If dentures dry out, they will become hard and difficult to clean.
They can more easily crack or warp.
It will be easier for the gums underneath your teeth to become irritated.
So, it is important to keep your teeth moist by soaking them in water or a denture-soaking solution when they are not being worn. Soaking solutions can help reduce bacteria growth and keep things from drying out.
Many different types of soaking solutions are available, so be sure to ask your dentist which one is right for you.
