Is it okay to brush your teeth for too long?

Many people try to prolong the time when brushing their teeth, thinking that this will make the oral cavity more hygienic and reduce periodontal diseases. In fact, when brushing your teeth, it is best to keep it for a moderate time. Brushing for too long may cause certain damage to your teeth and even make you more prone to oral diseases. Next, I will introduce some precautions about brushing your teeth.

The researchers recorded the level of plaque before and after brushing and found that as the brushing time and force increased, the plaque gradually decreased. However, the results also showed that when people brushed for more than 2 minutes and used more than 150 grams of force, they did not remove more plaque.

People should brush their teeth for 2 minutes, using about 150 grams of force, which is the weight of an orange.

The researchers tested 16 different toothbrushing techniques, varying the duration and intensity of the brushing. The brushing time tested ranged from 0 seconds to 3 minutes, while the force used ranged from 75 grams to 300 grams. The investigators recorded the degree of dental plaque before and after brushing and found that as the brushing time and force gradually increased, the dental plaque gradually decreased. But the findings also showed that when people brushed for more than two minutes and used more than 150 grams of brush, they did not remove more plaque.

The study's leader, Dr. Sisman, said the findings showed people shouldn't brush their teeth for too long or too hard. "It's almost impossible for the average user to be sure they are brushing with the right pressure," he said. "For example, you may use a light force with your toothbrush, but because you are brushing a small area, the pressure could be much greater.

Therefore, when brushing your teeth, it is best to keep it for about two minutes, and pay attention to maintaining a certain force. To maintain oral hygiene, in addition to brushing your teeth in the morning and evening, you should also rinse your mouth in time after eating, especially before going to bed at night, try not to let food residues stay in the mouth for too long.
