Procedure guide · Dentistry (orthodontics)
Clear aligners are removable orthodontic appliances that move teeth gradually. An NHS orthodontic department describes them as a removable brace that looks more discreet than metal brackets. Unlike a single dental procedure they are a course of treatment with regular reviews. So the key question for a visitor is how the orthodontist will monitor progress once you are home.
What are clear aligners?
Orthodontics is the branch of dentistry that repositions teeth. Harrogate and District NHS Foundation Trust explains that treatment aims to improve the bite and the appearance of the teeth and can sometimes help protect long-term tooth and gum health. It lists several appliance types: removable plates, functional appliances, fixed braces with brackets and wires, and aligners.
Aligners are thin, close-fitting trays that are taken out to eat and clean. The same trust notes that such aesthetic appliances are not generally available on the NHS. That is one reason adults look abroad for this treatment. Fixed braces work differently. The NHS describes brackets glued to each tooth with a wire that applies gentle pressure, adjusted at regular reviews.
Who may be suitable for aligners?
The NHS says people may need orthodontic treatment if their teeth are crowded or stick out, if the jaws do not meet properly, if there are large gaps or if tooth position makes eating or cleaning difficult. Whether aligners or fixed braces suit a particular bite is a clinical decision. An orthodontist may recommend fixed braces for some problems, or advise treating gum disease or decay first. Your orthodontist decides what is suitable.
Aligners also depend on you. They only work while they are in the mouth. Ask the orthodontist how many hours a day you will be asked to wear them and be honest about whether that fits your life.
What records does an orthodontist need first?
The Harrogate trust describes a full examination of the teeth with possible X-rays. If treatment is indicated, it takes moulds of the teeth and clinical photographs at a records appointment. A plan is then drawn up and discussed. Many clinics now use a digital scan in place of moulds. Before you travel you can usually share:
- Recent dental X-rays, including any full-mouth or jaw X-ray your dentist has taken
- Clear photographs of your smile and bite from the front and both sides
- A note from your dentist confirming your teeth and gums are healthy
- Details of any earlier orthodontic treatment and any retainers you still wear
- Information on crowns, implants or bridges, which can affect tooth movement
How do you plan treatment from abroad?
Aligner treatment usually unfolds over many reviews, so the plan must cover what happens between visits. Ask each clinic to describe its process in writing.
- Remote review of your photos and X-rays, then an in-person examination and scan in India
- Fitting of the first aligners and instruction on wear and cleaning
- Progress checks, which may be in person or by video depending on the clinic
- Refinement stage if teeth have not moved as planned
- Retention: retainers to hold the teeth in their new position
The NHS stresses that a retainer is needed afterwards to stop teeth moving back. The Harrogate trust recommends long-term retainer wear because teeth can keep moving after treatment ends. Agree with your own dentist that they will keep seeing you for routine check-ups throughout. Your dentist remains responsible for any decay or gum problems along the way.
What should you ask the clinic?
- Are aligners or fixed braces more appropriate for my bite and why?
- Who designs and reviews my treatment plan and are they a specialist orthodontist?
- How will progress be checked once I am home and what if an aligner does not fit?
- How many visits to India do you expect and at which stages?
- Are refinements and retainers included in the written estimate?
- Can my local dentist or orthodontist take over care if needed?

Questions people ask
Do I need to stay in India for the whole treatment?
Not usually, but it depends on the clinic’s process. Many plans involve an initial visit for examination and scanning, then progress checks that may be in person or remote. Ask the clinic to set out how many visits it expects and what it does if an aligner stops fitting while you are at home.
Will I need a retainer after aligners?
Yes. The NHS says a retainer is needed after orthodontic treatment to stop teeth moving back to their original position. An NHS orthodontic department recommends long-term retainer wear. Ask the clinic how retainers are provided and how you would replace one from home.
Are clear aligners the same as fixed braces?
No. Aligners are removable trays taken out to eat and clean. Fixed braces use brackets glued to the teeth with a connecting wire, as the NHS describes. Each suits different problems. The orthodontist decides which approach fits your teeth and bite.
