Two sitting rootcanal

This is simple case and after doing rcf i felt that filling is short and immediately removed 
gp points and called pt on next day and did filling in fresh mood. Pt was alright didn't took any medicine. The pain which he had was because of site of injection and keeping mouth open for longer period. Because of good endo most of my pt doesnot take any medicine . hardly they r taking one or two painkillers to relieve pain., which i told pt to take it compulsery at least one painkiller for safer side.I donot prescribe antibiotic which i was doing few years back.Now the role of medicine has reduced a lot. If any pt comes with acute pain and if i do endo he get relief immediately and the no of medicine also go down.
