advantages of Invisalign?
The benefits of Invisalign go far beyond its clear, discreet appearance. Patients appreciate the combination of comfort, convenience, and predictability it offers.
Key advantages include:
- Comfort: Smooth aligners without wires or brackets reduce irritation.
- Aesthetics: Virtually invisible — ideal for professionals and teens.
- Removability: Eat, brush, and floss as usual.
- Hygiene: Easier to maintain oral health throughout treatment.
- Predictable outcomes: Digital planning allows precise tooth movement.
- Fewer visits: Appointments are typically shorter and less frequent.
At Horley & Gatwick Dental Centre, we also include teeth whitening and extra aligners if needed, offering added value and peace of mind throughout your Invisalign experience.

How long does Invisalign treatment take?
The duration of Invisalign treatment depends on the complexity of the case and how consistently the aligners are worn. Most treatments last between 6 and 18 months.
Patients wear their aligners for 20–22 hours per day, changing them every one to two weeks. The more precisely you follow this routine, the faster and more predictable your results will be.
Thanks to digital smile design, our dentists in Horley and Crawley can give you a realistic timeline before treatment begins, showing your expected progress and outcome. Some minor corrections may take as little as six months, while comprehensive smile transformations may take longer — but with visible improvements along the way.

Can Invisalign fix an overbite or complex case?
Yes. Modern Invisalign technology is highly versatile and can correct many complex orthodontic issues once reserved for traditional braces. Using attachments (small tooth-coloured elements) and precision mapping, Invisalign applies targeted pressure to guide teeth into the correct position.
At our Horley and Crawley practice, even challenging bite problems such as overbite, crossbite, and open bite can often be treated successfully. Our orthodontic specialist uses advanced digital planning to ensure that every stage of movement is safe and predictable.
For severe cases, Invisalign can be combined with minor cosmetic or restorative procedures to optimise both function and aesthetics.

After Invisalign treatment, it’s important to maintain your results with retainers. These are custom-made devices that keep your teeth in their new positions while the surrounding bone stabilises.
We provide both fixed and removable retainer options, depending on your lifestyle and preferences. Regular check-ups and professional cleanings ensure your new smile stays healthy and bright.
Patients in Horley and Crawley also receive guidance on oral hygiene, diet, and whitening maintenance. With proper care, your Invisalign results can last a lifetime — keeping your smile straight, confident, and naturally beautiful.
