Is a tooth infection serious?

I tend to have weak teeth genetically, so I often have to visit the dentistㅠㅠ

I'm still in my 30s, and I already have several crowned teeth...

Lately, I think I keep developing symptoms of rhinitis because I've been under a lot of stress.

It turns out that the inflammation in the tooth was the cause.

Do dental inflammation symptoms last a long time? Once it occurs, is it chronic?

I heard that once you get odontogenic suppurative inflammation, it can become chronic.

Is it really true?ㅠㅠ
