Experts Explain How Water Influences Brushing And Whether It Really Helps, Hinders, Or Doesn’t Change Anything In Cleaning Teeth

It is a habit to m a: apply the toothpaste on the brush and drip a little water before brushing. But does this help or hinder cleaning teeth? Experts consulted by the Tilt portal explained the effects of using water in this process.

Water Reduces Friction in Brushing

According to Ricardo Belchior, professor and coordinator of the Chemical Engineering Department at FEI, using water before brushing can decrease the abrasiveness of the toothpaste. With less friction between the paste and the enamel of the teeth, brushing may be less effective.

Even so, he states that water also plays its role. It helps to dilute the abrasives present in the paste, which improves penetration between the teeth and, consequently, can increase cleaning efficiency.

Water Doesn’t Interfere That Much, Says Expert

For Jaime Aparecido Cury, emeritus professor at Unicamp, water does not compromise the effectiveness of brushing. He explains that toothpaste has rheological properties.

In other words, its components are only activated by friction — such as the friction with the teeth during brushing.

Cury states that even if a person puts a little water, it does not significantly affect the functioning of the toothpaste.

In the lab, to completely dilute a toothpaste, a long process would be necessary, with agitation for several minutes.

Wet Brush Improves Sensation

Dentist Ricardo Jahn, professor at Unisa and specialist in periodontics, also emphasizes that water does not harm oral hygiene.

He recommends only moistening the bristles before applying the paste, to improve the sensation during brushing.

According to Jahn, the ideal is to apply the equivalent of a pea-sized amount of toothpaste on the brush. It is not necessary to cover the bristles with paste.

He highlights that cleaning occurs through the friction of the bristles with the teeth, not by the amount of foam.

Practical Conclusion

Adding a little water to the toothpaste before brushing does not compromise the quality of hygiene. If preferred, just moisten the bristles before applying the paste.

And remember: there’s no need to overdo the amount of paste — a small portion is already sufficient.

The end of Nokia: the brand that was the cellphone of an entire generation has ended its smartphones, left Brazil, and today survives only in basic phones in India while seeking a new partner.

Workers were opening a modern road in Dover when they found, 6 meters below the asphalt, a 3,500-year-old boat made of stitched oak and plant fibers.

Dissatisfied with seeing people sleeping on the street, a man named Ryan Donais started building small mobile homes so that homeless people can escape the cold, each equipped with a bed, running water, electricity, and heating.

Consumers eat six times more chicken than in the 1960s, global meat supply quadruples in 60 years, and FAO report reveals the invisible cost on the plate: livestock could drive 80% of the increase in agricultural emissions over the next decade.

Using high-resolution satellite images, archaeologists rediscovered the Egyptian city of Imet, buried for centuries in the Nile Delta, revealing rare multi-story houses, granaries, and a sacred road linked to the cobra goddess Wadjet, from about 2,400 years ago.

An Indonesian fisherman pulls a mysterious object from the sea and discovers that it is a Chinese underwater monitoring system, part of the so-called Underwater Great Wall that Beijing uses to track submarines and unmanned vehicles in strategic straits of the region.

Two 17-year-old Kenyans use coconut shells, corn cobs, and recycled materials to create an exhaust filter that reduces 93.3% of pollutant particles and wins an environmental award in Africa.

While Brazil uses savings to keep young people in high school, New York wants to deposit up to $3,000 from preschool so that poor children can reach college with less debt and a better chance to change their future.

Brazil may fall behind, and irreversibly so, in the global technological race involving the implementation of Data Centers and investments in Artificial Intelligence (AI). Much smaller but more agile economies, such as those of Argentina and Paraguay, have taken the lead.

China witnesses a slump in car sales as electric and hybrid vehicles surpass 60%, highlighting the silent shift in the world’s largest automotive market.

Brazil is generating so much clean energy that the ONS had to implement an unprecedented emergency plan to contain the solar and wind surplus in the grid.

Electric scooters have helped reduce cars on the streets, but their batteries also age: Lime has made an agreement with Redwood to recycle used packs in the USA, Germany, and the Netherlands and turn tech waste into raw material for new electric vehicles.
