You have been brushing your teeth your entire life. That does not mean you have been doing it well. Most adults learned their brushing technique as children and have not updated it since. The result is decades of a habit that may be leaving plaque behind, damaging gum tissue, or missing key surfaces entirely.
This is not a patronising refresher. It is a practical guide based on what dentists and hygienists see every day in clinical practice: the spots that are always missed, the mistakes that cause problems, and the technique that produces the right results.
The correct technique (modified Bass method)
The modified Bass technique is the one most dental professionals recommend. It targets the gum line, where plaque accumulates and where gum disease begins.
Step 1: Position the brush. Hold your toothbrush at a 45-degree angle to the gum line. The bristle tips should be pointing partly into the gum sulcus (the small groove where the gum meets the tooth).
Step 2: Use short, gentle strokes. Move the brush in small circular or vibrating motions, covering one to two teeth at a time. Do not scrub back and forth across multiple teeth. The goal is to dislodge plaque from the gum line, not to polish the tooth surface.
Step 3: Sweep away from the gum. After vibrating at the gum line, roll the brush head away from the gum toward the biting surface of the tooth. This sweeps loosened plaque off the tooth.
Step 4: Cover all surfaces. Every tooth has three accessible surfaces: the outer (cheek) side, the inner (tongue) side, and the biting or chewing surface. All three need brushing. Most people are thorough on the outer surfaces and neglect the inner surfaces, particularly on the lower front teeth.
Step 5: Brush the inside of front teeth vertically. For the inner surfaces of your upper and lower front teeth, tilt the brush vertically and use the toe (tip) of the brush head with the same gentle vibrating motion.
Step 6: Brush chewing surfaces. Use a back-and-forth motion on the flat biting surfaces of your molars and premolars where grooves trap food and bacteria.
Step 7: Brush your tongue. Gently brush the surface of your tongue from back to front to remove bacteria and reduce bad breath.
Total time: 2 minutes. Divide your mouth into four quadrants (upper right, upper left, lower right, lower left) and spend 30 seconds on each.
Common mistakes
Brushing too hard
Harder is not better. Aggressive brushing wears away enamel over time and causes gum recession. Receded gums expose the root surface, which is softer than enamel and more vulnerable to decay and sensitivity.
Use a soft-bristled brush and gentle pressure. If your bristles splay out within a month, you are pressing too hard.
Using the wrong brush
A toothbrush with hard bristles does more harm than good. The Australian Dental Association recommends a soft-bristled brush for most adults. The head should be small enough to reach your back teeth comfortably.
Whether you use manual or electric is less important than technique, though electric toothbrushes with oscillating or sonic heads tend to remove more plaque with less effort.
Rushing
The average adult brushes for about 45 seconds. That is less than half the recommended two minutes. Set a timer. Use an electric brush with a built-in timer. Play a short song. Whatever works to keep you going for the full two minutes.
Neglecting the gum line
If you are brushing the middle of the tooth and missing the gum line, you are missing the area where plaque does the most damage. Gum disease starts at the gum line, not on the visible surface of the tooth. Angle your bristles into the gum margin.
Skipping the inner surfaces
The inner (lingual) surfaces of teeth, the side facing your tongue, collect plaque just like the outer surfaces. Lower front teeth are particularly prone to tartar buildup on the inner side because a salivary duct opens nearby. Tilt the brush vertically and clean these surfaces with care.
Brushing right after eating acidic food
Acidic foods and drinks (citrus fruits, juice, soft drinks, wine) temporarily soften tooth enamel. Brushing immediately after can abrade the softened surface. Wait 30 minutes, or rinse your mouth with water first to neutralise the acid.
How to choose a toothpaste
Look for a toothpaste that contains fluoride (at least 1,000 ppm for adults). Fluoride strengthens enamel and helps prevent cavities. Beyond that, the brand and flavour matter less than using the right technique.
If you have specific concerns:
- Sensitivity: A desensitising toothpaste containing potassium nitrate or stannous fluoride can reduce sensitivity over time.
- Staining: Whitening toothpastes contain mild abrasives that remove surface stains but will not change the underlying tooth colour.
- Gum disease risk: Your dentist may recommend a toothpaste with stannous fluoride, which has antibacterial properties.
Avoid charcoal toothpastes. They are abrasive, often lack fluoride, and there is no strong evidence that they whiten teeth more effectively than standard fluoride toothpaste.
When to replace your toothbrush
Replace your manual toothbrush or electric brush head every 3 months. Replace it sooner if the bristles are frayed, bent, or discoloured. A worn brush does not clean effectively.
Also replace your brush after recovering from an illness, particularly a respiratory infection or oral thrush.
Brushing alone is not enough
Even excellent brushing technique does not reach between your teeth. The contact points where teeth touch each other harbour plaque that a toothbrush cannot access. This is why flossing or interdental brushes are a necessary addition, not an optional extra.
A complete daily routine looks like this:
- Brush for 2 minutes, twice a day (morning and night)
- Clean between teeth once a day with floss, interdental brushes, or a water flosser
- Use a fluoride toothpaste
- Spit the toothpaste out after brushing but do not rinse, so the fluoride stays on your teeth longer
When to see a professional
Even with excellent home care, professional dental check-ups and cleans are needed every six months. Your dentist and hygienist can remove hardened plaque (tartar) that brushing cannot, identify early problems, and give you feedback on any areas your technique is missing.
At Ivy Dental in Everton Park and Nundah, we show patients where they are missing during their clean so they can adjust their technique at home. Small changes in brushing habits can make a measurable difference at your next visit.
