Re: Getting a temporary partial denture...need advice please
"How long can I feasibly wear them? "
6 months or less for them to still fit. The true reason for a flipper is as a temporary during bone healing either after extractions or implants (both which take 3-6 months).
The exact fit depends entirely on which teeth you have left, what relationship they are in, and how much bone you have. They may fit well in the beginning, but over a few months the acrylic tends to warp without metal support. I don't want to discourage you, you have a great attitude about the whole situation! I just want you to keep your expectations realistic.
"Can I eat with them in?"
While technically you can, they are called flippers for a reason, they flip in and out. With the amount of pressure used to eat, they will not be very stable at all. Flippers are almost exclusively for esthetic use only.
Permanent partials use a metal framework (exception valplast) that has clasps which grab hold of natural teeth to give it support for function during eating.
"What's the best method for cleaning them?"
Any denture cleaner. Avoid toothbrush/paste, they will damage the acrylic.
