Men have been advised that having stains on their teeth could be prematurely aging them.
According to Models Direct, as teeth age they naturally discolour, but habits like smoking and drinking lots of coffee can speed up this process.
"Our teeth lose their pearly white colour as we age, so whiter teeth will make you appear younger … Just make sure they’re not so white that they look unnatural!" the agency stated.
The American Dentists Association recently noted people could improve their confidence by undergoing teeth whitening treatments to give themselves a more dazzling smile.
The association stated take home kits can be useful, but for a more permanent, professional finish, people are advised to visit their dentists to carry out the procedure.
