Travelling with a retainer: case, cleaning and a loss plan

A retainer is a small, clear, easy-to-lose object that spends half its life in your mouth and the other half in places it should not be. On holiday there are more of those places: the napkin on the restaurant table, the tray on the plane, the pocket of a jacket, the bed in a hotel room where the cleaner strips the sheets. This guide pulls together what two NHS orthodontic leaflets say about looking after a removable retainer, notes where they differ, and adds a short checklist for travel that is our own suggestion.

It is general information, not a substitute for the instructions from your own orthodontist, which come first.

What the NHS leaflets agree on

We read the patient leaflets from University Hospitals Plymouth NHS Trust (Your removable retainers) and NHS Lothian (All About Retainers). They agree on the basics:

• Keep it in a box. Plymouth says to keep retainers safely in a box when not wearing them. NHS Lothian says to take it out for sports and keep it in the protective box.
• Do not wrap it in tissue. Both say it will be mistaken for rubbish and thrown away.
• Do not put it in a pocket or loose in a bag. Plymouth says you may sit on it and break it, and NHS Lothian says it will be damaged or may not fit afterwards.
• Keep it away from pets. Plymouth says dogs really like the taste, and NHS Lothian says to keep it away from cats and dogs.
• Do not use very hot or boiling water. NHS Lothian says it may distort the plastic so the retainer may not fit.
• Do not eat or drink while wearing it. Plymouth says food and drink collect in retainers, and NHS Lothian says clear plastic retainers should come out for eating and drinking.
• Tell your team if something goes wrong, and bring the retainer to every appointment.

Where they differ: cleaning

Leaflet	Cleaning advice
Plymouth	Take retainers out to clean your teeth, brush them with your toothbrush and cold water, and use a special cleaner such as Retainer Bright or Sterident to freshen them
NHS Lothian	Clean after meals with a toothbrush and soapy water, and avoid toothpaste because it tends to scratch the surface

These two are not the same, so we do not pick a winner. Follow the method your own orthodontic team gave you, and carry whatever it calls for.

A travel checklist

These points are our own suggestions, based on the NHS storage rules above:

1. Take a spare box, or a sturdy case with a snap lid, and put the retainer in it every time it is out of your mouth.
2. Pick a habit and keep it: retainer out, box open, retainer in, box shut, box into the same inside pocket. Do it before you pick up a napkin or a drink.
3. Never leave it on a tray, napkin or bed. Those are the places it gets cleared away.
4. Carry it in hand luggage, not the hold, along with your toothbrush. Our travel oral-care kit checklist lists the rest, and oral care on a flight covers dry mouth and liquids.
5. Use cold water to rinse, and judge the tap water as you would for brushing; brushing your teeth abroad explains when bottled water is the better choice.
6. Pack a tiny cleaning kit: a soft toothbrush, a small bottle of soap or the cleaner your orthodontist recommended.
7. Keep your orthodontic team’s contact details on your phone and in your wallet.

Protect it from the wet

Rain makes everything in a bag worse, and a case rattling around beside a dripping umbrella is a hazard. Keep the retainer box in an inside pocket or a small zip pouch, and put the wet umbrella and anything damp in a separate compartment or plastic bag. A compact umbrella that clips to the outside of a bag, rather than going inside it, avoids the mix completely. Calm Eden’s guide to bringing an umbrella on a plane covers carry-on rules.

For openness: Calm Eden, which sells the umbrella below, has the same owner as FlosserGuide. The Haven Umbrella folds to 40 cm (15.75 in), weighs about 390 g and opens and closes with one press, and a swivel carabiner handle lets it clip to a bag. Those are the seller’s figures, and no retainer care depends on any umbrella.

If it goes missing

The leaflets say to contact your team as soon as you can, and warn that you may have to pay for replacements if a retainer is lost or damaged beyond repair through carelessness. Our suggestions, in order: retrace your steps, ask the hotel or restaurant, check bins and bedding if you can, then contact your orthodontist or dentist. Do not use a bent or poorly fitting retainer, and do not try to reshape it yourself.

In short

• Box every time, in the same pocket, in hand luggage.
• No tissue, no pockets, no hot water.
• Rinse as your orthodontist told you, cold water if in doubt.
• Rain: keep it away from the wet umbrella.
• Lost: tell your team as soon as you can.
