Gum wasting and teeth falling out is one of the advanced symptoms of scurvy. However, judging from the number of people who have bleeding when toothbrushing, there is a lot of sub-clinical scurvy in this and any country. Our doctors are not really taught much about this whole subclinical vitamin/mineral deficiency issue. The drug companies are too busy running around giving away free samples and urging young doctors to try their drugs. Many years ago when I was working in the Pharmacology Dept. of a major medical school, my job was formatting and typing the 78 page laboratory manual for the students. There was one page about deficiency diseases with scurvy, pellagra a beriberi. No mention at all of sub-clinical deficiency issues in health.
