Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain swelling in jaw,lip and the area underneath the chin after extraction of teeth can occur most probably due to
allergic reaction to either the local anaesthesia injection or can be due to allergic reaction to any medication..
In case if it is due to anaesthsia then it will subside in 2 to 3 days as the effect of anaesthesia will wean off..
In case if still it does not improve consult your treating
dentist and get evaluated..
As of now do
cold compresses over the swollen areas..
You can take antihistamines like
Benadryl..
In case of excessive swelling due to inflammation
steroid injection can be taken for faster resolution of swelling..
Hope this information helps..
Thanks and regards..
