Replacement Retainers in London

Retainers get lost in napkins, chewed by dogs, cracked in bags and worn thin by night-time grinding. Whatever happened to yours, the priority is the same: get a replacement before your teeth start to drift. We make replacement retainers for patients across London, whether your original treatment was with us, with another practice or abroad, and we keep your digital scan on file so future replacements are quicker.

What happens at a replacement retainer appointment?

1. Check: we look at your teeth, gums and old retainer, and check for any movement.
2. Scan: a 3D intraoral scan replaces messy impressions for most patients.
3. Choose: we discuss the right retainer type for you and give you a written price.
4. Fit: when the retainer is ready, we check the fit and explain how often to wear it.

If your teeth have moved, we will explain whether a new retainer can still be made now or whether a short corrective course is needed first.

What should you do if you have lost your retainer?

• Do not wait: teeth can move within days, especially in the first year after treatment.
• Wear an older retainer if you have one and it still fits, even if it is tight.
• Book a replacement and mention that the retainer is lost so we can prioritise.
• Avoid forcing a retainer that no longer goes in fully; ask us first.

What if your retainer is cracked or loose?

A small crack in a clear retainer may still hold the teeth for a short time, but cracked plastic can split further and rough edges can irritate the gums. A loose retainer is not holding the teeth properly. A bent Hawley wire can move teeth in the wrong direction. In each case, book a check. Our guide to Essix vs Hawley retainers explains how each type wears and when to replace it.

What if your bonded retainer has come loose?

If one bond on a fixed retainer has come away, that tooth is no longer held and can move. Wear your removable retainer full time if you have one, and book a repair. Repairs usually take one short appointment. If the wire is broken or bent, it may need to be replaced. Our guide to permanent retainers explains the pros, cons and care of bonded wires.

Can you replace a retainer if treatment was done elsewhere?

Yes. A retainer is made from the current position of your teeth, so we do not need records from your original provider. It helps to bring any information you have, such as what type of retainer you had and how often you were told to wear it. If you had treatment abroad and have no aftercare arranged in London, we can take over your retention checks.

Teeth moved after losing a retainer: what now?

A short course of aligners can often correct minor relapse in a few months. See Invisalign cost in the UK and London for typical fees.

How often should retainers be replaced?

Clear retainers typically last one to three years. Hawley retainers last longer, often several years. Bonded wires can last many years with checks. Signs it is time to replace include cracks, holes, cloudy plastic that will not clean, a loose fit or a bent wire. Our retainer costs guide covers each type, its lifespan and how prices compare across the UK.

How to make your next retainer last longer

• Keep it in its case whenever it is out of your mouth
• Clean it with cool water and a soft brush; never use hot water
• Do not drink anything except water while wearing a clear retainer
• Keep it away from pets, which are attracted to the smell
• If you grind your teeth, ask about thicker material or a Hawley
• Ask us to keep your scan on file for quick spares

Do you need a spare retainer?

Many people who have lost a retainer once order a spare. A second clear retainer made from the same scan means you can swap immediately if one is lost or damaged, and is usually cheaper than paying for urgent replacements later. Spares are particularly useful for students, frequent travellers and anyone with a teenager who wears one.

Retainers for teenagers

Teenagers lose and break retainers more often than any other group, and their teeth are still settling after treatment. If your child's retainer is lost, book quickly, ask for a spare and consider a bonded wire if wearing a retainer at night is a struggle. It also helps to agree a routine: retainer in the case on the bedside table every morning, never wrapped in a tissue at lunch.

Do retainers need to be worn forever?

Most orthodontists now recommend long-term retention, because teeth keep moving slightly throughout life. After the first year, many people wear a removable retainer a few nights a week. A replacement is a small cost compared with having treatment again.

Why are replacement retainers charged separately?

Your original orthodontic fee usually covers the first set of retainers and a period of retention reviews. After that, retainers wear out like any other appliance, and replacements are charged per retainer. The fee covers the appointment, the scan, the laboratory or in-house manufacture and the fitting check. Keeping your scan on file reduces the cost and time of future replacements.

Which areas do you cover?

We arrange retainer appointments for patients across central, west, north, south and east London. When you enquire, tell us where you live or work and the times that suit you. See all areas of London we cover.

Keeping a spare retainer

Many patients keep a spare retainer for travel or emergencies. Ask us whether a spare can be made from the same scan, which is usually quicker and cheaper than starting again.

Book a replacement retainer

Tell us what happened to your retainer, which type you had and when your treatment finished, and we will arrange a scan. Request an appointment through our online form and choose your preferred area of London.
