1. What is dental floss and why is it essential?
Dental floss is an oral hygiene tool designed to remove plaque and food debris where a toothbrush can't reach: between teeth and under the gum line. It's one of the most effective habits for preventing cavities , gingivitis, and bad breath, yet it's often overlooked: according to estimates, less than 30% of Italians use it every day.
Using it regularly means stopping the formation of tartar , which once solidified can only be removed by the dentist, and maintaining healthy gums.
2. Floss before or after brushing?
The debate remains open, but most dental practices agree: flossing before brushing allows the active ingredients in toothpaste, such as fluoride, to better reach the interdental spaces already cleared of residue.
What really matters, however, is consistency : doing it every day, preferably in the evening, makes the difference.
3. How to use dental floss step by step
-
Cut a length of about 40 cm and wrap it around the middle fingers of both hands, leaving 2–3 cm of taut yarn.
-
Gently insert it into the space between two teeth, guiding it with your thumbs and forefingers.
-
Hug the tooth in a “C” shape and slide the floss from top to bottom, even under the gum line.
-
Always use a clean end of the floss for each tooth and rinse with mouthwash after brushing.
If bleeding begins, do not stop: it is often a sign of inflamed gums that will improve with continued use.
4. Waxed or unwaxed dental floss?
The main difference is in the wax coating :
-
Waxed → more resistant and smooth, ideal for those with crowded or irregular teeth.
-
Unwaxed → thinner and more abrasive, perfect for very tight spaces.
Some versions include menthol flavors or fluoride, but the choice depends on the shape of your mouth and gum sensitivity . The best advice is always from your dental hygienist.
5. Best Dental Floss: How to Choose It
There is no universal “best dental floss,” but the best one for you :
-
For narrow teeth : thin wire or monofilament in PTFE or ultra-flat nylon.
-
For braces or bridges : spongy floss or “super floss” with a stiff end to fit under the orthodontic arch.
-
For implants : floss with a spongy part and soft bristles to avoid irritating the gum line.
-
For sensitive gums : waxed or natural silk floss, which is more delicate.
Today there are also biodegradable and PFAS-free options, which are safe and sustainable.
6. When to floss
Experts recommend brushing at least once a day , preferably in the evening before brushing your teeth. It only takes two minutes to achieve effective results.
However, avoid using it immediately after an extraction or in the presence of acute inflammation without consulting your dentist.
7. Benefits of Flossing: Much More Than Aesthetics
How to floss correctly:
