Floss is a very thin string. 


Dental floss is a thin string used to clean teeth. 

A dentist named Levi Spear Parmly invented the first floss. He used waxed silk thread. Later, doctors used silk for stitches. During World War II, a man named Charles C. Bass made nylon floss. Nylon is strong and does not break easily. 

Dental floss is a thin cord used to clean your teeth. 

Cleaning with floss follows a specific way it works. First, you pull a piece of floss from a plastic dispenser. You can use a small blade on the dispenser to cut it. Then, you hold the floss with your fingers or a tool. 
People have been using floss for a long time. A dentist from New Orleans named Levi Spear Parmly invented the first kind. He lived from 1790 to 1859. In 1819, he suggested using waxed silk thread to clean teeth. He believed this was the most important part of oral care. Companies did not sell floss until 1882. In 1898, Johnson & Johnson got a patent for silk floss. This was the same silk doctors used for stitches. During World War II, Charles C. Bass developed nylon floss.
There are many different types of floss to choose from. Some are waxed, while others are unwaxed. 
Choosing the right tool depends on your mouth. Dentists look at the embrasure space to help. This is the triangular space under the contact point of two teeth. 

Dental floss is a thin cord made of filaments used for interdental cleaning. These filaments are typically made of silk or nylon. The primary goal of flossing is to remove food particles and dental plaque. Plaque is a sticky film that adheres to the surfaces of the teeth. While toothbrushes are excellent for cleaning, they often cannot reach the tight spaces between teeth. Flossing allows a person to clean those areas and the spaces below the gumline. 
The process of flossing follows a specific sequence to ensure effectiveness. First, a user pulls a length of floss from a plastic dispenser. They then use a small blade on the dispenser to cut the piece. The user can hold the floss between their fingers or use a specialized tool. 
There are several different types of floss available for various needs. Some versions are waxed, while others are unwaxed. Waxed floss is often coated in materials like polytetrafluoroethylene, also known as PTFE. This coating helps the floss slide more easily and prevents it from fraying. Some waxed varieties even contain antibacterial agents or sodium fluoride. Unwaxed floss consists of multifilaments and may be less expensive. Another type is dental tape, which is wider and flatter than conventional floss. Dental tape is often recommended for individuals with a larger tooth surface area.
History shows how flossing has evolved over many years. Levi Spear Parmly, a dentist from New Orleans, is credited with inventing the first form of dental floss. In 1819, he recommended using waxed silk thread to clean the spaces between teeth. He believed this was the most important part of oral care. However, floss was not sold commercially until 1882. In 1898, the Johnson & Johnson Corporation received a patent for silk floss. This material was the same silk used by doctors for surgical stitches. During World War II, physician Charles C. Bass developed nylon floss. Nylon was better than silk because it resists abrasion and can be produced in many sizes.
Selecting the right tool often depends on the anatomy of a person's mouth. Dental professionals look at the embrasure space to make recommendations. The embrasure space is the triangular area located just below the contact point of two teeth. 
Different tools are used depending on the specific dental situation. For example, a floss threader is a nylon loop that looks like a needle. 

Scientific studies regarding the clinical benefits of flossing show varying results. A 2006 review found that professionals flossing the teeth of schoolchildren resulted in a 40% reduction in tooth decay risk. However, other reviews have suggested that the evidence for flossing as an addition to brushing is limited. A 2011 review noted some evidence that flossing reduces gingivitis compared to brushing alone. Yet, the evidence regarding plaque reduction was described as weak or unreliable. Because of this, many dental professionals recommend flossing on an individual basis rather than as a universal rule. The effectiveness of flossing often depends on an individual's technique and motivation.
