What are tooth interspace brushes?

In the comprehensive article Clean Interdental Spaces – How to do it, you will find a lot of information about how important it is to regularly and thoroughly clean the interdental spaces.

A good 40% of the tooth surfaces are located in the interdental spaces.

There are many areas between your teeth that you can’t reach with a regular toothbrush – whether it’s a manual toothbrush or an electric toothbrush.

But it is here that food debris settles, which can subsequently cause tooth decay and gum problems.

Surely you are also familiar with the situation that after eating meat or soft sweets, the crevices between the teeth are stuck together or food debris gets stuck there.

Interdental brushes help you safely and thoroughly remove these impurities. They are also convenient for braces wearers, as you can guide the small brushes under the wires of fixed braces.

How are the brushes constructed?

Interdental toothbrushes, also known as interdental brushes, consist of a plastic handle and a wire to which more or less soft bristles are attached.

Wires and bristles come in different diameters to account for the different sized spaces between teeth.

  • The small brushes can be most closely compared to bottle brushes.
  • The bristles can either be evenly shaped or fir tree-shaped from wide to pointed.

When cleaning, insert the wire with the bristles into the interdental space and move them slightly back and forth. This loosens food debris, plaque and plaque.

You can find out how many advantages this type of additional tooth cleaning offers in the article Interdental brushes: the thorough alternative to dental floss. You will find a lot of detailed information about interdental brushes and how to use them.

What should you look out for?

The most important feature of dental interdental brushes is their size.

  • If the brushes are too thick, they will be difficult to insert and may also harm your gums.
  • If the interdental brushes are too thin, you must be careful to actually clean both sides of the crevice.

If you experience bleeding gums, be sure to switch to a smaller size.

Ideal is when the interdental brush can be inserted into the interdental space without much pressure.

To avoid injury, I advise you to start with a very small size for your first attempts. If you find that you can clean between all your teeth with the smallest size without any problems and without exerting pressure, you should try the next larger size.

Repeat this process until you find the ideal size for your interdental space brush.

There are also sets of interdental brushes of different sizes from some suppliers. These are handy for getting started by trying out which brush is best for your teeth.

Tip: If the width of your interdental spaces varies greatly, consider using different brushes.

How often should you use the brushes?

Dentists recommend thoroughly cleaning the spaces between your teeth at least once a day. However, it is better after every meal.

In addition, you can use interdental brushes whenever you notice food debris between your teeth. You’ll be surprised how quickly you get used to the clean interdental spaces and notice any food debris as a foreign object.

You should use the interdental brushes without toothpaste. After cleaning the interdental spaces, you can brush your teeth as usual. Thus, the fluorine-containing pasta also reaches the cleaned interdental spaces.

A subsequent mouth rinse is also recommended.

Who should use interdental brushes?

Actually everyone, after all, good oral hygiene can’t start early enough.

Purchase recommendations tooth interdental brushes

To help you choose the right interdental brush, I ordered several current models online and tried them out for you.

From the findings, I have compiled these three recommended purchases for you.

Alternatives to interdental brush

In principle, there are three effective means to clean the interdental spaces. In addition to interdental brushes, these are dental floss and oral irrigators. Each cleaning practice offers advantages and disadvantages

Dental floss

When flossing, it’s important to develop the right technique to thoroughly clean the spaces between your teeth

Dental floss and interdental brushes

While some people do well with flossing right off the bat, others have trouble inserting it into the spaces between their teeth.

Tip: In these articles you will find a great deal of details, tests and purchase recommendations for dental floss: dental floss at a glance and dental floss in test.

Spangled wearers usually have problems with dental floss. Here, tooth space brushes are therefore often the better choice.

As an advantage, floss cleans the entire tooth surface. With interdental space brushes, the upper, more densely packed tooth walls sometimes remain uncleaned.

Flossettes

To be precise, flossettes are also dental floss, but a handle makes them easier to use.

Interdental brushes and flossettes

For people who have trouble flossing, flossettes are a good alternative.

Read this overview on flossettes to learn many details about the pros and cons of this cleaning technique.

Mouthwashes

Mouthwashers use a jet of water, making them especially gentle on teeth and gums.

oral irrigator or interdental brush

An oral irrigator is a very effective alternative to interdental brushes. If an oral irrigator is an option for you, it’s best to take a look at the WaterPik WP 660.

In comparison, however, oral irrigators are significantly more expensive than the other variants for cleaning the interdental spaces. In addition, oral irrigators also require significantly more space.

Info: If you are interested in oral irrigators, I recommend this detailed test of current oral irrigators.

Which one is the best?

In principle, it is first important to start by cleaning the spaces between your teeth. No matter which of the presented methods you use, anything is better than no cleaning.

alternative to interdental brush

Alternatives to interdental brushes abound: Dental floss, flossettes, oral irrigators. It is important that you also combine cleaning with mouthwashes and, at best, an electric toothbrush. These are much more thorough than ordinary manual toothbrushes.

Which cleaning method is actually the best for you depends largely on the given conditions. People with sensitive gums usually swear by oral irrigators.

With interdental spaces of different sizes, flossing offers very effective cleaning. However, you need to know how best to use the floss.

  • Interdental space brushes are very easy to use, but you must be careful here and use the right size.
  • If you have different sized interdental spaces, it is advisable to use different sizes of brushes.

In general, it is not possible to recommend one of the possible cleaning methods.

Since dental floss and interdental brushes are very cheap to buy, I recommend that you try these two variants first. You will quickly notice which cleaning method suits you best.

Conclusion: cleaning the interdental spaces is important

Only if you also clean the interdental spaces, you can effectively prevent diseases, tooth decay and gum problems. Tooth interdental brushes are a very effective and inexpensive means for this purpose
