Can I continue to feel pain even after dental treatment?

Can I continue to feel pain even after dental treatment?

I had inlay and resin treatment a week ago.

Since then, it feels slightly uncomfortable when chewing with that tooth, so I just assumed it was because I got treatment.

I did it, and since then I haven't really been conscious of it, so I didn't know.

Suddenly, at some point, I had some pain, I wasn't sure if it was my teeth or my gums.

Now that time has passed, I feel like I'm okay, too.

Is this possible? It has been about a week since I received dental treatment.

I'm wondering if I should go back to the hospital... but then again, I've been perfectly fine for two whole days, so I can't really do that...

Could this be a temporary phenomenon?
