A typical morning routine for most will include brushing our teeth using toothpaste and following up with a mouthwash of some sort.
But one dentist has revealed the unexpected reason why you should never do this in a TikTok video that’s surprised followers. .
Dentist Anna Peterson, who is based in London, revealed many of us may have been cleaning our teeth wrong for years, saying that you should use mouthwash after you eat or before brushing your teeth, and not after.
It’s all down to flouride concentrations, which are lower in mouthwash than toothpaste, meaning you wash away the more concentrated flouride if you use it straight after brushing.

The expert explained that toothpaste has roughly 1450 parts per million fluoride, meaning it has a high concentrate to protect your teeth.
She says: ‘Your toothpaste that you brush your teeth with has around 1450ppm fluoride.
‘Your mouthwash has only 220ppm fluoride. This is a much lower concentration and it’s not enough to protect your teeth from sugars that you eat and drink.
‘So when you brush your teeth, and you rinse with mouthwash straight away – you just rinse off all the high concentration fluoride, for a low concentration fluoride.’

She added: ‘And in our evidence based toolkit for delivering better oral health, all dentists should be following this.
‘And by no means am I against mouthwash. Because I do actually recommend it to my patients. But not every patient needs it. I certainly don’t tell them to use it after brushing.’
Viewers couldn’t believe the news, and flooded the comments, with one writing: ‘What? Everyone rinses with water after brushing. Who is leaving toothpaste on their teeth?’
Anna replied: ‘Rinsing with water is better than rinsing with mouthwash, just brush then spit out the excess, try not to rinse.’
She said that you should use mouthwash after you eat or before brushing your teeth, and not after, as the mouthwash has a lower concentrate of fluoride
Another viewer wrote: ‘OK, nice to know i’ve been doing it wrong my whole life.’
A third wrote: ‘I floss, then mouthwash, then brush. Does that work?’
Anna replied: ‘Yes, that is fine to do, mouthwash is best to be used after you eat, but no harm doing it this way.’
The dentist went on to give her followers a follow up video with more detail about when they should be using mouthwash.
One user asked: ‘Can you please do a video to explain when and how often to use mouthwash?’
Anna replied: ‘Okay so loads of you are asking this question and I’m sure a lot of you are wondering, “well why do we even have mouthwash?”.

Viewers couldn’t believe the news, and flooded the comments, with some questioning who rinses with mouthwash and others asking for advice on their own routines
‘Mouthwash is a fantastic product to use, but you have to use it at the right time of day.’
She went on to explain when is best to use it, and informed viewers of the science behind what eating does to your teeth.
She added: ‘So you wake up in the morning, you’ll floss your teeth, brush your teeth and then you’ll go and have breakfast.
‘And pretty much anything you’re going to eat will contain sugars of some sort. And what happens when you eat sugars, your mouth becomes acidic.
‘So it drops in pH. And it drops below 5.5, which is the critical pH, and we call this an acid attack.
‘During an acid attack, your teeth start to dissolve. Now if you were to go and brush your teeth at this point, what’s happening is that you’re brushing the acid into your tooth.
‘And this causes tooth erosion. So to get your teeth out of this critical zone, use mouthwash.’
