Brushing teeth is something most of us have done since childhood — which is precisely why so many people do it incorrectly. A habit formed in early life, often without much guidance beyond “brush twice a day”, can persist for decades with technique flaws that slowly erode gum health and enamel without the person ever realising. Dental hygienists see the consequences of poor brushing and flossing every day, and the most common issues they encounter are entirely preventable. Whether you book a regular hygienist appointment or have not seen a hygienist in years, refining your home routine is the single most powerful thing you can do for your long-term oral health.
Choosing the Right Toothbrush
Before getting into technique, it is worth addressing the tool itself. Dental hygienists generally recommend a soft or extra-soft bristled brush — not medium or firm. Harder bristles do not clean more effectively; they simply cause more damage to enamel and gum tissue over time. This applies whether you use a manual or electric toothbrush.
Electric toothbrushes — particularly oscillating-rotating models — are consistently shown in clinical research to outperform manual brushes in terms of plaque removal and gum health improvement. They do much of the mechanical work for you, require less correct technique, and often include pressure sensors and timers. If you are using a manual brush, however, excellent results are entirely achievable with proper technique and discipline.
Replace your toothbrush or electric brush head every three months, or sooner if the bristles are visibly worn or splayed. Worn bristles are significantly less effective at cleaning teeth and can harbour bacteria.
The Correct Brushing Technique Step by Step
Apply a pea-sized amount of fluoride toothpaste — adults should use a paste with at least 1,350 ppm fluoride, as recommended by the NHS. Spit after brushing but do not rinse with water, as this washes away the protective fluoride before it has had time to work.
- Hold the brush at a 45-degree angle to the gumline, so that the bristles sit partly on the tooth and partly on the gum
- Using light pressure, make small circular or short back-and-forth strokes along the gumline and tooth surface
- Work systematically around the mouth — divide into four quadrants (upper left, upper right, lower left, lower right) and spend at least 30 seconds on each
- Clean the outer surfaces of all teeth, then the inner surfaces, then the chewing surfaces
- For the inner surfaces of front teeth, tilt the brush vertically and use gentle up-and-down strokes
- Brush for at least two minutes in total — use a timer if you are not confident about this
- Brush your tongue to remove bacteria and freshen breath
The most commonly missed areas are the backs of the lower front teeth (where tartar builds up rapidly), the gumline on the inner surfaces of back molars, and the very last teeth at the back of the mouth. Make a conscious effort to reach these zones.
How to Floss Correctly
Flossing cleans the approximately 40% of each tooth’s surface that lies between adjacent teeth — surfaces that a toothbrush simply cannot reach. It should be done at least once a day, ideally before brushing so that any dislodged debris is then swept away.
- Take around 45 cm (18 inches) of floss and wind most of it around the middle fingers of each hand, leaving about 3–5 cm to work with
- Hold the floss taut between thumbs and index fingers
- Gently slide it between teeth using a zig-zag motion — do not snap it down into the gum
- Curve the floss into a C-shape around each tooth and slide it gently under the gumline as well as along the tooth surface
- Use a clean section of floss for each tooth
- Do not forget the back surfaces of the last molars on each side
If flossing is new to you, or you have not done it consistently, expect some bleeding for the first week or two. This indicates gum inflammation from accumulated plaque — it is not a reason to stop. With consistent daily flossing, bleeding should resolve as gum health improves.
Interdental Brushes: Often Better Than Floss
For many adults, interdental brushes (small bottle-brush shaped tools that fit between teeth) are actually more effective than floss at cleaning interproximal spaces. They are easier to use, cover more surface area, and are particularly well-suited to people with wider gaps between teeth, gum recession, or any crowns, bridges, or implants.
Interdental brushes come in a range of sizes, measured by the diameter of the brush head in millimetres. You may need different sizes for different parts of your mouth. Your hygienist can help you identify the correct sizes during an appointment and demonstrate the technique. The key points are:
- Insert the brush gently between teeth without forcing it
- Move it back and forth several times
- Do not bend or angle the brush as this can damage the gum tissue
- Rinse the brush after each space and replace the brush when bristles are worn
Mouthwash: Where It Fits In
Mouthwash is a useful adjunct to brushing and flossing — but not a replacement. A fluoride mouthwash used at a different time to brushing (for example, after lunch) provides an additional fluoride boost for enamel protection. Antibacterial mouthwashes containing chlorhexidine can be useful in the short term for managing gum inflammation, but are not recommended for indefinite daily use as they can stain teeth and affect the balance of oral bacteria.
Do not use mouthwash immediately after brushing — rinse away your toothpaste and you lose the fluoride benefit. Use it at a separate time of day instead.
Brushing and Flossing: A Side-by-Side Summary
| Element | Brushing | Flossing / Interdental Cleaning |
|---|---|---|
| Frequency | Twice daily | Once daily |
| Duration | 2 minutes minimum | 2–3 minutes (all gaps) |
| Best time | Morning and last thing at night | Before your evening brush |
| Pressure | Light (no hard scrubbing) | Gentle; never snap or force |
| Tool recommendation | Soft-bristled electric or manual brush | Interdental brushes or floss (hygienist can advise) |
| Do not | Rinse with water after brushing | Skip because gums bleed slightly |
Common Mistakes Hygienists See Every Day
- Brushing immediately after eating acidic food or drinks — wait 30 minutes to allow enamel to reharden before brushing
- Brushing side to side with hard pressure — causes enamel abrasion and gum recession
- Snapping floss down onto the gum — traumatises the gum tissue and puts many people off flossing permanently
- Using the same section of floss throughout — redeposits bacteria between teeth rather than removing them
- Only brushing the fronts of teeth — tartar build-up is heaviest on the inner surfaces of lower front teeth and the outer surfaces of upper back teeth
- Skipping the last tooth on each side — the very back molars are particularly vulnerable to decay and gum disease when missed
The Role of Professional Hygiene Visits
Even with perfect home care, professional cleaning remains important. Tartar — hardened plaque — can only be removed with professional instruments, and even the most diligent brusher will accumulate some. The NHS provides detailed guidance on how to keep your teeth clean, and it is well worth reviewing if you want to ensure your home routine is as effective as possible.
A hygienist appointment also provides the opportunity for a professional to identify early warning signs of gum disease or enamel wear before they develop into more significant problems — and to offer personalised advice based on what they can actually see in your mouth rather than generic guidance.
At Tarbert Dental Surgery, we are always happy to spend time during your hygienist appointment going through brushing and flossing technique in a hands-on, practical way. We find that most patients benefit from even small adjustments to their routine, and these adjustments often make a visible difference to gum health within a few weeks. If you would like to book an appointment or simply get some advice, give us a call on 01880 820387 — we would be very glad to help.
