I have been using the Sonicare toothbrush for over fifteen years. The current model I am using is the Sonicare Essence e5500 electric toothbrush.
I use it three times a day, in the morning after breakfast, in the afternoon after lunch, and before bedtime. I have noticed much better breath when I use this product. I especially like the two minute timer. It encourages me to brush longer than I normally would without the timer.
Also, my gums use to bleed on a daily basis before I started using the Sonicare toothbrush. Now they never bleed. They also almost never bleed while at the dentist...
