I had "soft" teeth from a very young age, inherited from both parents, & spent lots of time every year getting the range of dental care, even tho I was in a group of kids who had "experimental" pioneering fluoride treatments. The whole range, drilled, filled, root canals, crowns & finally extractions. Got the last of them out over 10 years ago & had a "denturist" make the new ones. He did very well, fine tuning till perfect. Very expensive but they lasted that long with good care on my part. Finally early last Dec I bit into a hard pizza crust & the upper broke right down the middle. The lower is still perfect, never any trouble there. Am still in the process of getting it replaced, have a temporary while they are working on the new upper. Also very expensive, but it will be very good I'm sure. I was very very glad I did it & still am, but think the secret is having a denturist who will work with you patiently until it feels perfect.
I know nothing about dentures with implants & frankly the idea of having screws put into my jaw bones through my gums creeps me out. Ick
