You should always start by rinsing your Invisalign aligners with lukewarm water. Using water that’s too hot can damage them. You should also only use a soft-bristled toothbrush to gently brush them (make sure you brush your teeth before putting them back in too!)

Alternatively, you can also soak them in any retainer or denture cleaners by following the product instructions. There are specific Invisalign cleaning systems on the market too.

Don’t put your Invisalign aligners back in if your teeth are not cleaned. Food debris that is stuck between your teeth can discolour your aligners and cause calcium and bacteria buildup.
