What are clear aligners? Everything you need to know before starting treatment
More adults and teens than ever before are looking for ways to straighten their teeth discreetly and comfortably. If you’re one of them, you may have already started searching terms like what are clear aligners, or looking at clear aligners before and after photos.
At Spa Dental Clinic, we’ve helped hundreds of patients improve their smiles using modern, evidence-based orthodontic solutions — including Invisalign clear aligners. In this blog, we’ll explain how clear aligners work, their benefits, cost, and what to expect before, during and after treatment.
Whether you’re comparing treatment options or thinking about at home clear aligners, this guide will give you the clear facts you need.
What are clear aligners?
Clear aligners are a modern alternative to traditional metal braces. They are made from smooth, transparent plastic and are custom-designed to fit snugly over your teeth. The aligners gradually shift your teeth into a straighter position using controlled pressure.
They are removable, nearly invisible, and designed for comfort — which is why they’re a popular choice for adults and teens who want to straighten their teeth discreetly.
Unlike fixed braces, clear aligners don’t use wires or brackets. Instead, you’ll receive a series of aligners, each one slightly different, which you wear for around two weeks before switching to the next set.
At Spa Dental Clinic, we offer Invisalign — the most recognised and trusted clear aligner system worldwide. You can also explore more about the system at the official Invisalign UK website.
Clear aligners before and after: what results can you expect?
If you’re wondering about clear aligners before and after, it’s worth knowing that aligners can treat a wide range of orthodontic issues:
✅ Crowded teeth
✅ Gaps between teeth
✅ Overbites and underbites
✅ Crossbites
✅ Minor rotations
Results will vary depending on the severity of your case, but most patients start to see visible improvements within a few months. For many, treatment is completed in 6 to 18 months.
We provide digital scans at your consultation so you can preview your expected outcome — a helpful tool for visualising your clear aligners teeth results before committing.

At home clear aligners vs. in-clinic treatment
In recent years, at home clear aligners have grown in popularity. These treatments are usually marketed as a cheaper, more convenient alternative to in-practice aligner systems. While the idea of straightening your teeth without leaving home may sound appealing, there are some important differences to be aware of.
Clear Aligners Comparison
| Feature | At-Home Aligners | In-Clinic Invisalign Treatment |
|---|---|---|
| Supervision | Remote or minimal | Regular dental monitoring |
| Customisation | Limited | Fully bespoke using 3D scans |
| Risk Level | Higher due to lack of in-person checks | Lower due to dentist-led planning |
| Suitability Check | Usually online | Clinical oral health assessment in person |
| Results Guarantee | Not always included | Most practices offer refinements if needed |
At Spa Dental Clinic, we believe that smile transformations should be safe, monitored, and predictable. That’s why all Invisalign treatment is guided by experienced dentists with regular reviews throughout the process.

Clear aligners cost: what should you expect?
One of the first questions patients ask is: how much do clear aligners cost? It’s a fair question — and the answer depends on several factors:
✅ The complexity of your case
✅ Length of treatment
✅ Number of aligners required
✅ Whether refinement aligners are needed
✅ Retainers post-treatment
At Spa Dental Clinic, our Invisalign packages typically start from £1,995 for a single arch, and we offer flexible monthly payment plans to spread the cost. Every treatment is personalised, so you’ll receive a full quote after your consultation.

We always aim to be transparent and supportive when it comes to clear aligners cost, helping you make a choice that fits your budget and your smile goals.
Are clear aligners right for you?
Clear aligners are suitable for most adults and teens with mild to moderate alignment issues. They may not be ideal for very complex orthodontic cases, or for patients who struggle to wear them consistently.
Aligners must be worn 20–22 hours per day and only removed for eating, drinking (except water), and brushing. Commitment to the treatment is key for success.
We offer thorough consultations to assess whether you’re a good candidate. Our digital scanning system means no messy impressions — just fast, accurate results.
