Can You Use Cough Drops with Invisalign?

The good news is that you can use cough drops with Invisalign aligners as long as you choose the right kinds. Opt for clear, dye-free options that are also sugar-free. Sugary cough drops are always a bad idea as the sugar can get trapped between your teeth and aligner, leading to cavities and decay. Beyond that, look at the ingredients and flavoring carefully. Strong spices, essential oils, menthol, eucalyptus, and dyes can all stain or discolor your aligner trays.

Stick to major brands like Halls, Luden’s, Cepacol, Ricola or Sucrets, which offer clear, sugar-free varieties. For example, Halls Sugar Free cough drops contain menthol but no dyes. Luden’s offers both menthol and pectin options in clear, sugar-free forms. Cepacol’s Maximum Strength cough drops also have menthol but no dyes. These are all safer bets for Invisalign patients than more obscure brands which may contain coloring agents. If in doubt, ask your orthodontist before using any cough drop.

Which Cough Drop Ingredients Should You Avoid with Invisalign?

While sugar-free and clear are the main requirements, you also need to beware of certain ingredients and flavors when choosing cough drops:

  • Menthol and eucalyptus oils – These strong flavorings can potentially stain aligners or impact their fit. Menthol is typically fine in small doses but avoid overtly menthol-heavy options.
  • Essential oils – Oils like thyme, lemon, and cherry extracts can discolor trays. Avoid “all-natural” cough drops heavy in potent essential oils.
  • Dyes – Obviously any artificial dyes raise a red flag for Invisalign patients. Always check the ingredient list for terms like “dyes”, “colorings” or specific color chemicals.
  • Benzocaine – This anesthetic is sometimes used in cough drops but may cause teeth sensitivity. Opt for products without it.

When unsure about a cough drop ingredient, the prudent move is to avoid it or check with your orthodontist first. Use a trusted brand and select the blandest flavor possible. Menthol, herbal, honey, or pectin flavors tend to be low-risk with Invisalign.

How Should You Consume Cough Drops with Invisalign Trays In?

Once you’ve chosen a cough drop free of dyes and risky oils, there are some best practices for consuming it with your aligners in:

  • Rinse your mouth out with water before placing the cough drop in your mouth. You want to prevent any food debris or residue on your teeth from interacting with the cough drop and potentially staining.
  • Allow the cough drop to fully dissolve in your mouth rather than chewing or crushing it. Breaking it up may allow its colors or oils to contact more aligner surface area.
  • Never eat the cough drop’s wrapper or stick! Discard properly before the drop goes in your mouth.
  • When the cough drop has dissolved, thoroughly rinse your mouth again and brush if possible, to clear away any remnants left behind.
  • Avoid cough drops with hard outer shells or coatings which could potentially damage aligner trays when dissolved.
  • After removing aligners, inspect them and brush well before reinserting. If any discoloration is evident, use an aligner-cleaning product.

By minimizing the contact the cough drop has with your actual trays, you lower the odds of any staining or residue issues occurring. Still, proper oral hygiene before and after is key.

How Often Can You Use Cough Drops with Invisalign?

You don’t want to overdo it on the cough drops or leave aligners in longer than advised while consuming them. Follow these precautions:

  • Stick to the 22-hour daily wear schedule set by your orthodontist. Don’t keep trays in longer just because you have a cough drop.
  • Once your cough symptoms improve, stop relying on cough drops. Don’t use for more than a few days.
  • Don’t use more than 1 or 2 cough drops per day. The menthol and flavorings can build up.
  • Avoid constant snacking on cough drops. Allow your saliva flow to return to normal between each one.
  • Always remove aligners before sleeping, even if you’ve recently had a cough drop. Don’t sleep overnight with cough drops in your mouth.

With moderation and proper oral hygiene, the occasional cough drop to ease a sore throat is fine. But overusing them or improper use can heighten staining risks. Follow your orthodontist’s Invisalign guidelines and track your tray wear diligently even when taking cough drops.

What About Other Oral Cough Remedies Like Lozenges or Syrups?

Cough drops aren’t the only oral cough treatment out there. You may also be wondering about:

  • Lozenges – Opt for clear, sugar-free varieties from reputable brands. Avoid any with menthol or essential oils. Consume carefully and rinse mouth after.
  • Throat sprays – These are fine as long as they are sugar-free. Don’t spray excessively with aligners in. Rinse mouth after.
  • Cough syrup – Avoid since the liquid sugar could get trapped between teeth and trays. Only use sugar-free types after consulting your orthodontist.
  • Hard candies – Not recommended as they can stick to aligners and are high in sugar. Best to avoid entirely.
  • Teas – Herbal teas can be soothing and are fine to drink with Invisalign with caution. Don’t steep any tea bags against your aligners. Rinse mouth after.

For maximum safety, consult your orthodontist about any new oral remedy you want to try, from lozenges to teas. And rinse mouth thoroughly after anything other than water touches your teeth with aligners in.

What If You Get a Stain on Your Aligners from a Cough Drop?

Hopefully by following all the precautions, you won’t end up with stained or discolored aligners from your cough relief efforts. But if you do notice stains or residue:

  • Brush the aligners – Gently brush with a soft aligner-specific toothbrush and toothpaste. Avoid abrasive scrubbing.
  • Use cleaner – Apply cleaner like Retainer Brite or Polident 3 Minute Cleaner according to package directions. Soak aligners for recommended time.
  • Don’t bleach – Never use bleach or hydrogen peroxide, which can damage the plastic.
  • Switch aligners – If stain won’t fade, inform your orthodontist and switch to your next aligner set early.
  • Be diligent – Clean and examine aligners carefully each time you remove them. Catch stains ASAP.

Hopefully some extra TLC will make any discoloration disappear. But if not, it’s critical to talk to your orthodontist rather than try to overlook it. Leaving stained trays in your mouth can impact results and be unhealthy. Remember, staining or wearing out aligner sets early may require new impressions and replacement aligners at your expense. So avoiding stains is in your best interest!

When Should You Ask Your Orthodontist About Using Cough Drops with Invisalign?

Invisalign treatment depends on patients being responsible and vocal about their issues and concerns. Don’t sit silently if you have questions or problems! Instead, reach out to your orthodontist’s office if:

  • You are unsure if a cough drop brand or flavor is Invisalign-safe. Ask before trying it!
  • You experience staining or damage after using a cough product. Don’t ignore – report it!
  • You need prolonged cough relief lasting more than a few days. Discuss options.
  • Your cough is severe or symptoms worsen. The orthodontist may evaluate if Invisalign should pause.
  • You have recurring sore throats or coughs. There could be an underlying problem.

In general, plan to discuss your overall illness history and anything that might impact your mouth or aligner wear at appointments. Don’t gamble with over-the-counter products that could set your treatment back. Stay vigilant against damage and stains. And ask for help if you need it – that’s what your orthodontist is there for!

Can an Orthodontist Prescribe Special Cough Drops for Invisalign Patients?

If you’re concerned about over-the-counter cough products, it is possible your orthodontist can prescribe you medical-grade options designed for oral appliances. Examples include:

  • OraMoist Dry Mouth Cough Drops – Specifically formulated for dry mouth relief.
  • XyliMelts Mouth sore discs – Adhere directly to gums for slow menthol release.
  • Salivart Oral Rinse – Rinses to clear excess throat mucus.
  • MuGard – Mucoadhesive liquid to coat and numb sore throat areas.
  • NeutraSal – pH neutralizer to help soothe throat discomfort.

While more expensive than drugstore brands, these products are free of dyes and designed for oral appliance compatibility. Talk to your orthodontist to see if special prescription cough relief is recommended in your unique case.


Cough and cold discomfort can disrupt your Invisalign progress if you treat it the wrong way. But by understanding the do’s and don’ts of cough drops, you can soothe your symptoms without sabotaging yourself. Choose clear, sugar-free options from trusted brands. Carefully dissolve in mouth and rinse after use. Limit frequency and duration of use. And inspect aligners diligently for any staining issues. With smart precautions, you can keep your aligners crystal clear while quieting that cough. Don’t hesitate to discuss concerns with your orthodontist so you stay healthy and on-track. Use cough drops when you need them – but use them wisely!
