Using dental floss is one of the most overlooked parts of a daily oral-health routine. Brushing matters, of course, but it does not reliably clean the narrow contact points between the teeth. That is where plaque often settles first, where food debris lingers longest, and where gum inflammation can begin quietly. This guide explains why flossing matters, how to choose the right interdental tool, and how to use it properly without turning it into a battle every evening.
Short Answer
Yes, cleaning between your teeth every day is worth it. If your teeth are tightly packed, dental floss is often a sensible choice. If you have wider gaps, an interdental brush may work even better. The goal is not to force everyone into the same product. The goal is to disrupt plaque where a toothbrush cannot reach and to make that habit consistent enough to protect your gums long term.
Why Do We Need to Use Dental Floss?
Brushing cleans the accessible surfaces of the teeth well enough when it is done properly, but it does not fully clean the spaces between them. Those interproximal areas are exactly where plaque likes to build up first. Once bacteria settle there, you can start to see the chain reaction: gum irritation, bleeding, bad breath, tartar, and eventually cavities or periodontal disease.
This is why people can honestly say, “But I brush well twice a day,” and still end up with inflamed gums between the teeth. The missing piece is often interdental cleaning rather than brushing itself. Daily flossing is not just a cosmetic habit. It is one of the simplest ways to lower plaque retention in the part of the mouth that a toothbrush misses most reliably.

Floss vs Interdental Brushes vs Water Flossers
One of the biggest misunderstandings in oral care is the idea that floss is the only “correct” choice for everybody. It is not. The right interdental aid depends on your tooth contacts, gum shape, dexterity, dental work and how likely you are to use the tool consistently.
| Tool | Best suited to | Main strengths | Main limitation |
|---|---|---|---|
| Traditional floss | Tight contacts between teeth | Good plaque disruption in narrow spaces | Technique-sensitive and fiddly for some people |
| Dental tape | Wider contacts and flatter surfaces | Broader contact with the tooth | Can feel bulky in very tight spaces |
| Interdental brushes | Gaps, recession, periodontal maintenance | Often easier and more effective where space allows | Will not fit tight contacts |
| Super floss | Braces, bridges, implants | Useful around fixed dental work | Less convenient for general daily use |
| Water flosser | Adjunct for braces or implants, dexterity issues | Easy to use for some people | Not automatically a full replacement for mechanical plaque removal |
If you have larger spaces between the teeth, an interdental brush may actually be the better tool. If you have very tight contacts, floss is often the most realistic option. Water flossers can help certain patients, especially around braces or implants, but they are best viewed as a useful adjunct rather than a universal answer.
Types of Dental Floss
The floss aisle can look far more complicated than it needs to. Most people do not need the “perfect” product. They need one they can use properly every day without hating it.
- Waxed floss: good for tight contacts because it slides more easily and is less likely to shred.
- Unwaxed floss: thinner and sometimes preferred where contacts are very close, though it may fray more easily.
- Dental tape: broader and flatter, often more comfortable for people with slightly wider spaces.
- Super floss: useful around orthodontic appliances, bridges and some implant restorations because it has a firmer threading end and a spongy middle section.
- Floss picks: convenient for travel or people who struggle with finger-wrapped floss, though they can make it harder to achieve the same careful angle around each tooth.
If you have a bridge, braces, aligner attachments or dental implants, the best option is often a special interdental tool rather than a basic supermarket floss alone. The tool matters, but the bigger question is whether it matches your anatomy.
How to Floss Properly
Traditional floss
- Take roughly 45 to 60 centimetres of floss and wind most of it around your middle fingers, leaving a short working section.
- Guide it gently between the teeth with a small sawing motion. Do not snap it straight into the gum.
- Wrap the floss into a “C” shape against one tooth surface.
- Slide it up and down the side of the tooth, including just under the gum margin.
- Repeat on the neighbouring tooth surface before moving on.
- Use a clean section of floss as you progress around the mouth.
Floss picks
- Hold the pick steadily and insert the floss with a light sawing motion.
- Angle it around one tooth at a time rather than simply pushing in and out.
- Rinse the floss if you are reusing the same section around the mouth.
- Finish by rinsing the mouth or brushing, depending on your routine.
Many people find flossing easier in front of a mirror at first. Once the movement feels automatic, it becomes much quicker. The first week is usually the awkward phase; after that, it tends to feel far less dramatic than people expect.
Braces, Bridges, Implants and Children
Braces and fixed orthodontics
Brackets and wires trap food more easily, which makes interdental cleaning more important rather than less. Super floss, floss threaders and small interdental brushes are often more useful than ordinary floss alone.
Bridges and implants
Standard floss is not always ideal around fixed bridgework or implants. Many patients do better with super floss, implant-safe interdental brushes or a water flosser as an adjunct. If you have had implant treatment, it is worth asking your dentist or hygienist to demonstrate the exact cleaning method for your restoration design.
Children
Once two teeth are in contact, food and plaque can lodge between them. Children usually need help from a parent or carer at first. Keep the routine calm, short and gentle. The aim is not perfection on day one. The aim is familiarity and confidence.
Why Do Gums Bleed When You Floss?
This is one of the most common reasons people stop flossing just when they most need to continue. Mild bleeding at the beginning usually means the gums are inflamed because plaque has been sitting there, not because floss is inherently harming them. With gentle, consistent cleaning, that bleeding often settles over several days as the gums calm down.
What is not normal is heavy bleeding, significant pain, obvious ulceration, or bleeding that simply does not improve after a week or so of proper cleaning. That can point to more established gum disease, poor technique, hormonal changes, or another underlying problem that deserves a dental review.
What the Evidence Actually Says
The public conversation around flossing has become oddly dramatic at times, as though it either changes your life completely or does nothing at all. The truth is more ordinary and more useful. The evidence supports cleaning between the teeth daily, but the best tool depends on the clinical situation.
Official UK guidance still recommends cleaning between the teeth every day with floss or interdental brushes. Reviews of the evidence suggest that flossing alongside toothbrushing may help reduce gingivitis, while interdental brushes may be even more effective where there is enough space for them. Evidence for water flossers is less consistent.
In practice, that means the right question is not “Is floss universally superior?” The right question is “Which interdental aid can I use effectively and consistently for my own mouth?”
Long-Term Benefits and Realistic Limits
Used properly, flossing can support gum health, improve breath, reduce food trapping and lower the risk of plaque sitting undisturbed between the teeth. Over time, that can reduce the likelihood of more expensive restorative work caused by preventable decay or periodontal disease.
- It helps keep gum margins cleaner and calmer.
- It reduces the food retention that contributes to bad breath.
- It supports better hygiene around restorations and orthodontic appliances.
- It may reduce the risk of interproximal decay when combined with fluoride toothpaste and sensible diet control.
But flossing is not a cure-all. It does not replace brushing, fluoride, diet control, hydration, or professional cleanings. It is one piece of a good routine, not the whole routine by itself.

Common Flossing Mistakes
- snapping the floss straight into the gum instead of guiding it gently
- cleaning only the contact point rather than wrapping around the tooth surface
- using the same dirty section of floss around the entire mouth
- flossing only when food gets stuck instead of every day
- forcing floss where an interdental brush would actually be more suitable
- giving up after a few days because the gums bled at the start
Frequently Asked Questions about Flossing
Should I floss before or after brushing?
Either is better than skipping it, but many clinicians prefer flossing before brushing because it removes debris first and leaves fluoride toothpaste a clearer path between the teeth.
How often should I floss?
Once a day is a sensible target for most people. Evening is often the easiest time because it leaves the mouth cleaner overnight.
Can children floss?
Yes. Once adjacent teeth touch, plaque can collect between them. Most children need help from a parent or carer at first.
Are water flossers a full substitute for floss?
Not automatically. They can be helpful, especially around braces or implants, but the best tool depends on the contact spaces and the type of restoration you have.
Why do my gums bleed when I floss?
It often signals plaque-related inflammation rather than “damage” from floss. Gentle daily cleaning usually improves it. If bleeding is heavy or does not settle, book a review.
