The majority of toothbrushes contain
evidence of faecal matter and harbour dangerous bacteria, new research
has found.
A study conducted in Quinnipiac
University found that 60pc of toothbrushes contain traces of faeces and
have the potential to harbour dangerous bacteria such as staphylococcus
aureus which is the cause of MRSA.
Toothbrushes which sit side-by-side at the edge of the sink can also be harbourers of the herpes virus.
The
research found that faeces found on toothbrushes often was not that of
its owner, after the scientists analysed the tooth brushes in the
communal bathrooms of Quinnipiac University.
The
study was lead by Lauren Aber of Quinnipiac University who analysed
toothbrushes in the communal bathrooms within the college, used by nine
people each.
“The main concern is
not with the presence of your own fecal matter on your toothbrush, but
rather when a toothbrush is contaminated with fecal matter from someone
else, which contains bacteria, viruses or parasites that are not part of
your normal flora,” she said.
“Using
a toothbrush cover does not protect a toothbrush from bacterial growth,
but actually creates an environment where bacteria are better suited to
grow by keeping the bristles moist and not allowing the head of the
toothbrush to dry out between uses,” Aber said.
Meanwhile
a recent study revealed that 24pc of Irish adults skip brushing their
teeth at least one morning a week despite the fact that it is an
important part of self-confidence for most of us.
The
research carried out by Oral B revealed that 75pc of Irish people are
wary of bad breath should they happen to doss on brushing, while 22pc
would be reluctant to smile.
Perhaps
even more disgusting than the lack of teeth brushing is the fact that
one in three Irish adults has shared a tooth brush with a friend or
relative.
