Dental floss is one of the essential elements of dental and gum care, and it helps to clean teeth thoroughly and reach places that cannot be easily reached by a toothbrush. It is very important to use dental floss regularly in oral and dental care, because it performs the following task:

1. Removing food debris: Dental floss helps to remove food debris and small particles that cannot be easily reached by a toothbrush, which if not removed can accumulate on the teeth and turn into plaque and cause tooth decay and gum inflammation.

2. Cleaning between the teeth: Dental floss can be used to clean narrow spaces between the teeth that may not be accessible by a toothbrush, in order to avoid the accumulation of tartar and plaque in these areas.

3. Improving gum health: Dental floss helps to improve gum health and keep them clean, as it can remove plaque and tartar accumulated on and under the gingival margin, thus reducing the risk of gum inflammation and bleeding.

4. Improving natural breath: Dental floss helps to remove bad odors that may come from the mouth due to the accumulation of tartar and plaque, thus improving natural breath.

In general, it is recommended to clean your teeth using dental floss at least once a day, and it should be used after brushing your teeth, and it can be used before or after rinsing. You should consult your dentist to determine the correct and appropriate techniques for using dental floss.
