Normal.

So ?

In a nutshell, there is inflammation of the supporting bone
and periodontal ligament. This is completely normal.

Patient: "Hey doc, it hurts when I do my arm like this !"

There are other structures that support the tooth; namely
the periodontal ligament and the lamina dura of the alveolus
<bony support>.
They still have innervation. Just a bit sore right now, eh ?
Yes, it takes a bit of time for inflammation to subside.

>noticable. Is this normal?
Completely normal and should subside within just a few days.
