Toothaches and gum diseases are usually only related in that they both occur in the mouth. They have, generally speaking, very different causes and therefore will be discussed separately in this article. The classic toothache is almost always caused by nerve pain due to an exposed nerve root. While it is true that receding gums can expose nerve roots, causing “tooth” pain, another scenario is that of a filling worn down or fallen out. Chewing gum regularly will make fillings come out more quickly; avoid it if possible. Usually a toothache requires a trip to the dentist, however there a number of treatments you can access relatively easily if you can’t see the dentist right away.
