You sit in the dentists chair, look up at the bright white light and get the same old question for the umpteenth time: do you floss? (And no, were not talking about the dance ).

An investigation by Associated Press (AP) in 2016 found there was little scientific evidence to suggest flossing is beneficial despite it being recommended across the board, from dentists as well as the NHS .

Four years after APs findings, which saw the US government quietly update its guidelines to remove recommendations to floss on its website, UK dentists are standing by what they said: flossing, or using interdental brushes , daily is good for our teeth.

Specialist orthodontist and member of the British Dental Association, Dr Iain Hoeltschi , tells HuffPost UK: Even though there has been conflicting evidence about flossing and its effectiveness, I still thoroughly recommend flossing once a day. I also recommend using interdental brushes as these are better equipped to remove food particles and bacteria that can build up between teeth.
