How does the dentist should clean your dentures?

My grandma went to her anual dentist appointment, she has a full prosthetic denture on the bottom of her mouth, usually when she goes there for a check up the "dentist helper" takes the whole denture out and cleans the dentures and then they clean her mouth and check for sores and things like that, last time she went to the dentist the lady who cleaned her dentures didn't remove the dentures from her mouth and cleaned the dentures while on my grnadma's mouth, she told her that it is not necessary to take them off every time. So her question is, has anyone experienced this? is it ok to clean her dentures while still on? should they take them completely off to clean them? this happens only when she goes to the dentist, other than that she does it herself every day, she takes them off and cleans them at night. Any advise would be greatly appreciate it.

I would not agree with this approach. Sure, you can clean the parts you can get to without taking them out of the mouth, but you can't clean the bottom. If you are going to do it - do it right. However, it is not the dentist or hygienist's obligation to clean the denture. Personally, we DO this in my office, but not everyone does.

The bigger issue here is that it is not possible to examine the gums under the denture without removing the denture. A soft tissue examination should be part of every dental check up. Seriously.

It is not the job of the Dentist to clean the dentures. In my opinion it has to be cleaned daily, by us. That's what my Dentist, advised.

I am not sure if the dental assistant said that it is not necessary for THEM to take it out when she sees them, or what to do at home. If your grandmother is taking them out every day and brushing them outside and inside at night, then tell her she is doing the right thing. You can still get bacteria and tartar build up on your dentures, not just your natural teeth, so it is important to clean them thoroughly. If the bacteria gets on the gum tissue, it can still get infected. She should also take them out at night so that her mouth can "breathe".

In between meals it is ok to brush the denture still in the mouth and remove any food stuck to the denture, but if she feels any food has gotten underneath the denture, then yes she will need to take them out and clean underneath it.
