Is two minutes of brushing enough? Here is what the evidence proves

Many people know that to keep your teeth and mouth healthy, you need to brush your teeth at least twice a day for at least two minutes at a time.

Some people overestimate how long it takes to brush your teeth, however, there is some evidence that even a two minute brushing may not be enough.

According to research, the best results for removing dental plaque as much as possible (also known as microbial plaque, oral biofilm, dental biofilm, also known as dental plaque biofilm or bacterial plaque biofilm) can be achieved in three to four minutes.

Does this mean we have to double the brushing time?

Dentists began to recommend brushing teeth for two minutes in the 1970s, followed by the use of a soft bristle brush. However, today’s consensus is largely based on studies published since the 1990s that looked at the timing and techniques of brushing and the type of toothbrushing.

These studies show that two-minute brushing leads to better (but not better) plaque reduction. But while brushing for more than two minutes removes excess plaque, there is still a lack of research to examine whether brushing for more than two minutes is associated with long-term oral health.

Based on what we know about the damage caused by microbial plaque, removing it every time we brush is associated with better oral health.

The lack of this evidence is significant due to the difficulty in conducting long-term studies.

When we brush our teeth, we do it with the main goal of removing the germs called tooth plaque from the surface of the teeth. This plaque is an accumulation of bacteria, fungi and viruses that live together in a community called microbial biofilm. Biomass is very viscous and can only be removed with a brush.

Many things facilitate the growth of these germs, such as the rough areas on the tooth surface (such as some fillings), the inability to reach certain areas with the toothbrush (such as the gaps between the teeth) or the use of braces.

In fact, plaque biofilms develop on our teeth within a few hours of brushing, which is why we recommend brushing twice a day.

Failure to brush our teeth properly or for a long period of time can lead to large amounts of plaque, which can eventually activate the body’s immune system and eventually lead to conditions such as gingivitis.

The infection is usually painless, but there is bleeding gums and sometimes bad breath when brushing teeth. Biofilms can also cause tooth decay.

The right technique

The goal of brushing teeth is to minimize microbial plaque on each tooth as much as possible.

Current evidence suggests that spending more than four minutes brushing each time will clean your teeth.

If this is the long brushing time, we can reach the most effective and difficult places for brushing teeth.

But be careful not to brush too much (more than twice a day) and avoid brushing vigorously or using abrasive toothpastes and brushes as this can damage our teeth and gums, especially when using toothpaste or abrasive toothpaste with hard bristles.

There are various brushing techniques you can use to brush your teeth properly. One of the most recommended techniques is to brush below and below the gum line, as plaque will first form and cause swelling.

Also to avoid damaging the soft and hard tissues in the mouth, always brush your teeth using a soft brush.

Many factors can affect the technique you use, the type of brush, toothpaste or floss. For example, those who have damaged the surface of their teeth due to drinking highly acidic beverages may have weaker teeth.

This may mean that they are more likely to have further tooth damage if they use abrasive toothpaste and hard bristles on their toothbrush. Therefore, it is recommended to consult a dentist to find out what you should use to clean your teeth.

Studies have shown that flossing can reduce tooth decay and gingivitis, so interdental cleaning is recommended in addition to brushing teeth, which most of us know as flossing.

The best method of flossing is to move the floss between the gums and teeth, holding it firmly on the tooth, gently rubbing the surface of the tooth up and down, and slowly advancing. Under the gum line.

Although we are accustomed to the advice to brush our teeth twice a day for two minutes at a time, it is important to focus on using the right technique to ensure that we brush our teeth well and correctly.
