Mouthwashes `can Raise risk of Heart attack and strokes`: Antiseptic gargles also kill Good bacteria

Sharp edge: Mouthwash Corsodyl can lower blood pressure

Using mouthwash is a ‘disaster’ for health, increasing the risk of heart attacks and strokes, scientists are warning.

Swilling kills off ‘good’ bacteria that help blood vessels relax – so increasing blood pressure.

When healthy volunteers used Corsodyl, a brand containing a powerful antiseptic, their blood pressure rose within hours.

Professor Amrita Ahluwalia, who led the study, last night condemned the widespread use of antiseptic mouthwash.

She said: ‘Killing off all these bugs each day is a disaster, when small rises in blood pressure have significant impact on morbidity and mortality from heart disease and stroke.’

More than half of British adults regularly use mouthwash, creating a market worth £180 million a year.

The study compared blood pressure levels in 19 healthy volunteers who started using Corsodyl twice daily. Their blood pressure rose by between 2 and 3.5 units (mmgh).

This effect ‘appeared within one day’ of using the mouthwash, researchers wrote in the journal Free Radical Biology And Medicine.

For each two-point rise in blood pressure, the risk of dying from heart disease rises by seven per cent, according to separate research. Such a rise also increases the risk of dying from stroke by ten per cent.

Heart disease and stroke are the biggest killer in Britain.

Prof Ahluwalia, from Queen Mary University of London, said: ‘We are not telling people to stop using antiseptic mouthwashes if they have a gum or tooth infection – but we would ask why anyone else would want to.’

Corsodyl contains 0.2 per cent by volume of the antiseptic chlorhexidine. Other antiseptic mouthwashes made by Boots and Superdrug contain the chemical in the same concentration.
It kills microbes needed to help create nitrite, essential for blood vessels to dilate properly. But the mouthwash caused nitrite production in the mouth to fall by over 90 per cent, and  blood nitrite to fall by 25 per cent.
