Hi. There is always some reason behind a painful tooth which requires a careful diagnosis by a dentist and appropriate treatment. You should always trust the person who treats you. Don't keep on changing dentist just to come up with some easy get away. Get treated for a permanent solution. Pain killers just Mask the pain and they don't treat the cause.

Hai...why are you changing doctors...medicines will take time to heal...also painkillers alone won't create changes...need antibiotics too...also u should do salt water gargling and very important part is to get your teeth treated soon for permanent solution

It is not advisable to use pain killers for longer durations as this may cause other medical ailments.

U have said u met many doctors. May I know why u changed so many doctors. Did no doctor tell u abt Ur problem and treatment options for it. Pls get treatment done wht ever is necessary. No pain will disappear permanently jus by tablets. Also like u said, it is not really advisable to take painkillers for long time...
