Teeth Straightening London: Aligners, Braces & Timelines
Once you decide to straighten your teeth, the next step is choosing between clear aligners and braces, and finding the right clinic to plan your treatment.
Teeth straightening usually means one of four options: clear aligners, ceramic braces, lingual braces hidden behind the teeth, or fixed metal braces.
This guide explains which cases each option suits, how long treatment takes, and what happens at your first appointment.
Teeth Straightening in London: Your Treatment Options Compared
The four options differ in how visible they are and in how much control the dentist has. What you pay depends on how much movement is needed and which system is used. Our guide to how much Invisalign costs sets out the figures in full.
| System | How it works | How visible |
|---|---|---|
| Clear aligners | Removable trays | Barely noticeable |
| Ceramic braces | Tooth-coloured brackets | A faint outline |
| Lingual braces | Brackets behind the teeth | Not visible |
| Fixed metal braces | Metal brackets and wire | Visible |
What Each System Is Best At
Aligners suit mild to moderate crowding, gaps, and teeth that have drifted since earlier braces. Fixed braces work better where teeth need turning, straightening up or moving root and all, because each bracket is fixed to its tooth and the wire guides it, rather than a tray pushing against it.
Invisible Braces London: The Discreet Options Explained
Invisible braces come in three forms: two that are hard to notice, and one nobody sees. Clear aligners are transparent and removable, ceramic brackets show as a faint outline, and lingual braces sit behind the teeth, out of sight.
Removable and clear. Aligners are the easiest to live with, because you can take them out to eat and clean your teeth. We offer both Invisalign and Smartee aligners. Our guide to Invisalign in London explains what the treatment involves, step by step.
Fixed and hidden. Lingual braces give the control of fixed braces without being seen.
Expert Tip: Your speech may feel different for a week or two after lingual braces are fitted, while your tongue gets used to them.
Are Lingual Braces Really Invisible?
From the front, yes. The brackets are bonded to the tongue side of the teeth, so nothing shows when you smile or talk. That makes them the only fully hidden option.
Clear Aligners or Fixed Braces: Which Is Right for You?
Personal preference plays a part, but what your teeth need usually matters more. A systematic review in BMC Oral Health found aligners can fall short of fixed appliances on fine detail. The difference shows in tooth torque (the angle of the root) and in how the teeth finally meet. Three things usually settle the choice:
- How much the teeth need to move. Teeth that need turning a long way are better suited to fixed braces.
- How consistently you can wear aligners. They only move teeth while they are in.
- What the bite needs. Fine detail in how the teeth meet is easier to finish with a wire.
Our comparison of Invisalign and fixed braces sets the two side by side.
When Fixed Braces Are the Better Choice
Where teeth are severely crowded or badly rotated, a fixed appliance is more predictable. A Cureus review of severe cases found aligner results harder to guarantee, because they depend on wear. A fixed appliance does not depend on wear in the same way, and can finish some cases faster.
How Long Does Teeth Straightening Take?
Adult cases usually run between six months and two years. The Oral Health Foundation puts the usual range at several months to around two and a half years. As a guide, treatment falls into three broad groups:
- Minor front-tooth alignment. Three to six months.
- Moderate crowding or spacing. Six to twelve months.
- Complex bite correction. Twelve months to two years.
Our guide to clear aligners in the UK covers what happens between visits.
Helpful Tip: Wearing your aligners for around twenty hours a day is the most useful thing you can do to keep treatment on time.
What Makes Treatment Take Longer
- Teeth that need moving root and all, rather than just tilting
- Aligners worn for less than the twenty hours a day advised
- Extractions or gum treatment needed first
What Happens at Your First Appointment?
At your first appointment, we will examine your teeth and draw up a plan; the appliance itself comes later. The visit will usually include:
- Full examination and x-rays. These show the roots, the bone, and anything needing treatment first.
- Photographs and scans. These record the starting position and plan the movement.
- Options and timings. Which systems suit your case, and how long each would take.
- A digital preview where aligners are suitable. Invisalign treatment is planned on screen before any tray is made.
Retainers: Keeping Your Teeth Straight for Good
Once treatment ends, teeth need help to stay where they have been moved. The British Orthodontic Society is clear that teeth drift back towards their original positions once an appliance comes off. Almost every case needs a retainer.
Fixed retainers. A thin wire is bonded behind the front teeth, where it holds them in place and cannot be seen.
Removable retainers. Clear trays worn every night for the first year, then less often.
Expert Tip: Think of your retainer as a lasting habit rather than a final stage of treatment. The longer you wear it, the longer your teeth stay straight.
How Long Do You Wear a Retainer?
Wearing a retainer becomes part of your routine rather than a treatment with an end date. Retainers are usually worn every night for the first year, then on alternate nights, because teeth naturally drift back without one.

Short answers on teeth straightening: timings, age, aligners or braces, comfort and what happens once the appliance comes off.
Teeth Straightening London: What to Remember
Choosing between the options is easier once you know how they differ. How visible you want the appliance to be narrows the choice, and what your bite needs settles it.
The short version:
- Four options: clear aligners, ceramic, lingual and fixed metal braces
- The hidden one: lingual braces are the only fully hidden option
- Typical timeline: six months to two years
- What decides the choice: how much movement the case needs
- What keeps teeth straight: retainers, worn every night at first and then less often
An assessment turns these points into a plan for your teeth, showing which teeth need to move and how far. The timing, the choice of appliance and the retainer afterwards are all based on it.
