Thanks for contacting healthcare magic.
First you mention that there is
tooth infection is present. Because of long sranding tooth infection there is facial space infection may rule out.
You have generalize swelling over body that is not because of that tooth infection.
Generalize swelling over body called
anasarca.
There are many cause for body swelling. Abnormal kidney function may cause ankle swelling more.
So Do kidney function test.Water retention may cause this type of swelling.
Heart problem may cause this type of symptoms.
Any
allergy may cause sudden
anaphylaxis reaction. That also cause sudden swelling in body part.
In
diabetes more chanses of infection so....it may cause severe infection condition.
Check your blood sugar level.
Liver problem may cause this type of symptoms.
So still liver function test can done for further diagnosis.
Wish you a good health.
Take care.
