A new research has found that coconut oil attacks the bacteria behind tooth decay and could be used in dental care products.

Scientists found that coconut oil which had been treated with enzymes stopped the growth of Streptococcus bacteria – a major cause of tooth decay.

Tooth decay affects 60% to 90% of children in industrialized countries.

Speaking at the Society for General Microbiology’s conference, the Irish researchers say that coconut oil also attacks the yeast which causes thrush.

The research team from the Athlone Institute of Technology in Ireland tested the impact of coconut oil, vegetable oil and olive oil in their natural states and when treated with enzymes, in a process similar to digestion.

The oils were then tested against Streptococcus bacteria which are common inhabitants of the mouth.

Only the enzyme-modified coconut oil showed an ability to inhibit the growth of most strains of the bacteria.

It also attacked Streptococcus mutans, an acid-producing bacterium which is a major cause of tooth decay.

It is thought that the breaking down of the fatty coconut oil by the enzymes turns it into acids which are active and effective against bacteria.

Previous research found that enzyme-modified milk could stop Streptococcus mutans from binding to tooth enamel.

Researchers now want to look at how coconut oil interacts with Streptococcus bacteria at the molecular level and which other strains of harmful bacteria it can inhibit.

Dr. Damien Brady, who led the research at the Athlone Institute of Technology with Patricia Hughes, a Masters student, said coconut oil could be an attractive alternative to chemical additives.

“It works at relatively low concentrations.

“Also, with increasing antibiotic resistance, it is important that we turn our attention to new ways to combat microbial infection.”

Their studies are also looking into the workings of antibacterial activity in the human gut.

“Our data suggests that products of human digestion show antimicrobial activity. This could have implications for how bacteria colonize the cells lining the digestive tract and for overall gut health,” said Dr. Damien Brady.

A British research team claims that adding enzymes from seaweed microbes to toothpaste and mouthwash could provide better protection against tooth decay.

Researchers at Newcastle University had been studying Bacillus licheniformis to see if it could clean ships’ hulls.

But the scientists now believe it could protect the areas between teeth where plaque can gather despite brushing.

Their lab tests suggest the microbe’s enzyme cuts through plaque, stripping it of bacteria that cause tooth decay.

Dr. Nick Jakubovics, of the university’s school of dental sciences, said: “Plaque on your teeth is made up of bacteria which join together to colonize an area in a bid to push out any potential competitors.

“Traditional toothpastes work by scrubbing off the plaque containing the bacteria – but that’s not always effective – which is why people who religiously clean their teeth can still develop cavities.

“We found this enzyme can remove some of these undesirable bacteria from plaque.”

Plaque is made up of lots of different decaying bacteria.

When bacterial cells die, the DNA inside them leaks out and makes a biofilm that sticks to the teeth.

Instead of removing the plaque entirely, Dr. Nick Jakubovics believes the treatment could strip away the harmful bacteria, like Streptococcus mutans, that cause tooth decay.

“Ultimately we hope to harness this power into a paste, mouthwash or denture-cleaning solution.”

He said more studies are needed to show the technique works and is safe before any products could be brought to market.

He is presenting the latest findings to a meeting of the Society for Applied Microbiology, the organization that is funding the research along with the Newcastle Healthcare Charity.
