Best Electric Toothbrush So Far, January 10, 2008
I used an electric toothbrush before this, and so I assumed that the transition would be easy. Surprise! I at first found that the Triumph was shockingly rough! For the first week I had to use it on the gentle setting, but after a week I got used to it and switched to the normal setting. I found that that the monitor is useful to time the session and I think that it is worth the extra money.For what it is worth:
Normally when I visit the dentists office, the technician spends considerable time scraping off the plaque from my teeth. I went 2 weeks ago, and there wasn’t any plaque for her to remove. None. Additionally, I have rather poor flossing habits, and the technician usually causes my gums to bleed. This time she commented on how healthy my gums were – even between my teeth (I did not admit that I had not flossed in a month). Note: I am not advocating that you don’t floss, just admitting that I don’t.

What an awesome toothbrush! Not only do my teeth feel so much cleaner, my gums are looking much healthier and my teeth have brightened a bit — all in a month’s time!!My dentist suggested I purchase an Oral B toothbrush (he suggested a specific model, which was cheaper) because I have a bad tendency to overbrush and brush too hard causing my gums to be brushed away. This toothbrush is definitely saving my mouth. The 2 minute timer always seems to end before I’m done brushing — can you tell I really like this toothbrush? It’s just finally nice to have something that works as well as this does that also warns if and when you’re bearing down on your teeth too much along with the different brush heads and it intuitively knowing how to work with each of those.
I use the flossing brush head and the polishing head. Love them both.
