This explains a lot..
LONDON (Reuters) - More than 60 percent of Britons use items such as screwdrivers, scissors and earrings to remove food from between their teeth, according to a survey published Friday.
The National Dental Survey found that, when it came to oral hygiene, people used whatever was close to hand to pick their teeth.
More than 60 percent questioned by the British Dental Health Foundation said they used makeshift items, including knives, keys, needles and forks.
The survey also found that 23 percent of people chose to leave food stuck between their teeth, increasing the risk of gum disease and bad breath, according to the foundation which promotes oral health.
