Third molar tooth is relatively tough one to extract and the trauma is relatively more compared to normal tooth extraction. It is advised to continue medicines and wait for 2-3 days.
Next Steps
Ask your dentist for some topical gel or Becosule-Z capsules ( If required). Ulcers will go on their own in few days.
