August 3rd (Saturday) methods to reduce bad breath through brushing... Rinsing toothpaste with 'warm water' is more effective!!!

When rinsing your mouth with warm water while brushing your teeth, the effect of removing bad breath is greater than when rinsing with cold water. No matter how hot it is, let's get used to warm water instead of cold water during brushing.

An experiment was conducted on 30 women in their 20s with no periodontal disease, using the same toothbrush and toothpaste, but rinsing with water at different temperatures—cold water and warm water—during brushing. The plaque index and bad breath levels were measured. When brushing with cold water, the plaque index decreased by an average of 22.8 points, while brushing with warm water resulted in an average reduction of 31.3 points. Similarly, bad breath scores decreased by 9.7 points with cold water, but by 13.2 points with warm water.

This is similar to the principle that washing clothes with detergent dissolved in warm water is more effective than in cold water. When brushing your teeth, the cleansing ingredients in the toothpaste dissolve better in warm water, helping to remove plaque more effectively.

"It is best to use water at a temperature similar to body temperature rather than hot water that burns the mouth," he said, "since the ultimate cause of bad breath lies on the tongue, it is more important to clean the tongue thoroughly with a toothbrush to eliminate bad breath."
