Since you have undergone extraction of wisdom tooth which is usually a traumatic procedure,the stress undergone can cause chest pain
I would advice you to take complete rest for a minimum period of 5-6 days.
Gargle frequently using warm saline or betadine
Maintain oral hygiene
Take complete course of antibiotics-analgesics prescribed.
Avoid anxiety and stress.
Dressing the socket using gauze soaked in povidine iodine solution can enhance wound healing
If symptoms persists,please do visit a physician.
Hope this helps.
