Watch ya mouth man !

I am a man cursed ! I'm having real problems with my mouth . My gums are sore , my dentist says its caused by a build up of tarter ?  What causes it ? He says no one knows . The only thing I know is that this keeps returning each week even after using proper mouth wash ( not the type thats supposed to make you more attractive to the opposite sex ) thats anti-bacterial . The relief is fast on using this , but so is the return . The soreness even enters my nasal passages its that bad .
  Eating meat aggrivates it the most as the texture rubs on my gums . So thats being cut down to a minimum and I dont care as im at the stage I just want to feel my mouth is at ease . There is nothing worse than having trouble eating at Christmas !
