You need a scientific study to know that rotting food smells bad? Sure: > Our study confirmed that use of dental floss was associated with lower odds of having oral malodor after controlling for other factors. This agrees with the findings reported recently by AlSadhan [15] who demonstrated statistically significant relationship between self-reported halitosis and use of dental floss. Faveri et al.[32] evaluated the effect of interdental flossing on oral malodor and found that there was a significantly lower concentration of sulfur compounds after using dental floss. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5727733/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5727733/
