If you are having pain, you may need to be seen by your dentist immediately. You may need a root canal, extraction, or medication to relieve the pain. Sometimes, with major swelling, you may be asked to take the antibiotic prior to the dental procedure.
Some Emergency Dental Procedures
- Root Canal
- Broken filling in the esthetic zone
- Extraction
- Abscess or Swelling
- Pain medication
The most dentist takes to make the schedule available so they can take you as a walk-in in such an emergency situation.
