If you have been searching for Invisalign near West Wickham, you are probably weighing up whether clear aligners could straighten your teeth without the look, or the lifestyle disruption, of fixed braces. It is a common question, and a fair one. Crooked, crowded or gapped teeth affect confidence far more than most people admit, yet the idea of a mouth full of metal for two years puts many adults off ever asking about treatment.
At Beckenham Smiles Dental, on the High Street in Beckenham, we see patients from West Wickham, Elmers End, Eden Park and the surrounding areas who want a straighter smile but need it to fit around work, family life and social commitments. This guide walks through exactly how Invisalign works, who it tends to suit, what treatment actually feels like day to day, and what it costs, so you can decide whether it is worth booking a consultation.
What is Invisalign®?
Invisalign is a system of clear, removable aligners used to gradually move teeth into a straighter position, and is one of the treatments offered as part of our wider cosmetic dentistry services. Rather than using fixed brackets and wires, the treatment relies on a series of custom made trays, each one slightly different from the last, that apply gentle, controlled pressure to specific teeth.
It is one of several brands of clear aligner on the market, but it is the most established and widely recognised, with a long clinical track record. The aligners are made from a smooth, transparent thermoplastic material, which is why many patients describe them as “invisible braces”. They are barely noticeable when worn, which is a large part of their appeal for adults who want discreet teeth straightening near West Wickham without it being obvious to colleagues or clients.
How do Invisalign® clear aligners work?
Each aligner is designed to move your teeth by a small, precise amount, usually around a fraction of a millimetre. Over the course of treatment, you progress through a series of these trays, each continuing the movement from where the last one left off.
The process is planned digitally from the outset. Your dentist takes digital scans or impressions of your teeth, which are used to build a 3D treatment plan showing how your teeth are expected to move from their starting position to the intended final result. This plan is broken down into stages, with each stage represented by a different aligner.
In broad terms, the process looks like this:
- Digital scan or impressions taken of your teeth and bite.
- A digital treatment plan is created, mapping out each stage of movement.
- Custom aligners are manufactured based on that plan.
- You wear each aligner for a set period before moving on to the next.
- Progress is monitored at review appointments throughout treatment.
Because the movements are mapped out from the beginning, most patients can see a simulation of their projected result before treatment starts, which many find reassuring.
Who may be suitable for Invisalign®?
Clear aligners work well for a wide range of adults and teenagers, particularly those dealing with:
- Mild to moderate crowding
- Gaps or spacing between teeth
- Minor to moderate bite irregularities
- Teeth that have shifted slightly with age
- Relapse after previous orthodontic treatment
Invisalign tends to suit patients who want a treatment option that is removable, discreet and relatively low profile in daily life. It is often a good fit for working adults, and for anyone who has avoided straightening their teeth in the past because they did not want visible metal braces. For younger patients, our children’s dentistry team can advise separately on whether early intervention is appropriate.
What dental concerns can clear aligners help address?
Beyond general crowding and spacing, clear aligners are commonly used to help with:
- Overcrowded teeth that are difficult to clean properly
- Noticeable gaps, including a gap between the front teeth
- Mild overbite, underbite or crossbite
- Teeth that have drifted following tooth loss or gum changes
- Cosmetic concerns where teeth position affects the overall appearance of a smile, sometimes addressed alongside a full smile makeover
Addressing crowding can also make it easier to clean between teeth effectively, which may support better gum health over time, an area covered in more detail on our periodontics page. That said, every case is different, and the right approach depends on your individual bite and dental history, which is why a proper assessment matters.
Who is not suitable for Invisalign®?
Clear aligners are not the right fit for every case. More complex bite problems, significant jaw discrepancies, or certain types of severe crowding may respond better to traditional braces or, in some cases, a combination of orthodontic approaches available through our specialist dentistry team. Patients who struggle to commit to wearing removable aligners for the recommended hours each day may also find results are compromised. Your dentist will be honest with you if Invisalign is unlikely to give you the outcome you are hoping for.
What happens during the initial consultation?
Your first appointment is really about finding out whether Invisalign is a realistic option for your teeth, and what result you might reasonably expect.
Dental assessment and treatment planning
During this visit, your dentist will typically:
- Examine your teeth, gums and bite
- Take digital scans, photographs or X-rays where needed
- Discuss what is bothering you about your current smile
- Explain whether Invisalign is likely to be suitable, or whether another approach may serve you better
- Talk through the expected timeline, number of aligners and approximate cost
This is also the point where any underlying issues, such as untreated decay or gum disease, would need to be addressed before orthodontic treatment begins. Straightening teeth over an unstable dental foundation is not advisable, so your dentist may recommend preventive care or restorative work, such as white fillings, first if required.
How long does Invisalign® treatment take?
Treatment length varies considerably depending on how much movement is needed. Mild cases might be completed in a few months, while more involved cases can take a year or longer. As a general guide, many adult cases fall somewhere between six and eighteen months, though this is not a fixed rule and your dentist will give you a personalised estimate once your treatment plan has been mapped out.
How often should you wear clear aligners?
For treatment to progress as planned, aligners generally need to be worn for around 20 to 22 hours a day, removed only for eating, drinking anything other than water, and cleaning your teeth. Consistency matters more than almost anything else in clear aligner treatment. Wearing them inconsistently, or leaving them out for extended periods, can slow progress or affect the final result.
What is it like wearing Invisalign® day to day?
Most patients adjust to wearing aligners within the first week or two. It is common to notice mild pressure or tightness for a day or so after switching to a new tray in the series, which is a sign the aligner is doing its job. This sensation usually settles quickly.
Speech may feel slightly different for the first few days, with some patients noticing a mild lisp, though this typically resolves as the tongue adapts. Because the aligners are removable, you retain a good degree of normal daily function, which is one of the main reasons patients choose this route over fixed braces.
Can you eat and drink normally with clear aligners?
Yes, largely. Because aligners are removed before eating, there are far fewer food restrictions than with fixed braces. You can eat what you like, as long as you take the aligners out first. The main habit to build is remembering to remove them before meals and snacks, and to clean your teeth before putting them back in, so food debris is not trapped against your teeth for hours at a time.
Drinking water with aligners in is fine. Hot drinks, sugary drinks and anything other than water are best consumed with the aligners out, both to protect the plastic from warping and to reduce the risk of decay from sugar sitting against your teeth. Regular scale and polish visits alongside treatment can help keep this in check.
How to clean your teeth and aligners
Good oral hygiene becomes even more important during clear aligner treatment, since the aligners sit closely against the teeth for most of the day.
- Brush and floss your teeth before reinserting your aligners after eating
- Rinse aligners with lukewarm water each time you remove them
- Clean aligners gently with a soft brush, avoiding hot water which can distort the plastic
- Avoid coloured or scented soaps and toothpaste, which can stain or damage the trays
- Store aligners in their case when not being worn, rather than in a napkin or pocket
What happens if you don’t wear your aligners as instructed?
Missing the recommended wear time, even occasionally, can slow your teeth’s progress or mean a tray no longer fits as intended once you return to it. If aligners are left out for an extended period, teeth can begin to shift back slightly, sometimes requiring your dentist to take new scans or adjust the plan. If you are struggling to stick to the wear schedule, it is always better to flag this at your next review rather than push on and hope it resolves itself.
What happens after active treatment?
Once your teeth have reached their planned position, active treatment is complete. However, this is not quite the end of the process.
Why are retainers important?
Teeth have a natural tendency to drift back towards their original position over time, a process known as relapse. Retainers, whether fixed, removable, or a combination of both, are used to hold your teeth in their new position while the surrounding bone and gum tissue stabilises, and are sometimes provided as part of our prosthetics service. Skipping retainer wear is one of the most common reasons patients see their teeth shift after previously investing in straightening treatment, so this stage should never be treated as optional.
Invisalign® vs traditional braces
Both approaches can achieve excellent results for the right case. The table below summarises the main practical differences patients tend to ask about.
| Feature | Invisalign® / Clear Aligners | Traditional Fixed Braces |
|---|---|---|
| Visibility | Low, aligners are clear | Visible metal or ceramic brackets |
| Removable | Yes, for eating and cleaning | No, fixed in place |
| Food restrictions | Minimal, aligners removed to eat | Some foods best avoided |
| Cleaning | Straightforward, brush and floss as normal | Requires extra care around brackets |
| Suitability | Mild to moderate cases | Mild to complex cases |
| Comfort | Smooth plastic, mild pressure per tray | Possible irritation from brackets and wires |
| Patient responsibility | High, requires discipline with wear time | Lower, fixed in place throughout |
Your dentist can advise which route is more appropriate once they have assessed your teeth and bite.
How much does Invisalign®/clear aligner treatment cost?
Clear aligner treatment at Beckenham Smiles Dental starts from £1,850. The exact cost depends on the complexity of your case and the number of aligners required, which your dentist will confirm once your treatment plan has been finalised at consultation. For full pricing details across our treatments, our fee guide is available to review, and 0% APR finance is available through Tabeo for patients who would prefer to spread the cost. Patients looking to budget for ongoing care may also wish to look at our patient plan options.
Common mistakes to avoid with clear aligners
A few habits tend to cause the most problems during treatment:
- Not wearing aligners for the recommended hours each day
- Losing or damaging trays and delaying replacement
- Skipping review appointments
- Neglecting retainer wear once active treatment finishes
- Eating or drinking anything other than water with aligners in
Avoiding these simple pitfalls makes a noticeable difference to how smoothly treatment progresses.
Professional advice before starting treatment
Every mouth is different, and what works well for one patient may not be the right plan for another. Rather than relying on online guides or comparing your case to someone else’s experience, the most reliable next step is a proper assessment with a dentist who can examine your teeth, discuss your goals honestly, and confirm whether Invisalign is a suitable option for you.
