Researchers have found that people who are missing some of their pearly whites are up to a third more likely never to have a good old-fashioned chortle.
People who are missing some of their teeth whites are less likely to laughLosing your teeth really is no laughing matter, a study suggests.
Previous research has found that older people laugh less and the researchers looked at whether loss of teeth was a factor. When the researchers matched that with tooth loss, they found that compared with people who had 20 to 32 teeth, those who had nine or fewer - and did not wear dentures - were 30 per cent more likely not to laugh. Among those with 10 to 20 teeth and no dentures, the risk was 14 per cent higher.It leads to less exercising of the chewing - or masticatory - muscles, ultimately making them weaker.
