Oral-B Triumph ProfessionalCare 9400
- Excellent cleaning
- Two-minute timer
- Signals when brushing is too hard
- Long battery life
- Expensive
- Frequency of sweeps could be better
Note: the Oral-B Triumph ProfessionalCare 9400 has been replaced by the Oral-B ProfessionalCare SmartSeries 4000.
Testing published in dental journals consistently says the pulsating and oscillating brush motion of the Braun Oral-B electric toothbrushes, which includes the Triumph ProfessionalCare 9400, excels at plaque removal. The 9000-series electric toothbrushes combine pulsation (in-and-out) and oscillation (side-to-side) movement. Experts say that whether you use a manual or electric brush, you need two minutes of brushing, and the Braun Oral-B Triumph ProfessionalCare 9400 has a two-minute timer and will also alert you if you're pressing too hard. The battery can go for longer than a month between charges.
The step-up model in the series, the Oral-B Triumph ProfessionalCare 9900 with SmartGuide includes a separate LCD panel that displays brushing information, but the toothbrush itself is the same as the cheaper 9400.
The Oral-B ProfessionalCare 9500 (known as the 9400 in the United States) and 9900 receive the best scores in a test of 12 electric toothbrushes by the British product-review publication Which? magazine. We found several clinical studies involving the Oral-B Triumph published in the Journal of Dentistry -- just be aware that the studies were commissioned by Procter & Gamble, maker of Oral-B. The findings, however, were not appreciably different from a German study published in the Journal of Orofacial Orthopedics or a review in Men's Health magazine. We found close to 70 user reviews on Amazon.com, almost all of them positive. ConsumerReports.org has skimpy coverage of electric toothbrushes, rating only four, and none in the Braun Oral-B ProfessionalCare 9000 series.

1. Which? magazine
This product-review magazine from the United Kingdom tests 12 electric toothbrushes. Testers use a laser scanner, sensor and video camera to determine how well the toothbrushes remove plaque from a model of four molars. The best results are achieved with the Oral-B Triumph 9900 with SmartGuide, but second place goes to the functionally similar Triumph ProfessionalCare 9500, which is the U.K. version of the 9400.

2. Journal of Clinical Dentistry
This clinical study with 98 subjects compares plaque removal with the Oral-B Triumph and the Sonicare Elite 7300 electric toothbrushes. After one brushing, the Oral-B Triumph removes more plaque than the Sonicare brush. Be aware, however, that this study is sponsored by the Procter & Gamble Company, makers of Oral-B toothbrushes.

About 250 owner reviews at Amazon.com give the Oral-B Triumph ProfessionalCare 9400 toothbrush a high average score. A few people think that the LCD display that shows feedback regarding brushing technique is unnecessary.

5. ExpoTV.com
ExpoTV lets product owners post amateur video reviews for items they've bought. The Oral-B Triumph ProfessionalCare 9400 is the subject of several positive reviews. While these are in no way professional, they contain real-life observations and give a good sense of the size of the toothbrush in a person's hand.
