I never thought I would use a sonic toothbrush due to the cost, but my dentist recommended it to me because of the plaque built-up and my gum were becoming unhealthy. I have already have the root cleaning done and I sure do not want that again, it hurt worse than having a baby! Therefore, when my dentist suggested it, I thought I would try one. There are so many brand and model, but at the dentist office they offer coupons and money rebates on the models they recommend. I have been using my Sonic Care toothbrush for over 1 year and it does make my mouth feel better when done brushing and I don't mind brushing because I know that it is helping my gums and teeth become more healthier. The only thing I do not like is that the replacement heads are expensive without a coupon. The heads cost for 2 around $25.00. I know you could buy a lot of regular toothbrushes for that price. But it works for me so I will pay the price to keep m own teeth for as long as I can.
