What Is Dental Floss and How Does It Help Your Teeth?

 

Looking after the spaces between your teeth is just as important as brushing. A toothbrush — no matter how well you use it — simply cannot reach the tight gaps between teeth or clean beneath the gumline effectively. That is where dental floss comes in. Oral-B Pro-Expert Premium Floss is a waxed, shred-resistant floss designed to glide smoothly between teeth, removing plaque and food debris from areas your brush misses entirely. At just £3.49, it is one of the most cost-effective steps you can take for your oral health. You can find it alongside other products in our oral health collection.

The NHS recommends cleaning between your teeth every day using floss or an interdental brush. Skipping this step means leaving plaque undisturbed in areas where tooth decay and gum disease most commonly begin. Regular interdental cleaning has been shown to reduce gingival inflammation and support healthier gums over time.

 

How Does Oral-B Pro-Expert Premium Floss Work?

 

The mechanism is straightforward but clinically meaningful. Plaque is a sticky biofilm of bacteria that accumulates on tooth surfaces throughout the day. When it builds up between teeth and along the gumline, it can trigger inflammation of the gums — known as gingivitis — and, if left untreated, progress to more serious periodontal disease. Flossing physically disrupts this biofilm before it can harden into tartar.

  • The waxed coating allows the floss to slide easily through tight contacts without snapping or shredding.
  • The floss wraps around the curved surface of each tooth in a C-shape, maximising contact with the tooth and gum margin.
  • Gentle up-and-down strokes dislodge food particles and disrupt the plaque layer.
  • Using a fresh section of floss for each tooth prevents redistributing bacteria from one gap to another.

 

Who Should Use Oral-B Pro-Expert Premium Floss?

 

This floss is suitable for most adults and older children who can manage the technique safely. It is particularly well suited to people with tightly spaced teeth, where interdental brushes may not fit comfortably. If you have been told by your dentist that you have early signs of gum disease, or if you simply want to maintain good oral hygiene between check-ups, daily flossing is a sensible habit to build.

  • Adults wanting to reduce plaque build-up between teeth
  • People with tight tooth contacts who find interdental brushes too wide
  • Those with a history of gingivitis or early gum disease
  • Anyone looking to complement their brushing routine with interdental cleaning

 

How Does Oral-B Pro-Expert Premium Floss Compare to Interdental Brushes?

 

Feature Oral-B Pro-Expert Premium Floss Interdental Brushes
Best for tight gaps Yes — slides through narrow contacts Less suitable for very tight spaces
Ease of use Requires some technique Generally easier for beginners
Plaque removal Effective for tight contacts May be more effective for wider gaps
Cost £3.49 per pack Varies; often slightly higher per use

 

Is Oral-B Pro-Expert Premium Floss Suitable for Sensitive Gums?

 

If your gums are sensitive or prone to bleeding, you may be wondering whether flossing will make things worse. In most cases, the opposite is true. Mild bleeding when you first start using dental floss is common and typically settles within one to two weeks as gum health improves. The waxed surface of this floss helps it move gently between teeth, reducing the risk of snapping against the gum tissue. If bleeding persists beyond two weeks, speak to your dentist — it may indicate underlying gum disease that needs professional attention.

This product is not a medicine. However, if you have a dental condition, recent oral surgery, or are taking blood-thinning medicines, speak to your dentist or pharmacist before starting a new flossing routine. You might also find it helpful to explore our dental products collection for complementary oral care items.

Specifications of Oral-B Pro-Expert Premium Floss

 

What Is Oral-B Pro-Expert Premium Floss and What Is It Used For?

 

Oral-B Pro-Expert Premium Floss is a waxed, shred-resistant interdental floss used to clean the spaces between teeth and along the gumline. It is not a medicine — it is a dental hygiene product designed for daily use as part of a complete oral care routine. Its primary purpose is to remove plaque and food debris from areas that a toothbrush cannot reach, helping to prevent tooth decay and gum disease.

The NHS advises that you should clean between your teeth at least once a day, either with floss or interdental brushes. Failing to do so leaves plaque undisturbed in the interdental spaces, where it can cause cavities and trigger gingivitis — the earliest, reversible stage of gum disease. Used consistently, dental floss supports healthier gums, fresher breath, and a lower risk of dental problems over time.

 

What Do You Need to Know Before Using Oral-B Pro-Expert Premium Floss?

 

This product is suitable for most people, but there are a few things worth being aware of before you start.

Contraindications and warnings:

  • Do not use if you have had recent oral surgery — wait until your dentist confirms it is safe to floss the affected area.
  • If you have a dental bridge, implant, or orthodontic appliance, ask your dentist about the correct flossing technique or whether a floss threader is needed.
  • If gum bleeding persists for more than two weeks of regular flossing, consult your dentist as this may indicate gum disease requiring treatment.
  • Children should use floss only under adult supervision and when they have the dexterity to do so safely.
  • If you are taking anticoagulant medicines (blood thinners), speak to your pharmacist before starting a new flossing routine, as gum bleeding may be more pronounced.

Known interactions:

  • No pharmacological drug interactions — this is a non-medicated product.
  • If you use medicated mouthwash or prescription dental gels, continue using them as directed by your dentist alongside flossing.

 

How Should You Use Oral-B Pro-Expert Premium Floss?

 

Technique matters. Using floss incorrectly — snapping it hard against the gums or rushing through the process — can cause unnecessary irritation. Follow these steps for safe, effective interdental cleaning.

  1. Break off approximately 45 cm (about 18 inches) of floss from the dispenser.
  2. Wind most of the floss around the middle finger of one hand and the rest around the middle finger of the other hand, leaving 2–3 cm to work with.
  3. Hold the floss taut between your thumbs and index fingers.
  4. Gently guide the floss between two teeth using a zigzag motion — do not snap it into the gum.
  5. Curve the floss into a C-shape around one tooth and slide it gently beneath the gumline.
  6. Move the floss up and down against the tooth surface to dislodge plaque and debris.
  7. Repeat the C-shape on the adjacent tooth in the same gap.
  8. Use a fresh section of floss as you move to each new gap.
  9. Rinse your mouth with water or mouthwash after flossing.
Indication Age Group Frequency Notes
Daily plaque removal Adults Once daily Ideally before brushing at night
Daily plaque removal Children (with supervision) Once daily When adjacent teeth are touching and child has sufficient dexterity

If you are new to flossing, it is worth exploring our dental products range for additional tools such as floss picks or interdental brushes that may help you build the habit.

 

What Are the Possible Side Effects of Oral-B Pro-Expert Premium Floss?

 

Because this is a non-medicated product, it does not carry the same side effect profile as a medicine. However, some people do experience minor issues when they first start flossing regularly.

Common side effects (especially in the first 1–2 weeks):

  • Mild gum bleeding — very common when starting out; usually resolves as gum health improves
  • Temporary gum tenderness or sensitivity
  • Minor discomfort when guiding floss through tight contacts

Less common side effects:

  • Gum soreness if too much pressure is applied
  • Slight gum recession if floss is repeatedly snapped hard against the gum tissue

These issues are almost always technique-related. Using gentle, controlled movements and curving the floss around each tooth rather than forcing it straight down will significantly reduce the risk of irritation.

 

How Should You Store Oral-B Pro-Expert Premium Floss?

 

Proper storage keeps the floss in good condition and ensures it remains hygienic between uses.

  • Store at room temperature, away from direct sunlight and excessive heat.
  • Keep the dispenser in a dry place — avoid leaving it in a steamy shower area where moisture could affect the floss.
  • Keep out of reach of young children to prevent accidental ingestion or entanglement.
  • Do not use if the floss appears discoloured, frayed before use, or has an unusual odour.
  • Check the expiry date on the packaging before use.

Good oral hygiene goes hand in hand with overall health. If you are also managing other aspects of your wellbeing, you might find our vitamins and supplements collection a useful complement to your daily routine.

How does dental floss remove plaque between teeth?

Dental floss works by physically disrupting the plaque biofilm that accumulates in the tight spaces between teeth where a toothbrush bristle cannot reach. When you guide the floss in a C-shape around each tooth and move it up and down, it scrapes away bacteria and food debris from the tooth surface and just beneath the gumline. This mechanical action is what makes flossing such an important complement to brushing.

How do I use Oral-B Pro-Expert Premium Floss step by step?

Break off around 45 cm of floss and wind most of it around your middle fingers, leaving a short working section. Gently guide it between each pair of teeth using a zigzag motion — never snap it into the gum — then curve it into a C-shape around each tooth and slide it just beneath the gumline. Use a clean section of floss for each gap and rinse your mouth afterwards.

When is the best time to use dental floss?

The NHS recommends flossing once a day, and many dental professionals suggest doing so before you brush your teeth at night. Flossing first loosens plaque and debris between teeth, allowing fluoride toothpaste to penetrate those spaces more effectively when you brush afterwards. Consistency is more important than the exact time of day — pick a time that fits your routine and stick to it.

Is it normal for my gums to bleed when I start flossing?

Yes, mild gum bleeding when you first start flossing is very common and is usually a sign that your gums are inflamed from plaque build-up rather than a sign that flossing is harmful. In most cases, bleeding settles within one to two weeks as your gum health improves with regular cleaning. If bleeding continues beyond two weeks, book an appointment with your dentist as it may indicate gingivitis or another condition that needs attention.

Who is Oral-B Pro-Expert Premium Floss suitable for?

This floss is suitable for most adults and older children who have the dexterity to use it safely. It is particularly well suited to people with tightly spaced teeth where interdental brushes may not fit comfortably. People with dental bridges, implants, or braces should ask their dentist about the correct technique or whether a floss threader is needed before using standard floss.

Can I use this floss if I have a dental bridge or braces?

You can floss with a bridge or braces, but you will likely need a floss threader to guide the floss beneath the bridge wire or between brackets. Standard floss cannot pass through these structures without a threader. Ask your dentist or orthodontist to demonstrate the correct technique for your specific appliance before you start.

What are the alternatives to Oral-B Pro-Expert Premium Floss?

Common alternatives include interdental brushes, floss picks, and water flossers. The NHS notes that interdental brushes may be more effective than floss for people with larger gaps between teeth, while floss tends to work better for tight contacts. The right choice depends on your individual dental anatomy — your dentist can advise which option suits you best. You can browse a range of options in our dental products collection.

How long can I use dental floss as part of my daily routine?

Dental floss is safe for lifelong daily use and is recommended as a permanent part of your oral hygiene routine by the NHS. There is no maximum duration — in fact, the longer you maintain the habit, the greater the cumulative benefit to your gum health and the lower your risk of tooth decay in the interdental areas. Think of it as a daily investment in your long-term dental health.

Does flossing actually prevent gum disease?

Yes. Regular interdental cleaning disrupts the plaque that causes gingivitis — the earliest, reversible stage of gum disease — before it can harden into tartar and trigger more serious periodontal disease. The NHS recommends daily interdental cleaning alongside twice-daily brushing as the foundation of good oral hygiene. Consistent flossing, combined with regular dental check-ups, significantly reduces your risk of developing gum disease.

What happens if I floss too hard or too aggressively?

Flossing too aggressively — particularly snapping the floss hard into the gum — can cause gum soreness, irritation, and over time may contribute to minor gum recession. Always use gentle, controlled movements and guide the floss carefully between teeth rather than forcing it. If you find the technique difficult, a floss pick or interdental brush may be easier to control while you build confidence.

Is Oral-B Pro-Expert Premium Floss waxed or unwaxed?

Oral-B Pro-Expert Premium Floss is a waxed floss, which means it has a smooth coating that helps it glide more easily through tight contacts between teeth without shredding or snapping. Waxed floss is generally recommended for people with closely spaced teeth or those who are new to flossing, as it tends to be easier to manoeuvre. Unwaxed floss can be slightly thinner but may fray more easily in tight spaces.

What are the latest recommendations on flossing from dental experts?

Current NHS guidance continues to recommend daily interdental cleaning as an essential part of oral hygiene, alongside twice-daily brushing with a fluoride toothpaste. NICE guidance on dental recall also supports regular interdental cleaning as a preventive measure against gum disease and tooth decay. While some studies have debated the strength of evidence for flossing specifically, clinical consensus remains that removing plaque from between teeth daily is beneficial.

How should I store Oral-B Pro-Expert Premium Floss?

Store the floss dispenser at room temperature in a dry location, away from direct sunlight and steam — so avoid leaving it on the edge of a shower or bath where humidity is high. Keep it out of reach of young children to prevent accidental ingestion or entanglement. Check the expiry date on the packaging and do not use the floss if it appears discoloured or has an unusual texture.

Can children use Oral-B Pro-Expert Premium Floss?

Children can use dental floss once adjacent teeth are touching and they have sufficient dexterity to manage the technique safely — typically from around age seven or eight, under adult supervision. Younger children may find floss picks easier to handle than traditional floss on a spool. The NHS recommends that parents help children with interdental cleaning until they are confident doing it independently, usually around age ten to twelve.

How Should You Use Oral-B Pro-Expert Premium Floss?

Using dental floss correctly makes a real difference to how effective it is. Rushing through the process or using the wrong technique can mean you miss plaque entirely — or worse, irritate your gums unnecessarily. Take a moment to follow these steps each time you floss, and it will quickly become second nature.

Follow this step-by-step guide for safe and effective interdental cleaning:

What Is the Correct Dose of Oral-B Pro-Expert Premium Floss?

There is no "dose" in the medicinal sense, but using the right amount of floss and the right frequency is important for effective cleaning. Using too little floss means you cannot maintain a clean working section as you move between teeth.

When Is the Best Time to Use Oral-B Pro-Expert Premium Floss?

The NHS recommends flossing once a day, and the most beneficial time is generally before your evening brush. Flossing first removes the debris and loosens plaque between teeth, allowing your fluoride toothpaste to reach those spaces more effectively when you brush immediately afterwards. That said, the most important thing is consistency — if mornings work better for your routine, flossing then is far better than not flossing at all.

Try to floss at the same time each day to build the habit. Many people find it helpful to keep their floss dispenser next to their toothbrush as a visual reminder.

How Long Can You Use Oral-B Pro-Expert Premium Floss For?

Dental floss is intended for lifelong daily use. Unlike medicines, there is no treatment course or maximum duration — the NHS recommends making interdental cleaning a permanent part of your oral hygiene routine. The longer you maintain the habit, the greater the cumulative benefit to your gum health and the lower your risk of developing tooth decay in the interdental areas.

Replace your floss dispenser when it runs out, and check the expiry date on the packaging. If you notice any change in the texture or appearance of the floss, discard it and open a new pack.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Oral-B Pro-Expert Premium Floss?

Because this is a non-medicated dental hygiene product rather than a medicine, it does not carry a conventional side effect profile. However, some people do experience minor issues — particularly when they first start flossing regularly after a period of not doing so. These are almost always temporary and resolve as your gum health improves.

  • Mild gum bleeding — very common in the first one to two weeks of regular flossing
  • Temporary gum tenderness or sensitivity around the gumline
  • Minor discomfort when guiding floss through tight contacts between teeth

What Are the Less Common Side Effects of Oral-B Pro-Expert Premium Floss?

Less commonly, people experience issues that are usually related to technique rather than the product itself. Using too much force or an incorrect motion can cause unnecessary irritation to the soft tissue around your teeth.

  • Gum soreness or bruising if the floss is snapped hard against the gum
  • Slight gum recession over time if aggressive flossing technique is used repeatedly
  • Temporary tooth sensitivity in areas where the gumline is already receded

What Are the Serious Side Effects of Oral-B Pro-Expert Premium Floss?

Serious side effects from dental floss are extremely rare. However, if you notice persistent or heavy gum bleeding that does not settle after two weeks of regular, gentle flossing, this is not a side effect of the floss itself — it is more likely a sign of underlying gum disease such as gingivitis or periodontitis that requires professional dental assessment. Do not ignore persistent bleeding. Book an appointment with your dentist promptly.

If you experience significant pain, swelling, or signs of infection in the gum tissue, stop flossing the affected area and seek dental advice as soon as possible.

What Should You Do If You Experience Side Effects?

If you experience mild bleeding or tenderness when you first start flossing, continue with a gentle technique and give your gums time to adapt — most people see improvement within one to two weeks. If discomfort is significant, try using less pressure and ensure you are curving the floss around each tooth rather than forcing it straight down into the gum. If symptoms do not improve, speak to your dentist or pharmacist for personalised advice on technique or alternative interdental cleaning methods.

Can Oral-B Pro-Expert Premium Floss Interact With Other Products?

As a non-medicated product, dental floss has no pharmacological interactions with medicines. If you use a medicated mouthwash, prescription dental gel, or fluoride treatment prescribed by your dentist, you can continue using these alongside flossing as directed. In fact, flossing before applying a fluoride treatment or mouthwash may enhance its effectiveness by clearing debris from between teeth first. If you are unsure about the order in which to use your dental products, ask your dentist or pharmacist for guidance.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
