Indeed, findings from the 2013 Global Burden of Disease Study show that untreated caries (decay) is the most prevalent and severe periodontal (gum) disease, the sixth most common disease in the world.

Pain, infection, and difficulties eating and speaking are all common consequences of oral disease.
