Quick answer
Clear aligners are removable and usually less noticeable, while fixed braces stay in place and may suit some complex cases better. Neither suits everyone. The right choice depends on your teeth, bite, daily habits and commitment, and it is decided after an examination at Bromley Smiles Dental.
Introduction
Few questions come up more often before teeth straightening than this one: aligners or braces? Both can move teeth, and both need planning, regular visits and retainers afterwards. Where they differ is in appearance, daily routine and the kinds of problems each can reach. This guide compares them plainly, including the situations where braces may be the stronger option, so you can arrive at a consultation in Bromley with sensible questions and realistic expectations.
What are clear aligners and fixed braces?
Clear aligners
Clear aligners are a series of thin, transparent trays shaped to your teeth. Each one moves the teeth a small step towards a planned position. You wear a tray for the time your dentist specifies, then switch to the next. Because the trays come out, you can eat, drink and clean your teeth as usual. Invisalign is a well-known system, and Bromley Smiles Dental offers it alongside other clear aligners.
Fixed braces
Fixed braces use small brackets bonded to the teeth, joined by a wire that is adjusted at set intervals. They cannot be taken out at home. Brackets come in several styles, including metal and tooth-coloured
A fair comparison
The table is a general guide only. How each point applies to you depends on your own teeth and bite.
| Factor | Clear aligners | Fixed braces |
| Visibility | Clear trays, usually less noticeable, though small attachments may be used | Brackets and wire are visible, though some styles are subtler than others |
| Removable | Yes, out for meals and cleaning | No, fixed throughout treatment |
| Hygiene | Brushing and flossing stay close to normal | Extra care needed around brackets and wires |
| Suitability | Often used for mild to moderate concerns and some more complex ones | May suit a wider range, including some complex bite problems |
| Discipline needed | High, as results depend on wearing trays as directed | Lower day to day, because the appliance stays on |
| Appointments | Regular reviews, with trays supplied in stages | Regular adjustment visits |
| Limitations | Some movements are harder to achieve | Food restrictions and a greater chance of mouth irritation |
No column wins outright. The sections below explain what sits behind each row.
How the two compare day to day
Appearance
Many adults and teenagers lean towards aligners because the trays are clear. They are not invisible, and some people notice a slight shine or a small change in speech for the first few days. Fixed braces are easier to spot, although tooth-coloured versions can be less obvious than metal. If looks matter a great deal to you, say so at your appointment.
Comfort
Both can leave teeth tender when movement begins or after a change of tray or an adjustment. Braces can rub the inside of the cheeks and lips. Aligners have no sharp parts, though edges can occasionally irritate. Your dentist can suggest ways to ease any discomfort.
Food and drink
With aligners, you remove the trays for anything other than plain water, then clean your teeth before putting them back. With fixed braces, very hard, sticky or chewy foods may need to be avoided because they can dislodge brackets or bend wires. Neither option is effortless. They simply ask for different habits.
Cleaning and gum health
Brushing and flossing are usually simpler with aligners, since nothing is attached to the teeth. With braces, plaque can collect around brackets if cleaning slips. Whichever you choose, regular preventive care visits help protect your gums and enamel while your teeth are moving.
Time and visits
How long treatment takes depends on your case more than on the appliance. A simple case may be quick with either, and a complex one may take longer with both. Your dentist can give an estimate after an examination, though it cannot be guaranteed.
How clear aligner treatment works
- Consultation and examination. Your dentist looks at your teeth, gums and bite and asks what you would like to change.
- Scans and records. Digital scans, X-rays or impressions help plan treatment accurately.
- Plan and quote. You see the proposed movement, the alternatives, the risks and a personal quote.
- Wearing the aligners. You wear each tray as directed and change on schedule.
- Reviews. Your dentist checks progress and adjusts the plan if needed.
- Retainers. When movement is complete, retainers help to hold the teeth in place.
Who may be suitable for each option
Aligners may suit you if
Your teeth and gums are healthy, your concern is one that aligners can reach, and you are comfortable wearing trays for most of the day. They are often considered for crowding, gaps and some bite concerns. For people thinking about how their smile looks, aligners can form part of wider cosmetic dentistry planning.
Braces may suit you if
Your bite problem is more complex, or you would find it hard to keep trays in for the hours required. Because braces cannot be taken out, they work continuously. For certain tooth movements, a clinician may find braces more predictable. In those cases, braces may be the better recommendation, and a responsible dentist will tell you so.
When something else comes first
Untreated decay or gum disease needs attention before teeth are moved. Treatment should start only when your mouth is healthy enough to support it.
Suitability is decided after an examination, so no article can say which route is right for your teeth.
Benefits and limitations
Clear aligners
Possible benefits: discreet trays, removable for meals and cleaning, and digital planning that shows the intended movement.
Limitations: results depend on wearing trays as directed, some movements are harder to achieve, and attachments or small reshaping may be needed. Trays can be lost or damaged.
Fixed braces
Possible benefits: they work around the clock without daily decisions and can suit a broad range of cases.
Limitations: they are more visible, harder to clean around, may involve food restrictions and can irritate the mouth. A broken bracket or wire may need an unplanned visit.
Risks common to both
All tooth movement carries risks. These can include tenderness, gum irritation, marks on enamel if cleaning is poor and, in a small number of cases, effects on tooth roots. Teeth may also drift back after treatment if retainers are not worn. Your dentist should explain these before you agree to start.
Retainers, aftercare and common mistakes
Retainers matter after both approaches. Teeth naturally tend to drift, and retainers help hold them where they have been moved. Your dentist will advise whether you need removable retainers, fixed ones or both, and for how long
Common mistakes include:
- Choosing an option because it seems easier, without checking it fits the problem.
- Wearing aligners for fewer hours than advised.
- Neglecting cleaning around braces or between trays.
- Skipping review or adjustment visits.
- Stopping retainer wear once the teeth look straight.
What about cost?
Costs vary between treatments and between cases, so a general comparison can mislead. At Bromley Smiles Dental, clear aligners start from £1,850. This is a “from” price, and a personal quote is given after assessment. Our fee guide has more detail. Finance is available through Tabeo at 0% APR, subject to status, with terms applying.

Frequently asked questions
Neither is better for everyone. Aligners are removable and less visible, while fixed braces may handle some complex cases more effectively. Your dentist will assess your teeth and bite and explain which approach may suit you.
Clear aligners are usually less noticeable because the trays are transparent, though small attachments may be used. Fixed braces are more visible, although tooth-coloured styles can be subtler than metal. Individual preferences vary.
Aligners can address many common concerns, but not every case. Some complex bite problems or tooth movements may be better suited to fixed braces. Suitability is decided after an examination of your teeth, gums and bite.
Both can cause tenderness when movement begins or after a new tray or adjustment. Braces may also rub on cheeks and lips. Discomfort varies from person to person, and your dentist can suggest ways to ease it.
Often, yes, because aligners come out for brushing and flossing. Fixed braces need more careful cleaning around brackets and wires. Whichever you choose, good home care and regular hygiene visits help protect your gums and teeth.
In most cases, yes. Teeth can drift back after treatment, and retainers help hold them in place. Your dentist will advise on the type, how long to wear them and how to look after them.
In some cases, yes, depending on age, teeth and how reliably the aligners would be worn. Your dentist will assess this at an examination and explain whether aligners or another approach may be more suitable.
Length depends on the case rather than the appliance. Simpler cases are usually shorter and complex ones take longer. Your dentist can give an estimate after examining you, though it cannot be guaranteed.
