Enamel Dentistry’s 2026 Guide to Flossing for Healthier Gums

Flossing is the mechanical removal of plaque, bacteria, and food debris from between the teeth and below the gum line. Recent medical literature supports that flossing shows less periodontal disease, fewer dental caries, and loss of fewer teeth over 5 years [1] (Marchesan et al., 2020). Flossing is essential for preventing gingivitis and periodontal disease. Research has indicated that flossing cleans the rest of the tooth that is missed during brushing. Flossing disrupts the bacterial colonies that cause inflammation, cavities, and bad breath. Instead of snapping the floss strings down between teeth, our team recommends wrapping the floss around the tooth to remove the plaque efficiently. While string floss is the default option, water flossers and interdental brushes are great alternatives for patients with braces and bridges. This guide from Enamel Dentistry near Pilot Knob explains the best flossing technique and flossers to use.

Simply brushing does not clean enough under the gumline to prevent gingivitis and periodontal disease. Medical literature supports that flossing is associated with a modestly lower prevalence of periodontitis [2] (Cepeda et al., 2017). When flossing is skipped, bacteria accumulate underneath the gumline. Within 24-48 hours, the plaque can harden into tartar, which needs to be removed with professional scaling and root planing. This buildup of tartar triggers the immune system, which can lead to inflammation, red gums, and periodontal disease.

Effective flossing is not only about removing debris; it is also about scrubbing the sides of the teeth. To get the best result without damaging your gum tissue, follow this method recommended by our Enamel Dentists near Pilot Knob: 

  1. Break off about 18 inches of floss and wind the floss around your fingers. Leave about an inch or two of string to use on the teeth.
  2. Hold the floss taut between your thumb and index fingers. 
  3. Gently guide the floss between your teeth using a sawing motion and never snap it into the gums. 
  4. When the floss reaches the gumline, it forms a C-shape against one tooth. Move the floss gently into the space between the gum and tooth. 
  5. Scrape the side of the tooth, moving the floss up and down away from the gum with up and down motions. 
  6. Repeat this for the adjacent tooth. Be sure to unroll the floss from your fingers as you go to the next gap in teeth.

The C-shape technique, where the string is wrapped around the tooth to remove plaque,  is a great method of flossing. Unlike the snapping of floss between the teeth, which only removes food caught between the contact points, this method is designed to scrub the surface of the tooth and clean below the gumline. If you floss without the C-shape technique, you only clean the tiny point where the teeth touch, missing the majority of the surface area. Deep cleaning allows the floss to slide 2-3 millimeters down into the sulcus, disrupting the bacteria that cause periodontal disease. By using the C-shaped technique, you avoid snapping the floss into the delicate gum triangle, which ultimately prevents cuts and gum recession. 

You are flossing too hard if you see physical cuts or experience sharp pain rather than pressure. While minor bleeding is often a sign of gum disease rather than aggressive flossing, actual trauma to the tissue feels different. If you hear a loud pop or snap when flossing through the contact point, too much force is being applied. This motion sends the string slicing into the gums. If your gums appear to be bleeding and pulling away from your teeth, you may be scrubbing too aggressively. If a thin white line or a V-shaped cut is observed on your gums immediately after flossing, the tooth has been traumatized.

For patients who have braces, a water flosser is an effective and time-saving alternative. Water flossers are as efficient in removing interdental plaque in a single use [3] (Abdellatif et al., 2021). Threading string floss between wires is difficult, which leads many orthodontic patients to skip flossing entirely. We recommend 4 products for patients who have braces, including water flossers, interdental brushes, super sloss, and floss threaders. For Pilot Knob residents who dislike traditional string floss or simply want a more efficient option, we highly recommend water flossers. They are the “Tesla” of dental hygiene: fast, efficient, and enjoyable to use. They are especially beneficial for orthodontic patients who would spend significant time maneuvering floss around brackets and wires.

1. How do I know if I am flossing too hard?

If you are snapping the floss down and cutting your gums, you are flossing too hard. You should feel pressure, not pain, on the gum tissue.

2. Why do my gums bleed when I floss?

Bleeding is usually a sign of inflammation. It is a common misconception to stop flossing when you see blood. But you need to floss more consistently.

3. What are the alternatives to flossing if I have braces? 

Braces can be very tedious. We highly recommend water flossers.
