Can I clean Invisalign with a toothbrush?

Yes — Align Technology’s official Use & Care instructions say you may clean active Invisalign aligners with a soft‑bristle toothbrush, water and a small amount of toothpaste, then rinse thoroughly before reinserting them. [1]

Quick takeaways

• Align Technology’s official instructions permit cleaning active Invisalign aligners with a soft‑bristle toothbrush, water and a small amount of toothpaste (then rinse).
• Avoid denture cleaners or soaking aligners in mouthwash — the IFU warns these can damage the aligner surface/finish.
• Some clinicians and patient resources prefer plain water, mild soap or approved soaking products to reduce long‑term clouding or scratching concerns. [1, 2]

What the manufacturer says

Align Technology’s Use & Care for active Invisalign aligners explicitly instructs: “Clean your aligners prior to each insertion. Use a soft bristle toothbrush with water and a small amount of toothpaste.” It also instructs you to rinse thoroughly after cleaning and warns against using denture cleaners or soaking aligners in mouthwash because those products can damage the aligner surface or finish. [1]

Practical nuance and alternatives

Although the IFU permits a soft‑bristle brush plus a small amount of toothpaste, Align Technology’s cleaning product documentation also describes an approved soaking option (Invisalign Cleaning Crystals) for periodic cleaning. That FAQ does not contradict the toothbrush method but shows there are multiple allowed cleaning approaches. [2]

Many clinicians and patient resources suggest using plain water, a gentle unscented soap, or designated cleaning solutions for routine care because some toothpastes or abrasive brushing can make aligners look cloudy or scratched over time. This is a practical caution based on material considerations; it does not override the manufacturer’s IFU which still lists the toothbrush method as acceptable. [1, 2]

If you don’t have a toothbrush or cleaning system

The IFU provides fallback guidance: if you can’t brush immediately, rinse your aligners under running water and clean them as soon as feasible. For periodic deeper cleaning, Align’s FAQ describes using the approved cleaning crystals diluted in water for soaking. [1, 2]

How Smilo can help

If you want to build a consistent cleaning habit, Smilo can log your aligner cleaning sessions and set configurable regular‑clean and deep‑clean reminders so you remember to clean before reinserting and to use a soaking cycle when appropriate.
