Frequent inflammation occurring inside a prosthetic tooth

Since my teeth are inherently weak...

There are many things I haven't done yetㅠ

Since early twenties.

Inside this prepared area...

So, I always get inflammation on the palate just inside my teeth, and it often causes me stress.

This won't get better in just a day or two.

I always use Listerine, but...

It’s uncomfortable, so I keep touching it with my hand;;

I didn't know the reason before..

Upon careful reflection...

They are teeth with crowns on them.

These days, even after getting implants, it still seems to happen occasionally.

Will this also almost disappear if the immune system improves?

Is there a way to reduce inflammation quickly?

Will this also almost disappear if the immune system improves?

No matter what I eat, I really don't gain weight, and it's because I'm so short;;;
