If there is severe pain beacause of the infection and swelling..my advice is take a radiograph (periapical xray).. then prescribe you antibiotics until the pain and swelling of the gums subsided..
Next Steps
After taking antibiotics and the pain and swelling are gone..remove the cause or extract the tooth..then observe for further improvement..
Health Tips
You have to visit your dentist every 4-6 months to monitor your oral health status and improve oral hygiene..
