By now you’ve probably seen the headline on this story: “The best white teeth whiteners.”
It’s not that they’re the best whiteners.
It’s that they’ve been proven to be the best way to whiten your teeth.
It could be that they don’t work for you, but it’s the best you can do.
The answer to that question comes from a team of researchers led by University of Melbourne’s Dr Peter Sacks who, in a new study, conducted a meta-analysis to find out which whitening products were the best for teeth whiteness.
Their research, published in the journal PLOS ONE, looked at studies on different whitening technologies and found that the most commonly used tooth whitening agents were whitening creams, toothpastes, fluoride toothpaste, and mineral toothpaste.
As well as the above, Dr Sacks also found that whitening gel, mouthwash and lotion were also used in the US, while the UK and Canada are using whitening mouthwashes and lotions.
Dr Sacks said that tooth whiteners were a key part of the strategy for people to achieve better whiteness and, in the future, would also be a key factor in treating people with conditions like rosacea and keratosis placida.
“The whitening industry is very competitive, there are only a handful of brands that have an edge over the other,” he said.
“That means that you’re not going to be able to use a product that’s been around for 30 years, or that is only available in certain regions, or a product made for the last 10 years.”
Dr Saks said that the key to success with whitening was to get people to use the right products.
People who choose to go for the “white” option need to know the product is safe and effective, he said, adding that people could go a long way to improving their whiteness by using a different whitener than the ones that are recommended.
Whitening creamer has been around since the 1950s, Dr Tanya Loughran from the University of Sydney’s Department of Oral Biology and Clinical Research said.
In fact, the US Food and Drug Administration (FDA) gave whitening cream a “fresh” status in the 1980s and a “new” status by 2005, she said.
Dr Loughren said that whiteners have been around longer than people realise, with the development of products like whitening gels and whitening pads, which were made for people with skin conditions.
She said the fact that there was no consensus on which whiteners worked best was an “interesting phenomenon” and that it’s important to take a look at the research before you make any sweeping statements about what works best for you.
“I think the research is very complex, it’s not just one product, there’s a lot of different products out there that people use and what works well for them,” she said, noting that there are different types of whitening for different skin conditions and there are some brands that don’t have the best results for people.
Another factor to consider when buying toothpaste or other products is what they’re formulated for.
Dr Sashes findings showed that toothpastors are the best option for people who are already using toothpaste and gum, while mineral toothpasthes and mouthwash can be good choices for people wanting a better whitening experience.
Dr Sashes study found that people who used the highest amount of toothpaste products had the highest levels of whiteness in their teeth, which he said was “a bit surprising” given that toothpaste contains less calcium than gum.
A study of more than 12,000 Australians found that using toothpastives led to a 30 per cent increase in the amount of calcium in the teeth.
Dr Tanya said that people often think whitening whitening isn’t worth the extra effort because it doesn’t require much, and people can go on using tooth whitener all day without worrying about any side effects.
But it’s a false assumption, she added.
“People don’t know what they are doing.
If you’re going to use toothpaste every day, you’ve got to know how much you’re using, how often you’re taking it, and how much is the benefit you want.”
