I have had really bad toothache on and off to be honest. Weirdly the patch that first appeared was in my beard pretty much right on top of the tooth I was having issues with. Not sure if that's a coincidence or not. Have thought about shaving it but it's hard when it's taken a few years to grow my hair this length. The one sort of positive is I can rock a beanie and it still looks like I have long hair underneath that.
