What Horrors Are Hidden in Your Toothpaste?
Could your toothpaste be harming your health? That’s the very real concern of a growing group of dentists who believe that far from being an essential part of our daily regimes, many commercial toothpastes contain substances detrimental to our health.
These chemicals have been linked to possible oral and breast cancers, neural and cardiac ailments, as well as mouth irritations, gum damage and environmental pollution.
Dr Toby Talbot is an expert in restorative dentistry and a member of the Royal College Of Surgeons. After more than 35 years in the profession, he believes the products we find on supermarket shelves are often grounded in industrial chemistry rather than medicine.
‘The public are smart, but they need to see past the marketing and be well-informed about what they are buying,’ he says. ‘Some products use a slogan indicating that they are “the leading products used by dentists”, but that’s because they send free products to every dentist in the country.’
Here are the ingredients that most concern Dr Talbot…
DETERGENT THAT CAUSES MOUTH ULCERS
Sodium Lauryl Sulphate (SLS), causes Dr Talbot much concern. ‘It’s in 85 per cent of toothpastes and is used as a wetting agent (something that allows the paste to spread more easily) that helps the peppermint oil used for flavouring mix with the water contained in the product. Without SLS, these elements would separate in the tube.
‘The problem with SLS is that it opens up the gaps between the mucosal — skin — cells in the mouth, which allows toxins or carcinogens to get in [these can come from all manner of sources including tobacco smoke].
‘Oral mucosa is one of the most delicate tissues in our body and SLS is effectively a detergent,’ says Dr Talbot. This harsh detergent can cause irritation and abrasions or breaches in the skin inside of the mouth, which cause chronic mouth ulcers. ‘If I see a patient suffering with recurrent mouth ulcers, one of the first things I do is prescribe the use of a non-SLS toothpaste,’ he says.
THE CHEMICAL REMOVED IN THE US, BUT NOT HERE
Last year, the company behind Colgate toothpaste removed products containing triclosan — a chemical used to prevent gum disease — from the shelves in the U.S. after the public became aware that a chemical within it was linked to cell cancer growth.
While Colgate insists triclosan is safe in small doses, subsequent findings have also shown toothpaste is an effective vehicle for triclosan to get into the body.
‘Triclosan is used in toothpastes by industrial chemists to stop the formation of bacteria,’ says Dr Talbot. ‘There was an outcry about products containing this ingredient in the U.S last year. It is still present in UK versions, though.
‘Some animal model studies have shown triclosan has an effect on hormone activity and potential for carcinogenic activity.’
Responding to the controversy, Patricia Verduin, head of Colgate-Palmolive research and development, said: ‘Recent claims that triclosan in Colgate Total can lead to cancer are absolutely untrue. Global regulators have reviewed the issue of carcinogenicity and have concluded that triclosan in consumer products does not pose a human cancer risk.’
