A British dentist released a video explaining why it is necessary to brush your teeth before breakfast.

Dentists share videos explaining brushing their teeth before breakfast.

Anna Peterson, a dentist in London, England, has become very popular on Dido.

The video that went viral on the Internet shows that she answered an old question: Should people brush their teeth before or after breakfast?

A few days ago, she uploaded a video suggesting that the audience brush their teeth before breakfast to ensure the best hygiene.

Experts in Peterson say that brushing your teeth after breakfast will have a long-term negative effect on your teeth.

She explained: "When people eat breakfast, their mouth is acidic, so brushing their teeth after breakfast means brushing acidic things on their teeth, which will damage the enamel."

Expert Peterson said that brushing teeth before breakfast is actually protecting enamel from acid damage.

A netizen commented: "After watching your video, 10 minutes learned more than in the past 32 years."

Another person wrote: "I forwarded this video to my friends because I once told them that I brushed my teeth before breakfast and they laughed at me." Even my teacher said to brush your teeth after breakfast. "

Others think Peterson's advice is common sense. Strangely, some people don't even know when to brush their teeth and when not to.

A Didi user wrote: "I think everyone does this?" Isn't it obvious? "

Another person asked, "I think people brush their teeth before breakfast." How can they have breakfast without brushing their teeth? "

Although Peterson's video was a suggestion, it was criticized by some followers who complained that brushing your teeth before breakfast would change the taste of food.

One person said, "I don't want breakfast to smell like mint."

Another person wrote, "I'd rather toast tastes like toast than mints."

Peterson said that if someone insists on not brushing their teeth before breakfast, there is a simple compromise.

She said, "Wait 30 minutes before brushing your teeth."

Peterson explained in another video that saliva will "naturally" restore the pH value of the human body after eating, but the longest time will be 1 hour.

She suggested: "Use fluoride toothpaste because it can strengthen enamel."

Regarding oral hygiene, Peterson released a video containing information, not 1 time. She also released a video that revealed some mistakes people often make when brushing their teeth, such as using oral cleaner directly after brushing their teeth.

She said, "This will corrode teeth." It is also said that oral cleanser will wash away all the high-concentration fluoride contained in toothpaste.

It is actually good for both husband and wife to sleep separately in family life.
