multi-action power toothbrush

Brushing your teeth might seem simple, but how you do it matters. 

Numerous research shows that electric toothbrushes aren’t just easier to use—they clean more effectively, protect your gums, and support better long-term oral health.

1. Better Plaque Removal

A major Cochrane review (56 studies, 5,000+ participants) found that electric toothbrushes reduce plaque by 11% after 1–3 months, and by 21% after three months—compared to manual brushing.

*Why? *

Electric models deliver thousands of strokes per minute—up to 40,000 micro-movements—reaching areas manual brushing often misses, such as the back molars and along the gumline.

2. Healthier Gums

The same review reported a 6% reduction in gingivitis within the first few months, improving to 11% with continued use. 

Other studies confirm that electric toothbrushes reduce gum inflammation, bleeding, and recession more effectively than manual ones.

3. Stronger Long-Term Oral Health

An 11-year German study of 3,000 adults found that electric toothbrush users experienced 20% less tooth loss, 22% less gum recession, and 18% less tooth decay—clear evidence of lasting oral health benefits.

What to Look for in an Electric Toothbrush

✅ Timer and Pacer: Helps ensure two minutes of brushing with even coverage.

✅ Pressure Sensor: Prevents damage caused by brushing too hard.

✅ Long Battery Life: Ideal for travel; a charge lasting at least 2–3 weeks is recommended.

Points to Note:

If you have sensitive teeth or gums, consider sonic toothbrushes, which use ultra-soft bristles and high-frequency vibrations to clean thoroughly without irritation. 

For individuals with severe tooth wear or exposed dentin, sonic brushes are also gentler on enamel and soft tissue, helping to minimise the risk of further abrasion or gum recession.

刷牙看起来很简单，但“怎么刷”其实很重要。

多项研究表明，电动牙刷不仅使用更方便，还能刷得更干净，更有效地保护牙龈，并且有助于长期维持口腔健康。

1. 清除牙菌斑更有效

一项涵盖了56项研究、超过5000名参与者的Cochrane综述发现，使用电动牙刷1到3个月后牙菌斑减少了11%；使用3个月后减少了21%，效果明显超越手动牙刷。

这是因为电动牙刷每分钟可以产生高达40,000次微震动，能够深入清洁像后牙和牙龈边缘这些手动牙刷很难刷到的地方。

2. 更有效地保护牙龈

同一项研究还发现，使用电动牙刷几周内可减少6%的牙龈炎症状，持续使用能达到11%的改善。

其他研究也证实，电动牙刷在减少牙龈发炎、出血和萎缩方面，比手动牙刷更有效。

3.长期维持口腔健康

德国一项历时11年的研究，跟踪了3000名成年人，发现使用电动牙刷的人牙齿掉落率降低20%，牙龈萎缩减少22%，蛀牙也减少了18%，长期效果显著。

选择电动牙刷要注意什么？

✅ 计时与提醒功能：帮助你刷够医生推荐的两分钟，并提醒你平均清洁口腔四个区域。

✅ 压力感应器：防止你刷牙太用力，避免伤害牙龈和牙釉质。

✅ 电池寿命长：适合经常出差或旅行的人，建议选择一次充电可用至少2–3周的款式。

温馨提醒：

如果你有牙齿敏感或牙龈脆弱的问题，可以考虑使用声波电动牙刷。

它通过超柔软刷毛和高频震动，能温和又彻底地清洁牙齿，不会引起不适。

对于有牙齿磨损严重或牙本质暴露的人，声波牙刷也更温和，有助于降低牙釉质磨损和牙龈萎缩的风险。
