I went a year without any teeth, to do 4 upper,4 lower implants, for a set of bars that mine clip to. I did have a temporary set, but the lowers didn't fit, and I couldn't eat with them, so basically, I wore the upper one so I didn't scare little kids.
When they were finished, they were great. I could eat anything. But after a couple broken teeth, I stopped eating apples or corn without cutting. But to your original question;
Pro- A broken tooth will never hurt.
Con- A grain of salt or hard crumb, caught under the denture can cause a raw spot that can make eating painful for days.
