I am having severe toothache after losing silver filling from a tooth (? bicuspid) 5th from the middle.  The dentist palpated gum tenderness along the jawline below the affected tooth.  The dentist filled the tooth with white filling and instructed me to take doxycycline for 8 days and mefenamic acid every 6 hours for persistent toothache.  I noticed as soon as I left the dental clinic that there was slight numbness along my jawline and lower lip on that side where I had the filling.  Could this be due to 1 tab mefenamic acid and 1 tab naproxen I had taken 4 hours before going to the dentist?  I am worried about the numbness and gum tenderness.  The dentist did not tell me what was causing the persistent toothache as well.
Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, as you have toothache after filling don't worry you again visit your dentist if your toothache continues for more than three days.  Toothache can be due to exposure of pulp, due to which still you have pain after filling. Numbness can be due to Anesthesia if your dentist has given you or due to medication you are taking.  Do warm saline gargle two - three times a day.  Hope this will help you.  Wishing you good health.
