Toothbrushes -even electric ones- can only clean the teeth by 60%, they cannot remove all the plaque on the teeth because it is challenging to reach between the teeth. We have to use dental floss to clean the areas between the teeth.

It has also been proven by scientific studies that dental floss prevents cavities between the teeth and reduces gingivitis. 

Dental floss is the most important step in oral care after toothbrushes and toothpaste. Flossing at least once a day will have a very positive effect on oral health.
