dear friend.
thanks for sharing your concern.
abscess is an infection consisting of loads of bacteria,pus and debris.it cause swelling,
redness,pus,pain,raised body temperature etc.
your doctor has prescribed antibiotics to reduce this infection.
now the general principle of any abscess is that it should be drained first,followed by antibiotics.
i would suggest you to see your
dentist as soon as possible.please do not be apprehensive about dental treatment.
now a days painless dental treatment is done by using an
anesthetic.
therefore just visit your dentist and get an x ray done,after that your abscess can be drained well and the affected tooth can be saved by RCT.
meanwhile take your medicines properly without any gaps,and follow very good
oral hygiene.
hope it helps
