How Should I Handle Aligners During Illness?

Wearing clear aligners (such as Invisalign or similar brands) is a significant commitment — typically 20–22 hours per day — to ensure your treatment stays on schedule and delivers the desired results. But what happens when you fall ill? Whether you have a common cold, flu, sore throat, stomach virus, vomiting or fever, illness complicates your aligner treatment. Patients often ask: “How should I handle aligners during illness?” This guide from Comfort Dental Weymouth (Weymouth MA) covers everything you need to know — when to keep wearing your trays, when it’s safe to temporarily remove them, how to maintain hygiene, and how to protect your treatment progress while you recover.

Why Illness Matters for Aligner Wear

When you’re well, wearing aligners consistently is straightforward: remove them for meals or drinks other than water, clean your teeth, and then reinstate the trays. But during illness, a few key issues arise:

Reduced wear time: If you remove your aligners too much because of discomfort, it can delay treatment or affect tooth movement.
Increased bacterial load or acid exposure: Illness can involve vomiting, increased mouth-breathing, dry mouth, cough drops or sugary medications — all of which can increase risk of tooth decay, enamel erosion or trapped bacteria under aligners.
Hygiene challenges: Your hands may handle tissues, cough, vomit; the aligner case may sit on a bedside table; you may skip brushing due to fatigue. These factors elevate risk.
Comfort & fit issues: If you’re congested, breathing through your mouth, or your aligner edges rub a sore throat, you may feel more discomfort, tempting you to leave trays out longer.

Given these risks, managing aligners during sickness isn’t just about convenience — it protects your oral health and maximises your treatment outcomes.

Should You Continue Wearing Your Aligners When You’re Sick?

The general rule

Yes — in most cases you should continue wearing your aligners even when you’re ill. Several credible sources emphasise that illness is not a reason to abandon the wear schedule. For example, one blog says: “you should not stop your Invisalign treatment while you are sick and recovering.”
Similarly: “Wearers of removable orthodontic appliances should continue to wear their devices but clean them more frequently.”

When it’s okay to remove or pause them

There are exceptions. You may consider temporarily removing your aligners when you have:

Repeated vomiting (which deposits stomach acid on teeth and aligners) — you might want to remove trays until you’re stable.
Severe throat pain, sinus congestion or swelling makes wearing aligners too uncomfortable or causes you to avoid them altogether.
A very contagious infection and you prefer to minimise handling trays until you recover (though this is more of a comfort/precaution than a strict orthodontic necessity).

Even when you remove the trays, you should aim to re-insert them as soon as practical, and track your wear hours so you still maintain something close to the 20-22 hours/day goal.

What to discuss with your orthodontist

If illness persists for several days, or you must leave trays out for an extended period (say over 24–48 hours), call us at Comfort Dental Weymouth. We may recommend:

Skipping a planned aligner advancement if you’ve missed wear hours.
Continuing with the current tray set longer before advancing to the next.
A supplemental aligner to “catch up” on lost wear time.
A brief “pause” in movement with the same tray until you recover.

Practical Steps for Aligner Care During Illness

When you’re under the weather, the day-to-day aligner routine needs extra care. Here’s a detailed checklist for patients of Comfort Dental Weymouth in Weymouth MA.

Maintain the wear schedule (with flexibility)

Keep wearing your aligners as much as possible.
If you remove them because you’re drinking hot tea, using cough drops, or vomiting, take note of the hours lost.
Make up lost time by ensuring you wear the trays overnight (they count as part of the 20-22 hours).
Avoid leaving trays out “just because you feel tired” — skipping wear will impact treatment.

Clean your trays more often

Being sick means more germs, higher bacterial load and potentially more exposure. Key tips:

Rinse your aligners immediately after removing them (for meals, drinks or medications) in lukewarm water.
Brush the trays gently with a soft-bristled toothbrush and clear mild soap or aligner cleaner. Avoid toothpaste if possible (some components may scratch trays).
At end of day soak your trays in an aligner-cleaning solution (or a safe DIY mix if advised). This helps reduce microbial load.
Clean your aligner case too — the place you store trays is often forgotten but a reservoir for germs. Some sources note desks and night-tables have far more germs than toilet seats during flu season.
After vomiting: Wait 30 minutes before brushing your teeth (to avoid spreading acid) and ensure you clean your trays thoroughly.

Maintain oral hygiene

Brush your teeth and floss at least twice daily — when ill you might feel lazy, but this is more important than ever.
If you cough or breathe through your mouth, dry mouth can accelerate bacterial growth. Drink more water, use sugar-free rinses or gums (xylitol) if approved.
After vomiting: rinse your mouth with water or mouthwash, wait 30 mins, then brush. Don’t brush immediately after vomiting.

Manage eating, medications and beverages

When ill you may rely on throat lozenges, cough syrups, hot teas or soft foods — but many of these contain sugar or acidic ingredients which can harm teeth under trays. Choose sugar-free or low sugar versions.
Avoid drinking beverages other than water while wearing aligners (unless your clinician approves). If you consume anything other than water, remove trays, clean teeth and trays, then reinsert. (Same rule as regular usage, but more critical when illness increases risk.)
For hot drinks: hot liquids can warp aligner plastic — during recovery, avoid wearing trays while drinking hot tea if possible; remove them temporarily.

Breathe easier & reduce discomfort

If your illness causes mouth-breathing, congestion or dry lips, this can irritate the aligner edges. Use colourless lip balm (so it won’t stain trays) and drink more water to maintain saliva flow.
If aligner edges irritate your throat or cheeks, you may apply orthodontic wax to soften the edge and reduce irritation temporarily. (While this is more common in braces, it’s useful for aligner discomfort too.)

Track your wear hours and progress

Use a simple log (paper or phone note) to record hours your trays were out due to illness each day.
Compare to your usual wear goal (20-22 hours/day). If you fall behind across multiple days, contact Comfort Dental Weymouth for guidance.
Avoid skipping to the next aligner early if you’ve lost significant wear hours — you may need to stay longer in the current tray to maintain movement quality.

Special Scenarios & How to Handle Them

You vomit

Vomiting is particularly challenging because it deposits stomach acid on your teeth and potentially trays. Here’s how to manage:

Remove aligners immediately.
Rinse mouth with water or baking soda mix. Do not brush for 30-60 minutes.
Clean your aligners thoroughly — soak, brush gently, rinse. If trays seem distorted or stained, call the office before reinserting
Once you’re stable, reinsert carefully and track lost wear time.

You have a sore throat, cough or sinus infection

Wearing trays while coughing or throat sore may be uncomfortable. You can consider short-term removal (for comfort) but try to minimize total time out.
Use sugar-free lozenges or saline gargles rather than sugary cough drops which can increase decay risk under trays.
Clean trays more often because coughing can increase saliva and bacteria contact with aligner interior.

You are on sugar-containing cough syrup or lozenges

If medication contains sugar: remove trays to take the meds, rinse/brush afterwards, insert trays again.
Better: use sugar-free versions when possible.
Be especially cautious at night when wearing trays — sugar residue + tray coverage = risk for decay.

You’re prescribed antibiotics or other medications

Continue wearing trays unless your provider advises otherwise. The aligner schedule is still critical.
Some antibiotics may cause dry mouth or changes in oral flora; increase hydration, maintain hygiene, clean trays more frequently.
If medication causes mouth sores, your trays may irritate these. Using wax on edges or temporarily pausing wear (with tracking) may help.

You have fever or are very fatigued

Fatigue can lead to skipped brushing, extended tray removal, snacking irregularly. Resist the temptation: set simple alarms for brushing, document tray hours, keep water nearby.
If you must temporarily pause for comfort, aim for the shortest duration feasible and resume full wear when you’re able.

What Happens If You Miss Wear Time During Illness?

Missing aligner wear time doesn’t necessarily ruin your treatment — but it does require attention and correct handling:

If you miss just a few hours one day, you can often make up by wearing extra hours the next day (overnight counts).
If you miss many hours (e.g., trays were out several long stretches), you may risk slower tooth movement, potential fitting issues when you advance trays, or delays in overall treatment time.
If wear time drops significantly, your dentist/orthodontist may recommend extending the current tray wear beyond its originally planned duration to catch up, rather than jumping to the next tray prematurely.
Communicate with Comfort Dental Weymouth: we’ll evaluate your progress, check tray fit, ensure you’re still on track, and adjust the treatment plan if needed.

In short: illness‐related interruptions are manageable if handled proactively.

Frequently Asked Questions (FAQs)

Can I skip a day of wearing aligners because I’m too sick?
A: Technically yes, you can, but you should aim to avoid skipping a full day. One day off won’t ruin treatment, but consistent gaps may lead to delays. Make up the time as soon as possible and call the office if you can’t keep up.
Should I advance to the next aligner even if I missed hours due to illness?
A: No — if you lost significant wear time, stay in the current aligner longer until you’ve achieved the prescribed hours, or consult your team at Comfort Dental Weymouth for adjustment.
Can I drink hot tea or soup with my aligners in when I’m sick?
A: It’s best to remove trays when consuming hot drinks or anything other than water, especially when sick. Hot liquid may warp the aligner and warm drinks often involve sugar or medications that can harm teeth under trays.
What cleaning routine should I follow for my aligners while recovering?
A: Rinse trays each removal, brush gently with soft toothbrush and mild soap, soak nightly in recommended solution, disinfect your case, clean your hands thoroughly, and ensure your oral hygiene remains extra diligent.
My aligners feel loose after being sick — what should I do?
A: If your trays fit poorly or feel distorted, stop wearing them and call Comfort Dental Weymouth. You may need a replacement tray or adjustment before continuing.
Are sugar-free cough drops safe with aligners?
A: Yes. Choose sugar-free cough drops to minimise risk of decay under aligners. Remove your trays if possible when taking cough drops, rinse afterwards, and reinstate trays as soon as you can.
How does vomiting affect my aligner treatment?
A: Vomiting exposes your teeth and trays to stomach acid which is corrosive; you should remove trays during episodes, rinse mouth carefully, wait before brushing, clean trays thoroughly, and then continue wear as soon as possible.
Can mouth‐breathing from a cold ruin my trays or my treatment?
A: Mouth‐breathing can dry your mouth and increase bacterial risk but doesn’t “ruin” trays. To manage, increase hydration, maintain oral hygiene, clean trays more often, and resume regular wear when you can.
Do I need to replace my toothbrush or aligner case after being sick?
A: Yes, it’s a good idea. Change your toothbrush (or toothbrush head) after illness, and thoroughly clean or replace your aligner case to avoid re-introducing germs.
When can I safely resume full aligner wear after being sick?
A: As soon as you are comfortable, can tolerate wearing the trays for most of the day, are able to maintain hygiene and are symptom‐improving. If you’ve lost many hours of wear, consult Comfort Dental Weymouth for guidance on recommencing your routine.
