For about 8 months now my smell has changed. Everything smells like wet/dirty dog. I do have an abcess in the root channel of one of my teeth. The dentist has given me courses of anti-biotics, which clears it for a while then the abcess re occurs, root channel treatments have also not helped. I will have to have the nerve cut out where the infection keeps re occurring. The bad smells are the worst though, could this be caused from the infection?
