If you were positive one week, I would suggest you to postpone the treatment as you may be tested negative but you may still be seropositive and can act as an asymptomatic carrier. It is advisable to use a course of antibiotics. If the pain is unbearable and emergency then your dentist will do the extraction taking all the safety measures. Some patients are also using steroids and blood thinners. If you did pls inform your dentist.
Next Steps
Use a course of antibiotics and delay treatment for 2-3 weeks
Health Tips
