One in five give teeth cleaning the brush-off at the weekend: A fifth of Britons admit shunning the hygiene practice on Saturdays and Sundays 

• The revolting fact was revealed in a survey of the nation’s oral health 
• Nearly 40 per cent of ‘non-brushers’ said they ‘couldn’t be bothered’

Weekends are a time for taking it easy. 

But it seems some Britons may be taking relaxation too far – one in five admit they are so laidback they don’t brush their teeth on Saturdays and Sundays.

The revolting fact was revealed in a survey of the nation’s oral health.

One in four blamed hangovers, while more than a quarter said they only brush their teeth at the weekend if they have to leave the house.

Nearly 40 per cent of ‘weekend non-brushers’ said they just ‘couldn’t be bothered’, revealed the study of 2,000 adults by GlaxoSmithKline.

More than one in five also claimed that they couldn’t remember the last time they changed their toothbrush, while six per cent admitted that they have used fizzy drinks or alcohol to rinse out their mouth after brushing.

Some 27 per cent said they only brushed for a minute or less – half the recommended time.
