Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain and presentation of symptoms it is very much clear that you have infection in the gums post surgery and the yellow discharge is Pus..
You should immediately consult your treating dental surgeon and get evaluated and the
dentist will do the necessary treatment like irrigation and prescribe you with broad spectrum antibiotics like
Augmentin 875 mg for clearing the infection..
You need not to worry as the infection is treatable and can be taken care of very well and if treated early all will go well and you will not loose your jaw at all..
As you are a smoke you should completely stop
smoking at least till you are healed completely because smoking delays healing as well as cause Inflammation of the healing tissues which can make them more prone to infection..
Hope this information helps..
