Dental health issues are among the most prevalent health afflictions facing Americans. Nearly half of Americans have gum disease. Ninety percent have had at least one cavity, and about 1 in 4 have untreated cavities. Untreated oral health issues can lead to serious health problems, including cardiovascular disease. This means that dentists are on the front lines of the fight for better public health, and oral surgery does a lot more than produce a pretty smile.
