Dentures have their own drawbacks, but so much better than partials IMO. The bottom is the most problem, so if you can get by with just an upper, you should discuss that option with your dental provider.
Your gums will recede with time. An upper stays in place by creating a suction with the roof of your mouth. You will quickly learn to suck with your mouth closed, making that suction tight. It helps with the lower denture at first, but as the gums recede, the lower has nothing to hold it in place. That’s why I say if you can manage with only pulling the uppers, you are better doing that.
It is very important that you make sure you have the best possible professional to obtain dentures. Some are fine with extractions and fillings, but when it comes to dentures, there are various steps involved, and some just don’t have the necessary expertise. Measurements to ensure your bite lines up correctly, for instance. I walked out on one dentist because the “student” taking my impression had my upper lip tucked in, which would have been a disaster for the fit. I was pointing and grunting and I was told gruffly that I needed to hold still for the impression to “take”. She was holding the tray of goop in my mouth with one hand, and my head with the other. I finally had to physically shove her away.
This kind of thing is why I say if you can shop around, go online and Google perspective providers and see what feedback they get. If all the comments are about caps, fillings, and the appearance of the lobby, I would look elsewhere. Look for comments like good fit, and love my new smile.
One final thing, a very old, country dentist in a tiny town gave me this advice.
After extractions there will be bleeding. Take a clean, dry (never used) tea bag. Bite down on it, and keep it there for a few minutes. It will stop the bleeding, and help to ease the pain. I thought he was nuts, but I tried it. It worked. You don’t have to bite hard, just enough to hold it in place.
It has been several years since I had the partials. Maybe they make them better now, but I doubt it. If you have any people who have had partials in recent years, go more by what they say on that, than me.
Dentures, full or partial, are for a long time. They are important for eating, appearance, comfort, and speaking. You are right for finding whatever advice you can get.
