WHO/Godfrey Xuereb. Obesity has reached epidemic proportions globally, with at least 2.8 million people dying each year as a result of being overweight or obese. Once associated with high-income countries, obesity is now also prevalent in low- and middle-income countries.
Well the same goes for you teeth. An Orthodontist is specialized just in braces and such. A general dentist is more for fillings, extractions, cleanings, crowns, etc.
