To a degree
Partial dentures are foreign objects.
As such i would not necessary call them "comfy". However, many patients accommodate just fine to them. Certainly there can be an absence of pain and discomfort. It may not be unfair to compare to contact lenses. I have worn contact lenses for over 30 years. While they may be free from pain and discomfort most of the time, i wouldn't consider them "comfy".
