Good morning,
I only had 3 remaining teeth to be extracted on the bottom. These remaining teeth were removed prior to the partial being placed. All of the other teeth had been removed for many years, and as such, the bottom partial was quite straightforward. Since most of the healing had been established years ago.
With only 3 recent extraction sites left to heal, the bottom partial always fitting quite well. I did, however, use cushion grip on it until my gums toughened up from denture usage. I now use the lower without adhesive and without cushion grip. It could fit better, but it is usable in the current state. I'm due to return to the dentist for my permanent dentures soon anyway.
My full upper was placed immediately after the final 6 (front teeth) were removed. This was very painful after the anaesthetic wore off. Eating was difficult as things were painful and swollen. I will be totally honest with you here - these front teeth were more difficult to extract than molars. Especially the canines. These teeth are very strongly rooted. Well, in my case. This may differ per individual.
When your dentures start to feel loose due to healing, I highly recommend giving cushion grip a try (or similar products) this fills the gaps and has the denture fitting snug. I must admit, it's a little bit of trial and error to get it right. But when you do, it's an excellent product. Which snugs up your loose dentures and cushions your gums.
This cushion is very nice in the beginning when things are still healing and changing. Your gums will be sensitive for some time and I found the cushioning very advantageous. It really changed the game for me, particularly while eating.
