Is it normal to have a gap between crown and gums in three-tooth PFM bridge? (Photo)

Hello
In many cases it depends on the dental structure, but it is not a cause for concern; it is possible to have a good oral hygiene to avoid future complications
Regards.

A small gap is  normal and indeed essential to allow you to clean around and under your bridge and maintain good oral hygiene around the bridge. Ideally you should have been shown how to do this using Interspace brushes and Super floss.

Hello

Its normal has a space between the gum and Crown. You need take care of that area; keep clean, use floss and interdental brush tooth. But that’s normal.
