“Can u sleep in your partial dentures?”

Hello, You can sleep in them, but it is best not to - you want to allow the tissues to breathe and also for the partials to be soaked overnight in a cleaning solution.

It is best not to sleep in your partials. This gives your teeth, gums , and other supporting structures a chance to rest too,

I guess the question is really not "Can you sleep in your partials", but "Should you sleep in your partials?". And the answer would be no. You shouldn't sleep in your partials. Your gum tissues under your partials need to be able to get "air". Leaving your partials in over night can lead to a yeast infection under the partial, inflammation due to debris and bacteria being trapped under them, and can also sometimes be a choking hazard. As a dentist, I can always immediately tell when my patient's are sleeping in their partials because their mouth will have an area of inflamed red gum tissue that is the perfect match to the shape of their partial denture.

Yes but clean the teeth thoroughly before putting the partial back in the moutn.

The answer for the overwhelming majority of patients is no. Plaque can be trapped under your partial, leading to increased decay and periodontal disease. Every patient is unique, so check with the dentist that is treating you.
