Immediate Dentures Advice

I'm about 18 days post extraction, with immediates. I've had two adjustments because of sores and pain.

My last appointment they filed the sore spots down and also filed down the teeth on my bottom right side cause the said the bite was off. And they made it known that my bite wasn't corrected when they made scans before my denture was made. Is this normal or should it have been corrected?

Feel like my tops are too big. I feel like my teeth don't line up, may just be me otherthinking it. Both the top and bottoms teeter to the front, they touch in the back, but my front gums don't fill or touch the inside of denture. Dentist said just to use poligrip, but feels uneven when I do.

Told me I'm not due for a Reline until middle of August. But both top and bottom fall out without adhesive.

Anyone dealing with the same thing? Or any advice? Thank you!
