Did You Know There is More Than One Type of Floss?

A variety of dental flosses are commonly available. Floss is available in many forms including waxed, unwaxed monofilaments and multifilaments. Dental floss that is made of monofilaments coated in wax slides easily between teeth, does not fray and is generally higher in cost than its uncoated counterparts. The most important difference between available dental flosses is thickness. Waxed and unwaxed floss are available in varying widths. Studies have shown that there is no difference in the effectiveness of waxed and unwaxed dental floss, but some waxed types of dental floss are said to contain antibacterial agents and/or sodium fluoride. Factors to consider in choosing a floss include the amount of space between teeth and user preference. Dental tape is a type of floss that is wider and flatter than conventional floss. Dental tape is recommended for people with larger tooth surface area.

The ability of different types of dental floss to remove dental plaque does not vary significantly; the least expensive floss has essentially the same impact on oral hygiene as the most expensive.

Factors to be considered when choosing the right floss or whether the use of floss as an interdental cleaning device is appropriate may be based on:

• The tightness of the contact area: determines the width of floss
• The contour of the gingival tissue
• The roughness of the interproximal surface
• The user's manual dexterity and preference: to determine if a supplemental device is required

Specialized plastic wands, or floss picks, have been produced to hold the floss. These may be attached to or separate from a floss dispenser. While wands do not pinch fingers like regular floss can, using a wand may be awkward and can also make it difficult to floss at all the angles possible with regular floss. These types of flossers also run the risk of missing the area under the gum line that needs to be flossed. On the other hand, the enhanced reach of a wand can make flossing the back teeth easier.

Dental floss is the most frequently recommended cleaning aid for teeth sides with a normal gingiva contour in which the spaces between teeth are tight and small. The dental term ‘embrasure space’ describes the size of the triangular-shaped space immediately under the contact point of two teeth. The size of the embrasure space is useful in selecting the most appropriate interdental cleaning aid.
