Oral Surgery/postextraction infection


QUESTION: hello sir,
i am not understanding how it is happening...
in attempt to anesthise tooth (grade 3 mobility) i give many injection in pockets...the patient return with swelling pain and swalloing it can be prevented and where can be fault.....
is it necessary to prescribe antibiotics after extraction.....

ANSWER: Ritu -  if you are unable to anesthetize and you are sure that the injection is done in the correct site and the inferior alveolar nerve has been anesthetized, then only inflammation of the nerve can be the cause.  In that situation you need to attempt to reduce inflammation.  The simplest and very successful technique is to simply have the patient begin warm salt water rinses in the exact area for about 2-3 minutes, 4-5 times a day.  

If the inflammation exists after the extraction, and there is some inflammatory bleeding after the extraction, then antibiotics would be appropriate.

QUESTION: I prescribed the antibiotic to that patient...amox,clav combination and serratio, day patient come with yeavy pus discharge from socket...does my intraligamentary injection done this!!!

Ritu -  It is difficult for me to know why, but this to occur the next day should have nothing to do with the antibiotic.  I again suggest that the patient immediately begin warm salt water rinses for 3-5 mintutes, 4-5 times a day.  I cannot tell you if the injection did this, but you may have introduced bacteria into the ligamental attachment with the injection.  Have the patient do the above rinses immediately.
