Just to give you a heads up, you're going to have a number of these experiences, such as sores, sore spots, pinching,...so it's always important to check in with your dentist so they can adjust them. Funny thing with our mouths, the teeniest little thing out of place can feel huge!
I'm still getting sore spots, and I think that as long as we're alive and our bones and gum ridge line continue to change, we'll be getting modifications.
So you're normal, what you're experiencing is normal, make sure to take your dentures out to soak them, let your gums heal and not trap bacteria in your mouth. Tend to sore spots early.
See? You're starting to adjust already. Things get better. For real!
