Key takeaways
Preparation and packing
Pack in carry-on: Always keep your current and, if possible, next set of aligners in your carry-on luggage, never in checked baggage, to avoid losing them during travel.
Bring extra trays: Pack the previous, current, and next sets of aligners in case of loss or damage.
Assemble a survival kit: Include a toothbrush, travel-sized toothpaste, floss, cleaning tablets, and your case in a small bag for easy access.
Use a case always: Never wrap aligners in a napkin while eating, as they are easily misplaced or thrown away.
Eating and drinking
Remove for meals: Take aligners out for all meals and drinks, except for plain water.
Plan dining: If you are on a long flight, try to eat before boarding or shortly after takeoff to avoid managing aligners in a cramped, unhygienic restroom.
Clean on the go: If you cannot brush, rinse your mouth and the aligners thoroughly before putting them back in.
During the trip
Maintain wear time: Keep your aligners in for 20-22 hours per day, even while on holiday.
Stay hydrated: Drink plenty of water to keep your mouth clean, which also prevents dry mouth and keeps aligners clean.
Clean before reinserting: Always brush your teeth after eating before putting aligners back in to avoid trapping bacteria.
Manage time zones: If switching trays at night, follow your home time zone for the first few days of your trip.
Use chewies: Bring chewies to ensure your aligners are properly seated, especially if you are changing them while away.

Why travel requires extra aligner planning
Travel can easily interrupt your normal routine, which is why aligner users need a bit of extra planning before a trip. Clear aligners must be worn for about 20-22 hours a day, but flights, road trips, and busy travel schedules can make it easy to forget your wear time.
Eating habits also change while traveling. Trying new foods or snacking more often means removing your aligners more frequently, so it's important to have a safe place to store them and maintain proper oral hygiene.
In addition, access to a bathroom for brushing or rinsing your aligners may not always be available. This is where a protective case helps. Carrying an aligner case like the Caspersmile travel case keeps your trays clean and secure whenever you remove them during meals or coffee breaks. It also helps maintain hygiene when a sink or bathroom isn't easily available.
Travel smart with your aligners
Choose the Caspersmile aligner case, which keeps aligners clean, safe, and easy to carry during flights and busy travel days.
Pack a dedicated aligner travel kit
One of the simplest ways to maintain aligner care while on vacation is by carrying a small travel kit. Having essential hygiene tools in one place makes aligner maintenance quick and convenient wherever you are.
A well-prepared kit ensures that you never need to search for supplies after meals or during long travel days.
Aligner travel kit essentials
Your kit should include:
-
A travel-size toothbrush
-
Fluoride toothpaste
-
Dental floss or floss picks
-
A soft brush for cleaning aligners
-
A protective aligner case
-
Chewies
Keeping these items together reduces the chances of skipping oral hygiene. After meals, you can quickly brush and put your trays back in without disrupting your schedule. For convenience, store your kit in your hand luggage or backpack so it remains easily accessible during flights, road trips, or sightseeing days.
Always store aligners in their case
One of the most common mistakes people make when traveling with clear aligners is leaving them exposed. It might seem harmless to place them on a table during a meal, but unprotected trays are extremely easy to lose.
Wrapping aligners in napkins is especially risky. Many trays have been accidentally discarded this way, particularly in busy cafés or restaurants.
A protective case provides a simple but effective solution.
Smart storage habits
Developing a few habits can prevent unnecessary setbacks:
-
Always place trays inside a protective case when removed
-
Avoid storing aligners in pockets or loose bags
-
Keep the case closed when not in use
These small habits protect aligners from damage and help prevent accidental disposal. If you frequently travel or dine out, investing in a durable safe storage travel case can make aligner management significantly easier.
Bring a backup set of aligners

Even with careful planning, accidents can happen during travel. Aligners may become misplaced, damaged, or accidentally discarded. Carrying a backup set provides reassurance and flexibility.
Your previous trays can serve as a temporary replacement if the current set becomes unavailable. This prevents teeth from shifting while you contact your provider for guidance.
A backup pair takes up very little space but can save significant time and stress during a trip. For travellers spending extended periods away from home, this precaution is particularly valuable.
Travel with peace of mind
Ensure your smile stays on track with Caspersmile backup aligners, compact and ready to replace lost or damaged trays while you're on the move.
Stay hydrated while travelling
Hydration plays an important role in aligner comfort, especially during flights. Airplane cabins are known for their low humidity levels, which can contribute to dry mouth.
Dry mouth may make aligners feel tighter or more noticeable, and it can also increase the risk of bacterial buildup.
Hydration tips for aligner wearers
To stay comfortable while travelling:
-
Drink water regularly throughout the day
-
Sip water frequently during flights
-
Limit sugary drinks, alcohol, and excessive caffeine
Water is the only beverage you should consume while wearing aligners. Staying hydrated not only improves comfort but also supports overall oral health.
Maintain oral hygiene on the go
Travelling often means eating at different times or trying new foods throughout the day. While this is part of the fun, frequent snacking can increase the risk of plaque buildup under aligners.
Good oral hygiene remains essential even when routines change.
How to clean aligners while traveling

Maintaining cleanliness does not have to be complicated:
-
Brush your teeth after meals whenever possible.
-
Rinse aligners with water if brushing is unavailable.
-
Clean trays daily with a soft brush and mild soap
-
Avoid using hot water, as heat can warp the plastic material and affect the fit of your aligners.
-
Regular cleaning keeps trays clear, reduces bacteria buildup, and helps maintain healthy teeth and gums during your trip.
-
Use Caspersmile cleaning tablets for a thorough soak to keep aligners fresh, clear, and bacteria-free.

Managing aligners during flights
Flying with clear aligners requires a few small adjustments, particularly when meals or drinks are served onboard. Since aligners should not be worn while eating or drinking anything other than water, you may need to remove them temporarily during in-flight meals.
In-flight aligner tips
During flights:
-
Remove aligners before eating.
-
Place them in a protective case immediately.
-
Avoid placing aligners on tray tables.
-
Rinse aligners with bottled water if necessary.
Airport security typically does not require removing aligners from your mouth. However, if your travel case is inside your bag, it may be inspected during routine screening.
Keeping your case accessible makes the process easier.
Handling time zones and tray changes
Travelling across time zones can disrupt daily schedules, making it easier to forget aligner routines or tray-change dates.
However, consistency remains important for effective treatment.
Staying on schedule while travelling
To maintain progress:
-
Follow your usual tray-change schedule whenever possible.
-
Set phone alarms as reminders
-
Track wear time with a mobile timer
If your trip significantly alters your daily routine, focusing on the 20-22-hour wear guideline will help keep treatment on track.
Technology can also be helpful. Simple reminders help ensure that, even on busy travel days, aligners remain part of your routine.
Avoid heat exposure while travelling
Clear aligners are made from medical-grade thermoplastic material that can warp when exposed to high temperatures. Heat exposure may cause trays to lose their shape, which can affect how they fit on your teeth.
Protecting aligners from heat
To prevent damage:
-
Never leave aligners inside a hot car.
-
Avoid placing them near heated surfaces.
-
Keep them away from direct sunlight.
A protective case not only prevents loss but also shields aligners from environmental factors that may damage them.
Final thoughts: Travel stress-free with your aligners
Traveling should be an enjoyable experience, not a source of stress for aligner wearers. While trips naturally disrupt routines, clear aligner treatment can continue smoothly with the right preparation.
Using the best travel cases for aligners, keeping trays secure, staying hydrated, and sticking to your daily wear schedule all help ensure your treatment stays on track while traveling.
Clear aligners are designed for flexibility. With thoughtful planning, they can easily fit into busy travel schedules, long flights, and spontaneous adventures. Wherever your journey takes you, maintaining good aligner habits will help your treatment progress and your smile move closer to its final result.
