hello,
we are here to help you out.
the infection after extraction is suggestive of incomplete
wound healing due to dislodgement of blood clot.
As there are more chances of having infection to the wound in mouth because of presence of lots of bacterias in oral cavity. So you have been giving antibiotics.
also the surgical removal of wisdom tooth is accompanied with the removal of bone along with it which takes time to heal.
But it has been long time after extraction so I would suggest to have x-ray done,and check up for any remaining tooth part or infection to bone. You should visit the oral surgeon for this.The thorough examination and modification in the treatment by specialist is must to avoid further inconvenience.
for
home care :
1)you should keep mouth as clean as possible.
2)If you are smoker stop
smoking instantly at least upto the healing is complete.
3)use Chlorhex mouthwash-gargle 3-4 times a day
or you can gargle with luke warm water add 2 teaspoonful of salt in 1 full glass of water.
4) Avoid spicy food
5) Take protein rich diet and fruit juices.
Hope the information provided is helpful to you.
take care.
