Your dentist will advise you to floss because it removes the food debris from between your teeth in ways that a toothbrush can’t. Food debris can lead to bacteria growth and plaque even if you are stringent in brushing your teeth twice a day.
Your dentist will also advise you on the best ways to floss for the best results:
- Flossing should take you about five minutes to do it thoroughly
- It is best to floss before brushing
- 15-18 inches of floss is the ideal amount
- If your gums bleed regularly when flossing, see your dentist
“If you’re flossing correctly, you shouldn’t be seeing blood, it should take you a few minutes, and you should be using an ample amount of floss.”
