Hi mam... Tooth ache ay be due to cavitation or wisdom teeth ...    In case of cavitation, the infection spreads periapically and cause swellimg of gums and cheeks..   Both clinical and radiographic examination is necessary to rule out the cause.... Get x_ray (IOPA) of the involved tooth to rule out the cause... If the swelling is due to cavitation you nee to undergo Root canal treatment... If the swelling is due to wisdom teeth you need to undergo surgical removal of wisdom teeth ..

Hello mam, tooth ache cannot come only from infection or decay,it can because of your wisdom tooth also, so always examin your teeth properly if you have a pain on decay teeth then you should visit your dentist...

You should consult to dentist. Only medicine taken is not okay. You need of treatment of this tooth.

You need to consult a dentist who will treat the infected tooth. Taking antibiotics may only suppress the pain for a few days
