If you are wondering how to clean clear aligners, start with the instructions from your own orthodontist and the manufacturer of your appliance. For most aligners, a simple daily routine is to remove them, rinse with cool or lukewarm water, gently clean with a soft brush and an approved mild cleaner, rinse thoroughly, and store them in their case when not worn. Hot water can distort plastic. Cleaning the aligners does not replace brushing and flossing your teeth.
How to clean clear aligners each day
Quick answer: Rinse the aligners after removal, clean all surfaces gently, rinse away any cleaning product, and put them back only after your teeth and gums are clean. Check instructions for your specific brand before using a soaking product, soap, or cleaning tablet.
- Wash your hands before handling the aligners.
- Remove them carefully and rinse both sides under cool or lukewarm water. Do not use hot or boiling water.
- Use a separate soft toothbrush and the cleaner your orthodontist recommends. Brush lightly around the inner grooves.
- Rinse completely so no cleaner is left on the plastic.
- Keep them in a clean protective case whenever they are out of your mouth.
Clean the case regularly according to its instructions and let it dry. A dirty case can undo a careful aligner-cleaning routine. If your aligners have attachments or a special coating, your clinician may recommend a different product or technique.
What should you avoid when cleaning aligners?
Do not use hot water, bleach, household disinfectants, abrasive powders, or a hard brush. Hot water can alter the appliance’s fit; harsh chemicals can be unsafe if residue remains. Toothpaste may be too abrasive for some clear plastics and leave scratches or cloudiness, so do not assume that the toothpaste used on your teeth is suitable for the aligner. Ask your orthodontic team if product directions are unclear.
Do not soak aligners in mouthwash unless your clinician or manufacturer specifically approves it. Some coloured products can stain clear plastic. Do not put aligners in a dishwasher or leave them in a hot car. If an aligner looks warped, cracked, or no longer seats properly, do not force it into place; contact your orthodontist.
Should you brush your teeth before putting aligners back?
Yes, ideally clean your teeth after eating and before reinserting your aligners. The American Association of Orthodontists advises removing aligners for food and drinks other than water, storing them in their case, and brushing before they go back in. Food and sugary or acidic drinks trapped against teeth can increase the risk of decay and staining.
If you are away from a toothbrush, rinse your mouth with water and clean your teeth properly as soon as practical. Continue twice-daily fluoride toothbrushing and daily cleaning between teeth.

How often should aligners be cleaned?
Clean them every day and rinse them whenever you remove them. The frequency of a deeper soak depends on the product, wear schedule, and your orthodontist’s directions. A cleaner marketed for one brand may not be right for every appliance. Follow its contact time and rinse directions rather than leaving aligners in a solution indefinitely.
White buildup or persistent odour may reflect deposits or inadequate cleaning, but it is not a diagnosis. If the aligner remains cloudy or smells despite proper care, ask your orthodontic team whether to use a different approved cleaner or replace the tray. If your gums are sore, bleeding, or swollen, seek a dental assessment instead of only cleaning the appliance more aggressively.
Questions people ask
Can I clean clear aligners with toothpaste?
Do not use toothpaste unless the manufacturer or your orthodontist says it is suitable. Some formulations can scratch clear plastic. A soft brush with an approved cleaner is a safer default.
Can hot water make clear aligners fit badly?
Yes. Heat can warp clear plastic. Use cool or lukewarm water and ask your orthodontist about any aligner that suddenly feels loose, tight, or distorted.
What should I do if I dropped an aligner?
Rinse and clean it before reinserting it. If it fell into a toilet or another heavily contaminated place, contact your orthodontic team for advice rather than relying on a harsh household disinfectant.
