Quick Answer: Rinse clear aligners with lukewarm water whenever you remove them, then gently clean them with a soft toothbrush and a cleaner recommended by your orthodontist or aligner manufacturer. Avoid hot water, toothpaste, bleach, and abrasive products because they can warp, scratch, or cloud the trays. Brush your teeth before reinserting the aligners, and keep them in their case whenever they are out of your mouth.
How to Clean Clear Aligners Each Day
Clear aligners remain in close contact with your teeth for most of the day, so saliva, plaque, and food residue can quickly collect on them. A simple daily routine helps prevent odor, discoloration, and buildup.
Follow these steps:
- Remove the aligners and rinse them with lukewarm water.
- Gently clean the inside and outside surfaces with a soft toothbrush or the method recommended for your aligner system.
- Use an aligner cleaner recommended by your orthodontist or the tray manufacturer when needed.
- Rinse the trays thoroughly so no cleaning product remains.
- Brush and floss your teeth before putting the aligners back in.
Use a separate toothbrush for your aligners rather than the same brush you use on your teeth. Clean gently, because aggressive scrubbing can leave scratches that make the trays appear cloudy.
If you use cleaning crystals or tablets, follow the product instructions for the amount of water and soaking time. Do not use denture-cleaning products unless your orthodontist or aligner manufacturer confirms they are safe for your trays.
Products to Avoid
Some common cleaning products can damage clear aligners or leave unwanted residue.
Avoid using:
- Hot or boiling water
- Toothpaste
- Bleach
- Abrasive powders
- Hard-bristled brushes
- Alcohol-based mouthwash
- Strongly colored soaps or rinses
- Household cleaning products
Hot water can distort the plastic and change how the aligners fit. Toothpaste and abrasive cleaners may create small scratches that make the trays look dull or cloudy. Bleach, harsh chemicals, and alcohol-based products may damage the material or irritate your mouth if residue remains.
Mild dish soap may be appropriate for some aligner systems, but patients should confirm the recommended cleaning method before using it regularly.
Keep Your Teeth Clean Before Reinserting Aligners
Cleaning the trays is only part of clear-aligner care. Wearing aligners over unclean teeth can hold food residue and sugary or acidic liquid against the enamel, increasing the risk of plaque buildup, decay, odor, and gum irritation.
Remove your aligners before eating and before drinking anything other than plain water unless your orthodontist gives you different instructions. Brush your teeth before reinserting the trays and floss at least once each day.
When you cannot brush immediately, rinse your mouth and aligners thoroughly with water, then clean both as soon as practical. Continue following the daily wear schedule prescribed by your orthodontist.
How to Prevent Stains, Cloudiness, and Odors
Coffee, tea, soda, sports drinks, wine, tobacco residue, and strongly colored foods can stain clear aligners. Dried saliva and plaque may also create odor or visible buildup.
To keep your trays clearer:
- Remove them before eating or drinking anything except water.
- Rinse them as soon as you take them out.
- Clean them before residue dries on the plastic.
- Keep the storage case clean and dry.
- Avoid smoking or vaping while wearing the trays.
- Do not scrub cloudy aligners aggressively.
Cloudiness that does not improve after proper cleaning may come from scratches, staining, mineral buildup, or normal wear rather than remaining debris. Contact the orthodontic office if the trays remain cloudy or develop an odor despite consistent cleaning.
Store Aligners in Their Case
Place aligners in their protective case whenever they are not in your mouth. Do not wrap them in a napkin or leave them loose on a table, in a pocket, or inside a bag.
Wash the case with mild soap and lukewarm water, rinse it thoroughly, and allow it to dry before placing clean aligners inside. Avoid hot water and harsh disinfectants.
Keep the trays and case away from direct sunlight, hot vehicles, and other sources of heat. Excessive heat can distort the plastic.
If an aligner falls on the floor, rinse and clean it thoroughly before reinserting it. Contact Miler Orthodontics if the tray is exposed to chemicals, chewed by a pet, visibly damaged, or contaminated in a way that cannot be safely cleaned.
When to Contact Your Orthodontist
Contact Miler Orthodontics if an aligner:
- Cracks or develops a sharp edge
- Becomes warped
- Stops fitting properly
- Is lost or accidentally discarded
- Causes ongoing irritation
- Remains cloudy or odorous after proper cleaning
- Is damaged by heat, chemicals, or a pet
A cracked, warped, or poorly fitting tray may not apply the intended forces to your teeth. Do not automatically move to the next tray or return to an older one unless the orthodontic team instructs you to do so.
Keep Your Aligners Clean Throughout Treatment
A consistent routine is more important than using numerous cleaning products. Rinse your aligners when you remove them, clean them gently each day, avoid damaging heat and chemicals, and brush your teeth before putting them back in.
Contact Miler Orthodontics if your aligners crack, warp, stop fitting, or remain cloudy or odorous after proper cleaning. Our team can tell you whether the tray is safe to continue wearing or needs to be replaced.
