Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.
Call emergency services for trouble breathing or swallowing, rapidly spreading swelling, or signs of a severe allergic reaction.
These are emergency symptoms, not routine follow-up concerns.
Contact your dental team promptly if pain is worsening, the inlay feels high when you bite, or sensitivity is not settling.
Also call if the inlay chips, moves, or comes out.
Keep a loose inlay in a clean container; do not glue it back yourself.
Seek urgent dental or medical care for increasing facial swelling, fever with dental pain, pus, or difficulty opening your mouth.
Every sign above is quoted from the sofidex article on Porcelain inlay. If you are not sure, err upward — it is always reasonable to be checked.
