Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
As per your complain and presentation of symptoms it seems that you are suffering from
DENTAL ABSCESS which has occurred due to deeply infected tooth and when the infection progresses from the tooth via root canals to the area below root tips there is pus formation and formation of dental abscess..
At times the pus perforates the bone and get accumulated in the soft tissues leading to swelling and pain..
You should take higher antibiotics like
AUGMENTIN 625 mg [
Amoxicillin 500 mg +
Clavulanic acid 125 mg] thrice a day and in place of tylenol you should take a higher painkiller that can control
severe pain like
TRAMADOL 50 mg thrice a day..
Do cold compresses over the swelling..
As some swelling and pain improves you should consult back your endodontist who can perform
Root Canal Treatment in which a hole will be made in the tooth and an escape way will be created for pus drainage so pus will get drained out and the infection will subside faster..
Once pain and infection will resolve the filling of the root canals and the tooth can be done..
Hope this information helps..
Thanks and regards..
