The ‘flossophy’ of interdental cleaning
Everybody knows the importance of a good routine when cleaning teeth; however, toothbrushing alone isn’t sufficient enough to maintain healthy teeth and gums.
This article aims to educate you on the significance of interdental cleaning, giving you the tools, and an understanding of the correct method.
Don’t forget to learn how to brush your teeth correctly!
What is interdental cleaning
Simply put, it is cleaning between your teeth.
Why interdental cleaning is important
If you imagine your tooth, it has 5 surfaces: the inside, the outside, the biting surface and the two side surfaces. Even by using the correct toothbrushing method, you can only achieve the effective cleaning of the first three surfaces listed above.
That leaves the two side surfaces of the teeth unattended, which provides ideal circumstances for the plaque to sit there all the time. Just to recap, plaque is a major causative factor for gum disease (which if left untreated could lead to tooth loss) and contributes to the development of caries (tooth decay).

When the plaque sits on the teeth, the bacteria (and their by-products) trigger an inflammatory response in the gums (gingivitis and/or periodontal disease develops) As a result they swell and ‘pockets’ appear. This means that the gum detaches itself from the tooth and it gives way to the bacteria to travel further down on the side of the tooth.
The bacteria and the by-products (toxins) and the body trying to fight off those are causing damage not just to the gums but the bone around the tooth as well. This destruction of the supporting tissues will lead to mobile teeth and eventually tooth loss.
If this wouldn’t motivational enough, maybe it is worth considering the effect gum disease can have on your overall health (please read one of my previous articles to recap: Links between general and oral health).
The purpose of interdental cleaning is to prevent that by removing the plaque from between the teeth. Ideally, interdental cleaning needs to be done once a day (or more, if it is advised by your dental care professional).

Interdental cleaning aids
Interdental cleaning aids are available in various forms, including:
- interdental brushes
- water jets
- dental floss
- rubber tips
All of these options have advantages and disadvantages.
Dental floss is a soft, thin cord.
It comes in various types (waxed, unwaxed, tape, and super floss). Floss is available as a roll of string, but you can buy disposable floss picks/flossers (the floss is stretched out on a plastic holder) as well.
Tips for flossing
String floss
- Take about 18 inches/45cm of floss from the roll.
- Wrap it around both your middle fingers in a way that when you hold the floss with your index finger and thumb there will be about 2 inches/5cm of floss in-between.
- Your index finger and thumb will manoeuvre the floss between your teeth (wrapping it around the middle finger will stop the floss from sliding, as it isn’t easy to have a firm grip on it).
- Slide the floss with gentle seesaw-like motions through the contact point of the teeth (don’t rush it, as you can hurt your gums if you push it down with too much force).
- Once it is between the teeth create a C-shape against the wall of the tooth on one side and move the floss up and down (make sure you go under the gumline, but just until you hit the natural resistance of your gums; forcing it further down can cause damage).
- Do the same on the other side of the gap.
- Use a new, clean section of the floss when you move to the next two teeth (to make sure you are not redistributing plaque/bacteria from one tooth onto another).
Effective flossing could be difficult to master as it is quite technique sensitive. Floss picks are easier to use, however, the disadvantage is that you will use the same piece of floss between all your teeth (it would be very expensive to use multiple flosses picks for one session, furthermore very bad for the environment due to the plastic waste they create).
Remember!
You have to clean every wall of every tooth (e.g. the back wall of the last standing tooth).
Did you know?
If you use the string floss and it gets stuck don’t try to yank it upwards (you can dislodge a filling or a crown, or shred the floss), just let it go to one side and pull it through. If this happens too often it might be worth trying to use dental tape instead, which is flatter than the floss, therefore it can slide through the contact points of the teeth easier.
Interdental brushes
are little brushes attached to a plastic holder (they look like miniature bottle brushes). They come in different sizes and with different types of holders. They are easier to use than string floss.
Tips for use
- Choose the right size of brush for the different gaps (there are various sizes of gaps between the teeth in a mouth). Ideally, the brush should fit snugly without having to force it in, but also effectively clean the walls of the teeth on both sides of the gap.
- Insert the brush gently and move it back and forth a few times.
- Make sure you clean every gap in your mouth.
- Ensure that you wash the brush before inserting it into the next gap (you don’t want to transfer the plaque from one place to another) and when you are finished. It is ideal to leave them to dry, before putting them away.
Did you know?
The most popular make is TePe. You have to bear in mind that different makes have different colour coding systems for the different sizes (e.g. pink TePe might not be the same size as the pink version of another make).
Electric flossers
Simply put these are devices, which are operated by pumping either air or water through a flosser tip. The cleaning between the teeth is achieved by the power of the air jet or water flow. Some makes need to be recharged before use; others have to be plugged in while using them. Electric flossers are easier to use than floss, and as they have a fairly big handle, they can be helpful for people with limited manual dexterity (e.g. people suffering from arthritis in the hand). The disadvantage is that they are costly. Also, some dental professionals are doubtful whether they are as efficient as other interdental cleaning aids.
These are just the most commonly used interdental cleaning aids. Some people may only need to use one type of interdental cleaning aid; others (who have more complex dental needs, e.g. having crowns, bridges, implants or orthodontic appliances fitted) may have to use a wider variety of products.
The market is full of different types of interdental cleaning aids and it can be very confusing, which one to choose. The condition of people’s oral health differs widely, hence their oral health care needs will vary individually. It is advisable (before spending money and finding the product doesn’t have the right effect) to consult your dentist/hygienist. They will provide the best advice based on the condition of the teeth/gums what interdental aids to purchase and how to use them.
At present, the only way to achieve good oral health is to put the time and effort in (i.e. there is no easy way around it) by using the correct toothbrushing and interdental cleaning technique and visiting the dentist regularly and the hygienist (if instructed by the dentist). However, if you look at the benefits, it is worth it.
Finally, to quote one of my dental colleagues: ‘Clean daily between the teeth, you want to keep!’
