Aligning your teeth with Invisalign is exciting, and your results depend on wearing your trays consistently and keeping them clean. Because clear aligners are removable, caring for them is simple, but proper hygiene is essential to prevent staining, odour, and bacterial buildup. Here are seven easy tips to help you keep your aligners fresh every day.
1. Rinse with Lukewarm Water
Rinse your aligners with lukewarm water each time you remove them. Hot water can warp the plastic, while cold water may not effectively loosen debris. Rinsing keeps the trays moist, reduces cracking, and helps remove saliva and buildup. When brushing them, always use a soft-bristled brush to avoid scratches.
2. Soak Your Aligners: Consider Specialized Cleaning Crystals or Tablets
Soaking your clear aligners daily in Invisalign cleaning crystals or other dentist-approved tablets helps dissolve bacteria and keep your trays clear. This method is gentle, effective, and ideal for long-term clear aligner care.
3. Use Baking Soda for Occasional Deep Cleaning
If you notice discoloration, scrub gently with a paste of baking soda and water. Rinse thoroughly before wearing them again.
4. Avoid Mouthwash, Especially Colored Rinses
Never soak aligners in mouthwash. Many mouthwashes contain dyes that will stain clear aligners, leaving them tinted green or blue. The alcohol content can also damage the plastic.
5. Brush and Floss Before Putting Aligners Back In
Good oral hygiene helps protect your teeth and prevents food particles from becoming trapped under the trays. This simple habit keeps both your smile and your aligners clean.
6. Always Store Aligners in Their Case
Whenever you’re eating or drinking (anything besides water), place your aligners in their protective case. This prevents loss, cracking, and exposure to germs.
7. Handle Your Aligners With Clean Hands
Wash your hands before removing or inserting your trays to keep harmful bacteria from transferring to your mouth.
