The Best Dental Floss: Our Picks

Guide: Questions you should ask yourself before buying dental floss

What material is dental floss made of?

Dental floss can be made of two materials, either plastic or real silk. They are also available in waxed or unwaxed form. Dental floss made of plastic is usually made of nylon or polyethylene, which can also have a PTFE coating (Gore-Tex or Teflon).

In addition, some dental flosses are also coated with fluorides or aromas. If sustainability is important to you, a floss made of real silk that is compostable is the right choice.

This is made of natural floss and is always coated with beeswax. In order to give you the advantages of each of the two most commonly used types of material, we have created the following overview.

Advantages Disadvantages
Dental floss made of plastic fibres lightly (cleans even better), elastic, is available waxed - good for sensitive gums made from petroleum
Dental floss made of natural floss compostable, open-pored - cleans better, soft, plastic-free not vegan

Can I reuse dental floss?

Dental floss should not be reused more than once, as it has already absorbed quite a bit of plaque and bacteria after one use.

Why should you floss?

You should floss once a day because it allows you to reach places that an (electric) toothbrush cannot. The aim is to clean the interdental spaces, which make up 30 per cent of the tooth surface.
Did you know that about 20 million bacteria live in our mouths?

About 20 million bacteria live in our mouths. Some of them block pathogens, while others are responsible for causing tooth decay. They are also responsible for bad breath.

Plaque, i.e. bacterial plaque, is deposited especially in the spaces between the teeth. If this builds up and increases, it can lead to caries and periodontitis.

To avoid expensive visits to the dentist and painful treatments, interdental care is extremely important. In addition, you can also use mouthwashes or tongue cleaners, for example.

It is ideal to floss once a day. It is better to floss first and then brush your teeth.

How to floss properly?

Not only is daily use important, but also correct handling. You should pay attention to a tight thread and the correct posture. You can floss either in the morning or in the evening before brushing your teeth. It is best to take a 30 to 40 centimetre long string, wrap it once around both index fingers and tighten it.

Then gently push the thread back and forth between your teeth. Then place the thread in a c-shape around the tooth and move it up and down. Also make sure to clean the gum line. If flossing causes you to bleed, you either need to be more careful or change flossers.

However, you may have gingivitis, in which case you should consult a dentist. You should also make sure that you use the right floss for you. For example, there are fluffy flosses with a round cord shape that should be used when caring for larger spaces between teeth, such as bone loss or dentures.

For precisely divided use, on the other hand, a flat and smooth dental floss, also called a dental band, is recommended. This gets into the narrow spaces between the teeth without any problems and can thus prevent caries.

Did you know that every German uses about 1.5 metres of dental floss per year? On average, every German uses 1.5 metres of dental floss every year. That sounds like a lot at first, but it's not. In fact, it is 178.5 metres too little. Although tooth decay mainly forms in the interdental spaces, it is simply easier to just brush your teeth with a toothbrush and forget to floss.

How much does dental floss cost?

There are different prices depending on the material and manufacturer. However, most are in a price range below ten euros.
Floss type Quantity Price range
Nylon unwaxed 50 metres 1,50-4 €
Nylon waxed 50 metres 1,70-7 €
Superfloss 50 pieces 2-8 €
Natural floss 10 metres 1,70-5 €
Floss sticks 30 pieces 2-7 €

Decision: What types of dental floss are there and which one is right for you?

Basically, you can distinguish between four different types of floss products:

  • Unwaxed floss
  • Waxed floss
  • Floss dental floss
  • Flossette

We would therefore like to introduce you to the different types in the following section and help you find out which floss is right for you. For this purpose, we will introduce you to the above-mentioned types in more detail and clearly illustrate exactly what their advantages and disadvantages are.

What are the characteristics of unwaxed floss and what are its advantages and disadvantages?

Unwaxed floss is the most natural way to clean your interdental spaces. In principle, you should floss your teeth at least every two days to remove stubborn plaque and prevent tooth decay. However, if you have never flossed before, you should buy waxed floss.

This will allow you to slowly get your gums used to cleaning, as they may bleed slightly after the first few uses.

Advantages
  • High cleaning effect
  • Very inexpensive
Disadvantages
  • Floss frays easily
  • Not suitable for sensitive gums

Cleaning your interdental spaces is easier due to the fact that unwaxed floss frays slightly when used. However, the floss can also get caught on fillings and get stuck or tear apart.

What are the characteristics of waxed floss and what are its advantages and disadvantages?

Waxed dental floss is particularly suitable for people who have very sensitive gums or find it difficult to reach narrow spaces between teeth. Bleeding gums are no longer an issue due to the smooth surface of the floss. The surface structure of a waxed floss minimises friction to guarantee a trouble-free brushing experience.

However, small amounts of wax can get stuck in the interdental spaces during cleaning.

Advantages
  • Suitable for sensitive gums
  • Fresh taste after cleaning
Disadvantages
  • Wax can get stuck in the interdental spaces
  • Coated floss is not environmentally friendly

The floss can be coated with wax or a PTFE compound. PTFE is a polymer also known as Teflon and Gore-Tex. Dental floss coated with PTFE is practical in dental care but unfortunately not environmentally friendly.

Most products are additionally coated with fluorides and flavourings. This not only prevents the formation of caries during use, but also spreads a pleasant taste in the mouth. Typical flavourings include mint or eucalyptus.

What are the characteristics of floss and what are its advantages and disadvantages?

A fluffy dental floss is especially perfect for cleaning braces and hard-to-reach areas that are just above the gums. A fluffy floss consists of a regular part and a thicker fluffy part.

The fluffy section is stretchy and provides a large surface area for thorough cleaning of your interdental spaces. Most of these flosses are equipped with a reinforced end to easily reach into narrow spaces.

Advantages
  • Perfect for cleaning braces
  • Thorough cleaning due to the large surface
Disadvantages
  • Higher consumption due to pre-cut pieces
  • Relatively expensive

An interdental brush can be used as an alternative or supplement to floss. With such a brush, small wires with bristles are clamped in place, which can be used to specifically remove deposits in the interdental spaces.

What are the characteristics of a flossette and what are its advantages and disadvantages?

The flossette is also often called a floss stick or dental violin and is a plastic holder that holds a piece of floss for cleaning your interdental spaces. The plastic construction keeps your hands and bathroom mirror clean. The flossette is also much easier to use than conventional dental floss.

This makes dental care easier, especially for children who are still very inexperienced.

Advantages
  • Easy to use
  • hands stay clean
Disadvantages
  • Cleaning effect not optimal
  • disposable products generate a lot of waste

Since the floss is already pre-tensioned in most holders, the flossette has to be rinsed off after brushing each intermediate area. This means that the cleaning effect is not optimal, as residues can be pushed back into other interdental spaces.

Buying criteria: You can compare and evaluate dental floss based on these factors

In the following, we would like to show you important factors that you can use to compare and evaluate dental floss. This should make your purchase decision easier. In summary, the following criteria are taken into account:

  • Material
  • Coating
  • Scope of delivery

In the next paragraphs we will explain the purchase criteria in more detail and how they are to be evaluated.

Material

This decision is primarily about whether you prefer a natural product or the cheaper version. Natural floss is obtained from silkworms and in most cases coated with beeswax. Therefore, this floss is not vegan. Nylon or polyethylene floss are plastics made from petroleum, among other things.

Since the production is much cheaper, this type of floss is very inexpensive. Floss, also known as Superfloss, Special Floss or Ultrafloss, is also made of plastic and is very popular because of its material properties.

It is more expensive than regular floss, but if you are a newcomer to flossing, this product may be worth your while.

Coating

Basically, there is no difference in the cleaning effect of unwaxed or waxed floss. Here, the purchase decision depends a lot on what feels best to you. Waxed floss is often more comfortable to use, although it can be more difficult to grip with your fingers as it is slightly more slippery than unwaxed floss.

The coating is either beeswax or a Teflon coating. For vegans, only the latter is an option in this case. Some flosses are also coated with additives such as fluoride and chlorhexin. These substances are found in toothpaste and they are supposed to harden the enamel and thus protect the tooth from decay.

However, the concentration of these additives on dental floss is so low that they have little effect.

You can find out which floss suits you best by trying it out.

Scope of delivery

Depending on how often you plan to floss your teeth, it may be a good idea to buy larger quantities, as the price per piece is usually lower. If you plan to floss daily, as recommended, a 50-metre floss pack will last about 100 to 125 days.

A piece of floss should be between 40 and 50 centimetres long. A pack of 50 pieces of Superfloss will only last 50 days.

In the beginning, however, it is advisable to buy only one pack so that you can try out which floss is best for you and to avoid buying the wrong one.

Proper dental hygiene is crucial for a particularly bright smile. Along with the right toothbrush and toothpaste, this includes good dental floss. This will give you an all-round clean and radiant smile. (Photo: maridav / 123RF.com)

Facts worth knowing about flossing

Can I make my own dental floss?

If you want to live plastic-free, you can also make your own dental floss. Take a piece of silk and separate the individual threads. Then twist them together and use them as dental floss, as described above.

What are the alternatives to dental floss?

Interdental brushes are also suitable alternatives for interdental care. However, they are thicker than floss and not suitable for people with small interdental spaces.

You can also buy oral irrigators that use a jet of water to clean your interdental spaces.
