Why Flossing Is So Important

People who floss regularly have healthier gums. They have less gum bleeding, gum disease, bone loss, and inflammation. Adding dental floss into your daily oral hygiene routine will help remove plaque and eliminate bacteria that can lead to gingivitis, tooth decay, and bad breath.

The main thing to remember is that you should brush your teeth, floss, and use mouthwash every day! Any type of floss will improve your oral health and pick up bacteria that your toothpaste and toothbrush left behind. That being said, certain flosses will fit your personal preference and needs better than others.

6 Best Manual Types of Floss

Listerine Ultraclean Dental Floss

Listerine Ultraclean Dental Floss

Johnson & Johnson Listerine Ultraclean (Formerly Reach) is a great all-around floss and is often recommended by dentists and hygienists. It does a great job of removing plaque buildup that brushing misses, and it is nice and thick, so it won't shred while you're flossing. Plus, it has a fresh cool mint flavor.

Glide Pro-Health Clinical Protection Floss

Oral-B Glide Pro-Health Clinical Protection Floss

For people with tight spaces in their teeth, some flosses may be too thick. Oral-B's Glide floss is waxed to help it “glide” through your teeth without snapping into your gum line. It’s thin enough to fit between tight spaces to remove plaque and food particles, but strong enough that it doesn’t shred.

4 Best Water Flossers of 2021

Water flossers, also known as irrigators or piks, provide an alternative to floss for people unable to add flossing into their daily routine. They require less dexterity than regular flossing while delivering many of the same benefits, including the removal of plaque and calculus. 

Ideally, water flossers are used in addition to traditional floss. The combination will provide the best cleaning of your teeth and gum tissue.

Dental Floss FAQ

What is the best dental floss to use?

Johnson & Johnson Listerine Ultraclean (Formerly Reach) is one of the top flosses. It often gets recommended by dentists and dental hygienists.

What is the best tool for flossing?

Traditional floss is the best tool in most cases. Floss picks can also help you clean hard-to-reach places. If you have braces, a floss threader makes it easy to clean your brackets and the area around them.

How do you floss with tight teeth?

Use a thin floss designed for tight spaces like Oral-B Glide Pro-Health Clinical Protection Floss.

Which is better floss or floss picks?

Traditional floss can bend and wrap around your teeth better than the straight piece of floss that floss picks use. However, some people find that floss picks help them clean hard-to-reach places.

Is dental floss or tape better?

Dental tape is wider and flatter than regular dental floss. People with tight spaces between their teeth usually prefer dental floss, while people with wider spaces may enjoy dental tape. Both are available in waxed or unwaxed versions.

Is Reach dental floss discontinued?
