First of all let me suggest you that ,to get a proper treatment you should trust on your dentist
Or else you can go for second opinion
Usually antibiotics has to be taken in complete course ,prior to extraction of wisdom teeth which is inflamed.
Avoid anxiety and stress as it can worsen the condition.
Gargle using warm saline and betadine
Maintain oral hygiene
Please have an open discussion with your dentist regarding this.
Hope this helps.
