Remove Invisalign aligners to eat or drink; food particles can build up and damage them, despite some drink allowances.
Using hot water to disinfect aligners can damage them, so it's recommended to use warm water for cleaning instead.
Smoking with Invisalign is not recommended, as it stains the trays and can cause tooth decay due to trapped nicotine and tobacco.
To prevent bacteria buildup and protect aligners from germs, store them in airtight containers when not in use.
