Hello,
Consult a dentist in your neighborhood for finding out the cause of the pain and to get relieved.I would not recommend over the counter medications for pain relief as it would only provide short term pain relief and the actual cause (it could be due to caries or apical periodontitis ,abscess ,impaction or maxillary sinusitis )has to be treated to achieve permanent cure .
Next Steps
visit a near by dentist for further management as early as possible
