I'm a dentist - this is the trick I use every night so I can eat as many sugary sweets as I like without tooth decay
A dentist has shared her number one hack for how to reverse tooth decay in its early stages - and it means you can 'eat all the sweets you want'.
Dr Shaadi Manouchehri, from London, said the simple routine can be done once a day after brushing your teeth.
'Get a little bit of fluoride toothpaste and get your interdental cleaning brush and coat it with the toothpaste,' she advised.
The doctor then took the coated brush, pushing it into the spaces between the teeth.
Dr Manouchehri explained that this would deliver 'much-needed' fluoride between the teeth, which is the 'number one spot where cavities begin'.
The dentist of ten years said it was important not to eat for 30 - 60 minutes after applying the toothpaste, so that it can better work its magic.
The hack promises cleaner and healthier teeth and can even undo some existing damage.
'It can actually reverse decay in it's early stages,' she said.
Dr Michael Cai, a Sydney dentist, spoke to FEMAIL about the controversial attitude around fluoride based toothpaste, insisting it is safe to use and the best option for anyone with signs of tooth decay
Many agreed they 'need to try this' - and dentists backed her advice as well.
'Wow, I've been telling my patients this for years! I do it all the time - love my interproximal brushes,' one dentist said.
'I have been doing this for years, works 100 per cent!' another chimed in.
Others said they follow a similar dental routine, but simply use floss coated with fluoride toothpaste instead of an interdental cleaning brush.
Some, however, were outraged at the recommendation to use fluoride toothpaste.
The controversial ingredient is still seen as 'unsafe' by some despite dentists and health experts in Australia encouraging its use in small amounts.
'As soon as you said fluoride, I'm out!' one woman said.
'It's shocking the way she's advertising it!' another woman agreed.
Sydney dentist Dr Michael Cai from Pitt Street Dental spoke to FEMAIL and said it's perfectly safe to use.
'Studies have shown that fluoride reduces the risk of cavities, when it was introduced into water supplies there was a reduction in dental decay all over the world,' Dr Cai said.
He explained that fluoride is like anything else in life, excessive amounts can cause harm to health, but it is not toxic in small amounts.
'Natural toothpaste is not as effective as fluoride toothpaste,' he said.
'In patients where there is a history of dental decay we see a dramatic increase in cavities when using natural toothpaste as compared to people using fluoride toothpaste.'
Dr Cai did say it's fine for people with healthy teeth and no cavities to opt for fluoride free toothpaste, but those with tooth decay should steer clear of natural brands.
