Vous hésitez entre brosse manuelle et électrique ? La bonne nouvelle: les deux peuvent bien fonctionner si la technique et la régularité sont au rendez-vous. La science montre toutefois un avantage mesurable aux brosses électriques pour réduire plaque et gingivite, ce qui en fait un bon choix pour de nombreuses personnes, notamment si le contrôle de plaque est difficile ou si les gencives sont sensibles.

Electric vs. Manual: What Does the Evidence Say?
The Cochrane reviews conclude that electric toothbrushes reduce plaque more (≈ 11% at 1–3 months; ≈ 21% after 3 months) and gingivitis (≈ 6% at 1–3 months; ≈ 11% after 3 months) compared to manual ones. Oscillating-rotating models are often the best documented. In practice: they primarily help those who struggle to brush effectively, who wear braces, or who have gingivitis.
Choosing According to your Situation
Babies and Children: Smaller head, easy-to-hold handle. Autonomy develops around 6–7 years old (always under supervision). A simple guideline: if they can tie their shoelaces, they have the coordination to brush correctly.
Orthodontic Appliances (Braces): Opt for an orthodontic brush with a central groove (which surrounds the brackets and goes around the wire) and supplement daily with interdental brushes under the wire. For difficult areas (around attachments, near the gumline, behind molars), add a single-tuft brush for precise cleaning with micro-movements without applying pressure.
DentalGeneva Tip
Discuss it during a consultation in Geneva, and we’ll show you the correct technique!
Sensitive Gums, Implants, Post-Surgery: Opt for extra-soft bristles or a sulcular brush (finer) to limit irritation.
Adults without specific issues: Choose soft bristles as standard: customize your choice according to your gums and technique.
Head, Bristles, and Ergonomics: Key Pointers
A small head better accesses molars. Prefer rounded bristle tips (gentler on enamel and gums). Avoid hard bristles (risk of abrasion and recession). If you opt for an electric toothbrush, let the head work without scrubbing, surface by surface, for a few seconds on each area.
Brushing Technique: 2 Minutes, Twice a Day
La base qui fait la différence: deux brossages quotidiens de 2 minutes, surtout le soir au coucher, avec un dentifrice fluoré. La technique Bass modifiée (inclinaison 45°, petits mouvements près du sillon gingival, puis balayage) est une valeur sûre. Les brosses électriques aident grâce au minuteur et parfois au capteur de pression. Après avoir recraché, ne rincez pas à grande eau: vous gardez le fluor plus longtemps sur les dents.
Did You Know?
The ideal pressure for brushing your teeth is like holding an orange in the palm of your hand 🍊. Imagine this gentle, light weight: that’s exactly the force you should apply to your brush, no more!

Completing your Brushing: between Teeth and Tongue
Brushing does not clean between teeth. Add daily interdental cleaning: dental floss (or floss threaders under bridges/implants), interdental brushes when space allows. A tongue scraper more effectively reduces deposits on the tongue (often useful in cases of halitosis). Water flossers can help if flossing is difficult, but they do not remove all biofilm: they are a supplement.
When to Replace your Brush / Brush Head?
Every 3–4 months, or sooner if the bristles are frayed: a worn brush cleans significantly less effectively. Take advantage of calendar reminders or brush head packs to stay regular. It is advisable to replace your toothbrush after the flu, a cold, tonsillitis, or any viral/bacterial infection. Germs can remain on the bristles for a few days, and even if it’s very rare, the risk of reinfection exists.
Fluoride: the Right Daily Habit (Switzerland)
Le fluor renforce l’émail et aide à prévenir la carie. En Suisse, il est apporté par les dentifrices fluorés et le sel de table fluoré. Pour les adultes, visez un dentifrice entre 1000 et 1500 ppm; pour les enfants, adaptez la dose et la quantité (trace/pois) selon l’âge, en gardant la supervision parentale.

In Practice: how to Decide?
- If you are consistent and use good technique: a manual toothbrush may suffice.
- If you have gingivitis, braces, limited dexterity, or difficulty cleaning effectively: an electric toothbrush (ideally oscillating-rotating) will give you a measurable boost. In any case, daily interdental cleaning + fluoride make the real difference in the long run.
