Bests & Worsts Reviews from Amazon

I am a dental professional with more than 20 years experience. I have recommended sonicare brushes for many years and will continue to do so because they are powerful and clean well, however, I cannot recommend this brush based on my personal experience. First, I purchased the brush at a professional discount so I only paid $60 for this item. Here is why I do not like this brush: 1. The brush head separates while using the toothbrush and I've seen this in other reviews. Anyone who paid $200.00 for a brush should expect a better quality. When I contacted sonicare they would not take back the brush because it was past 30 days, but could offer a 2 yr. warranty. I do not want a brush that does not work well so this would make no sense, They also advised I try a new brush head (additional expense) which I have done and it did not resolve the problem. 2. The brush head itself wears too quickly. It starts to flare within a month and once a brush flares it needs to be replaced. Brush head replacements are expensive. It also does not access all areas of my teeth as well as their older brush head models. 3. It does not clean my teeth as well as the older models. I have a problem with tartar build up on my lower front teeth and got my teeth cleaned every 3 months until I started using sonicare. I no longer had the buildup and even with 6 month cleanings there was no tartar build-up. With this sonicare I can see the build-up again and have to spend time scaling my teeth myself every few weeks. 4. I do not see the need for all of the different speed choices and truly question the efficacy of this. Neither have I seen any journal articles comparing the different brushes which included this model. I will continue to use sonicare, however, I will throw this one out and purchase one of the older, less expensive models which for me last longer and do a better job cleaning. However, to be completely fair I need to also tell you that two co-workers bought theirs at the same time I bought mine and they like their brushes and are having no problem with them. I think it depends on the individual mouth, not all are easily accessible although I believe mine is. They may not build tartar as I do. If you do decide to try this brush I would brush 3 or more x/day for the first 30 days just to see how it is working for you and if it is holding up. If everything goes well great, if not, immediately (within the 30 days) contact sonicare and return it for a refund. Also, amazon offers warranties by square trade which I believe are very good, but then after spending this much for a toothbrush, do you really want to spend more to warranty a toothbrush?
