Around two-fifths of Brits do not go for regular dental check-ups, according to a new study, meaning that they could be in need of treatment such as bridges and crowns and not know.
Figures from the NHS Information Centre highlighted that 61 per cent of the UK population go to get their teeth checked out regularly, while ten per cent only to go the dentist occasionally and 27 per cent only visit when they have trouble with their teeth.
However, the proportion of people who visit the dentist did rise between 1978 and 2009.
People's dental health also improved, with 71 per cent of adults having no decay on the crowns of their teeth, while over 80 per cent of people across England, Wales and Northern Ireland have the accepted number of teeth required to eat without problems.
NHS Information Centre chief executive Tim Straughan said: "This survey shows dental health has improved in England, Wales and Northern Ireland and the condition of people's teeth overall has got much better since this survey was first carried out (in 1968)."
Last month, a study published by the NHS Dental Epidemiology Programme found that dental health among children is improving, with the percentage of 12-year-old children affected by tooth decay dropping from 37 per cent in 2001 to 33 per cent in 2009.
